Testing for Gas Leaks Do not ever use a flame to test for gas leaks, as doing so may result in explosion, injury, death, and/or damage to the appliance and property _ARA_EN_D Page 7 of 92

7 With electrical power off, carefully check for gas leaks at each gas component that was removed, replaced, or otherwise serviced using a gas leak detector (electronic leak detectors are highly recommended) or bubble test. The only exceptions that may require the electrical power on are for XLO valves and bi-metal gas valves. For these components, use extreme caution when performing gas leak testing with electrical power on. Sharp Components This appliance has sheet metal and other components which often have sharp edges. When working on this appliance, avoid cutting yourself and other injury by handling these parts with care and using adequate protective measures, such as gloves. Electrical Hazards Before servicing the appliance, remove electrical power by disconnecting the power cord from the wall receptacle, by shutting off the circuit breaker, or by disconnecting the proper fuse. If tests have to be conducted while the appliance is live, always use a residual-current-operated circuit-breaker. The protective conductor connection must not exceed the recommended values. When repairs are complete, perform a function test in accordance with the appropriate regulations. Do not under any circumstances cut or remove the separate ground wire or the third (ground) prong from the power cord plug. Improper grounding or reverse polarization will cause malfunction (such as continuous sparking of the igniters), which can damage the appliance and create an electrical shock hazard. Make sure the circuit is properly grounded and polarized in accordance with applicable local codes and ordinances. Receptacle replacement shall be in accordance with the National Electric Code. Hot Surfaces To avoid burns and injury, do not handle components and surfaces that are hot, such as the rangetop burner assemblies, maintop, griddle/grill, gas burners, electric elements, hot surface igniters, heat deflector, and interior oven surfaces, or the exterior area immediately surrounding the door. In Case of Power Outage When there is a removal of electrical power, the XLO / XHI burners and griddle/grill cannot be used. Do not attempt to light them manually during a power outage. If for any reason a control knob is on when there is any failure or removal of electrical power from the appliance (such as a power outage), immediately turn all control knob(s) to the OFF position. Ventilate well by opening a door or window, and wait at least 5 minutes for all the gas to dissipate. If you smell gas, refer to the applicable safety precautions stated in this manual. Clean-up Hazards Don t allow any cleaning or polishing solutions/compounds, disinfectants or bleaches to remain in contact with the stainless steel surfaces for long periods, or after clean-up. These may contain chemicals or materials which could release harmful inhalants and can damage the appliance. After cleaning or polishing, always rinse the cleaning/polishing materials with clear water and wipe dry with a clean soft, non-abrasive cloth. Never use bleach-containing or chlorinated cleaners, as they act as oxidizers on metal surfaces _ARA_EN_D Page 8 of 92

8 Clean the range with caution. Do not use flammable cleaners to clean the range. Avoid steam burns; do not use a wet sponge or cloth to clean the range while it is hot. Do not use any type of aerosol cleaner on or around the rangetop when hot. Some cleaners produce noxious fumes if applied to a hot surface. Follow directions provided by the cleaner manufacturer. Fiberglass Insulation Wear gloves when handling fiberglass insulation. Prior to Returning Appliance to Service Prior to returning the appliance to service, make sure that: All electrical connections are correct and secure All safety grounds (internal and external) are correctly and securely connected All gas connections are secure and have been leak tested using a gas leak detector or bubble test. All panels and components are properly and securely reassembled Oven Door, Oven Accessories and Oven Gasket Use caution when opening the oven door during or immediately after operation. Stand to the side of the oven when opening an oven door to allow hot air to escape. Keep face well away from the open door to avoid injury. Before self-cleaning an oven, remove the broiler pan, oven racks, any utensils, as well as excessive spillage Do not clean, rub, damage, move, or remove the door gasket, as it is essential for providing a tight seal during oven operation. If the gasket becomes worn or excessively soiled with food particles, replace the gasket. Backguard Ventilation To ensure sufficient airflow for proper oven performance, do not block or obstruct the vents located on the backguard (high backguard, lowback, or island trim). Backguard vents and surrounding areas are hot. Do not place plastic, other heat-sensitive items, or flammable / combustible materials on or near the backguard vents, as these areas could melt or ignite. Don t touch or clean the backguard vent area while the appliance is on, nor for several minutes after the appliance is turned off, to prevent burning yourself _ARA_EN_D Page 9 of 92

11 3 TESTING, ADJUSTING, AND TROUBLESHOOTING RANGETOP BURNERS AND IGNITION Servicing Burners and Ignition Burner and ignition servicing must be performed by a qualified technician. Improper adjustments may be dangerous, cause damage or harmful by-products, and may void the appliance warranty. 3.2 Rangetop Burner Characteristics If one or more rangetop burner blows out, the respective igniter electrode automatically re-ignites the flame. The flame should burn through each burner port, completely around the burner cap (see Figure 4). Ignition Hazard Do not touch burners when the igniters are active (sparking). 3.1 Before Testing Before testing rangetop burners and ignition, do the following: 1. Reinstall any loose components that may have been removed earlier, such as burner caps, griddle/grill, and grates. Be certain that burner caps seat properly into the burner bases, burner bases and Venturi tubes are aligned correctly, and that the ignition wires are properly positioned. 2. To test for gas leaks, make sure the electrical power is removed and the manual gas shut-off valve is open, and then carefully check range components and gas supply for leaks using a gas leak detector or bubble test. 3. After gas checks are complete and before testing, connect the range to the electrical power supply. Figure 4: Burner Ports 1 Burner ports It is normal to hear the following during burner operation: A slight sound that is associated with gas combustion and ignition. There should not be a loud noise. A clicking noise every time the gas cycles, coming from the solenoid valves of the two left burners If using LP gas, a slight pop sound may be heard at the burner ports a few seconds after the burner has been turned off _ARA_EN_D Page 12 of 92

12 3.3 Rangetop Flame Characteristics Natural gas: The rangetop burner flame color should be blue with no yellow on the tips (see Figure 5). It is not uncommon to see orange in the flame color; this indicates the burning of airborne impurities in the gas, and will disappear with use. See Figure 6 for additional flame characteristics. LP gas: Slight yellow tips on the primary flame cone are normal and may appear after a few minutes. The flame should be stable with no excessive noise or fluttering. Orange colored streaks in the flame are produced from burning airborne debris, which is normal at startup, and should dissipate in a few minutes (see Figure 6). When the flame is properly adjusted, it should burn completely around the burner cap, at each burner port (see Figure 4, page 12). Figure 6: Additional Flame Characteristics NOTE: If rangetop burner/flame characteristics are not adequate, see Troubleshooting Burners, Flame, and Ignition, page 16). Figure 5: Correct Flame Color and Characteristics 1 Dark blue 2 Secondary cone 3 Light blue 4 Primary cone _ARA_EN_D Page 13 of 92

13 3.4 Testing Ignition for Burners Ignition Hazard Do not touch the rangetop burners when the igniters are sparking Time to Ignite For each burner, push the control knob in and then turn counterclockwise to the highest setting. The igniter should produce a clicking sound as the burner is sparking, and the burner should light within 4 seconds. NOTE: It is normal for a burner to spark when a knob is pressed in, or turned slightly Testing Ignition for Standard Burner Settings (HI, MEDIUM, SIM) Testing Broil Burner Ignition Set the mode to BROIL. After less than a minute (depending on the model) the burner should ignite. The broil burners do not have an air shutter, and no adjustment is necessary Testing Bake Burner Ignition Set the oven to BAKE at 350 F. After less than a minute (depending on the model) the burner should ignite and stay lit until 350 F is reached. During preheat and also during bake mode, the burner cycles on and off to maintain the temperature. 3.5 Adjusting Bake Burner Flame with the Air Shutter The bake burner has an air shutter system (see Figure 7) that is factory pre-set to burn optimally, but depending on the quality of the gas available, may require adjustment. Set the burner knob to HI, and observe flame characteristics (see Figure 5 and Figure 6). If any burner flame burns primarily yellow, verify if the burner cap is positioned properly on the burner base, and then re-test. Repeat test for MEDIUM and SIM settings. If flame characteristics do not improve, call Thermador technical support at (800) Testing Ignition for XLO Burner Settings Set the burner knob to XLO and observe if the flame cycles correctly. It should be on for approximately 8 seconds, and then off for approximately 52 seconds of each minute. Figure 7: Typical Air Shutter 1 Air shutter 2 Adjustment screw(s) 3 Opening _ARA_EN_D Page 14 of 92

14 1. First remove the bake burner from the burner box. For the large oven, see Bake Burner Components (Large Oven) Removal and Replacement, page 78. For the small oven, see Bake Burner Components (Small Oven) Removal and Replacement, page Loosen the adjustment screw, and then rotate the air shutter to modify the opening as follows: If the flame is lifting or blowing, or is not carrying over, rotate the shutter clockwise to set the opening to a more closed position. If the flame is too yellow, rotate the shutter counter-clockwise to set the opening to a more open position. 3. Tighten the adjustment screw. 4. Reinstall the burner. 5. Test to evaluate the flame characteristics. 6. Repeat this procedure as needed until the flame characteristics are optimal. 3.6 Adjusting Rangetop Burner Valves Manually Although pre-adjusted, if you need to set the valves for the lowest possible flame setting, then manually adjust the bypass screws on the valves. Figure 8: Bypass Screw on Valve (View with Control Panel Removed) 1 Bypass screw on all valves Special Tools Needed To reposition the bypass screws for minimum flow settings on manual valves, use a precision high-strength blade screwdriver, with a 1/8 inch (3.0 mm) wide,.020-inch (0.50 mm) thickness tip _ARA_EN_D Page 15 of 92

15 3.6.2 Adjusting the Bypass Screws m Caution Potentiometer Failure Failure to turn off electrical power when adjusting bypass screws may cause failure of the potentiometers 1. Turn off electrical power by unplugging the power cord, or putting the circuit breaker in the OFF position. 2. Remove knobs from valve stems by slowly pulling knobs straight out, away from control panel. 3. Remove and retain the right bezel mounting screw. 4. To engage the valve screw, insert the precision screwdriver with a 1/8 inch blade into the same hole in the bezel that was created by the removal of the right side mounting screw. 5. Turn the valve screw clockwise just until "bottom out" position is reached. Don t over-tighten the valve screw. NOTE: The XLO valves must be in the XLO position for proper access to the valve screws through clearance hole in the potentiometer. NOTE: The griddle/grill is electric, controlled by a thermostat and does not have a valve that requires adjustment. 3.7 Troubleshooting Burners, Flame, and Ignition Burner and Flame Diagnostics for Rangetop Burners If a rangetop burner clicks (sparks) constantly or if burner doesn t light correctly and/or has inadequate burner/flame characteristics (per Rangetop Burner Characteristics, page 12 and Rangetop Flame Characteristics, page 13), then do the following: Check if manual shut-off valve is open and unit is receiving gas. Check if the burner cap is properly aligned on the burner base. Check if the burner port is open and not clogged or blocked. Check if the igniter electrode is free from debris and is sparking. If it is suspect that air is in the gas supply lines and system, you can purge the remaining air by operating one of the burners for several minutes. Check if a fuse has blown or a circuit breaker has tripped. Check polarity For constant sparking, check wiring connections at ignition (spark) module and electrode, and also check grounding. For intermittent sparking, check the pot spacing, flame height, and drafts in kitchen. Refer to the Ignition Diagnostics for Rangetop Burners, page 16. Call Thermador technical support at (800) for assistance if any burners fail to light, or any burners continue to burn yellow Ignition Diagnostics for Rangetop Burners Gas Leaks With electrical power off, carefully check for gas leaks at each gas component that was removed, replaced, or otherwise serviced using a gas leak detector (electronic leak detectors are highly recommended) or bubble test. For non- standard (XLO) valves, the electrical power may need to be on when testing. Use extreme caution when performing gas leak testing on XLO valves. The following flowchart applies in the event a burner fails to ignite. Before performing steps in the Diagnostic Flowchart for Rangetop Burner Ignition (Figure 9, page 17), remove electrical power from appliance during disassembly and during removal and installation procedures. Restore electrical power when testing the unit if it is reassembled _ARA_EN_D Page 16 of 92

17 4 DIAGNOSING HOT SURFACE IGNITERS, GRIDDLE / GRILL ELEMENT, OVEN LIGHTS, TEMP SENSORS 4.1 HSI and Element Diagnostics Cycle/Circuit Specification Cavity Mode HSI/Element Watts Volts Amps Ohms small, Bake Bake burner HSI large small, Broil Broil burner HSI large small, large Convection Bake Bake burner HSI Griddle / Grill Griddle / grill N/A NOTE: For element specific models Safety Practices for HSI and Element Diagnostics Observe all pertinent safety practices such as warnings, cautions and instructions contained in the Safety Precautions to Know Prior to Servicing section of this manual (page 7), throughout this manual, and the Installation Manual. Ensure compliance with all applicable codes HSI and Element Diagnostic Tips General The electrical wiring diagram is located behind the kick panel of the range (see Wiring Diagram, page 6). Bake and broil modes cannot be operated simultaneously in any single oven cavity. Resistance Reading You can perform a resistance reading on an HSI or the griddle/grill element with the electrical power to the range turned off. Amperage Reading: Broil mode: Broil burner remains on until reaching the maximum temperature, and cycles off and on to maintain that temperature. Bake mode: The power to the bake burner cycles on and off at pre-set intervals when the bake burner is preheating (preheating indicator light is on) and also during regular bake cycle (after preheating). Electric griddle/grill element and HSIs: Check either HSI/element wire with an amp meter and amp clamp. NOTE: Always check an HSI at one of its wire connectors, as the gas burner (attached to the other end of HSI) will ignite. NOTE: Although the HSI may be glowing, if not enough current is running through it, the safety valve may not open. Alternatively, you can check the electric griddle/grill element or HSIs at the wires going to the hot or neutral terminals of the terminal block. Alternatively, you can check the electric griddle/grill element or HSIs from the corresponding I/O relay terminals on the main control board. Temperature Reading Do not remove the thermocouple prematurely when the oven is hot. Use a thermometer with a thermocouple leads to test the oven temperature. If you leave the thermocouple in the oven during a speed clean cycle, keep in mind it will take a few hours before the oven is cool enough if you plan to retrieve the thermocouple. Convection Bake For convection bake, you can visually inspect if the convection fan is working. The convection fan only works after the preheating finishes, thus it may take less time to test the convection fan on the lowest bake convection setting. 4.2 Oven Light Diagnostics To diagnose problems with the oven light (for all ovens), see Oven Light Diagnostics (Figure 10, page 19).
