2. Introduction Is your APW Wyott griddle struggling to maintain the right cooking temperature? The APW Wyott AS-2000100 thermostat plays a key role in controlling heat on compatible commercial griddles. It senses the temperature of the griddle plate and regulates the heating system to help maintain the selected temperature. Accurate temperature control supports consistent cooking results in restaurants, cafeterias, hotels, and other foodservice kitchens. A faulty thermostat can lead to common APW Wyott griddle temperature problems, including overheating, slow heating, failure to reach the set temperature, or frequent temperature fluctuations. These issues can affect food quality, increase energy consumption, and cause operational downtime. This blog explains how the APW Wyott griddle thermostat works, the common AS-2000100 thermostat problems to watch for, and key signs that may indicate the component needs inspection or replacement.
3. What Does the AS-2000100 Thermostat Do? How It Works The Sensing Cycle The thermostat senses griddle plate temperature via a capillary tube When the temperature drops below the set point, heating continues. and sensing bulb. It signals the heating system to cycle on or off, Once the target is reached, the thermostat interrupts the heating cycle— maintaining a constant cooking temperature for consistent results. preventing overheating while keeping the surface at the desired temperature. If the thermostat or sensing system fails, the griddle may overheat, underheat, or fluctuate significantly during operation.
4. What Are the Common APW Wyott AS-2000100 Thermostat Problems? An APW Wyott AS-2000100 thermostat can develop problems that affect how accurately a commercial griddle controls temperature. The most common issues are the APW Wyott griddle not heating, overheating, and inconsistent temperature cycling. 🔥 Overheating 🌡️ Uneven Heat Thermostat fails to shut burners off at the set temperature. May also Loose or improperly positioned sensing bulb causes inaccurate involve a faulty high-limit safety switch. readings and hot spots across the griddle surface. ⚡ Erratic Cycling ❄️ No Heat Rapid on/off switching causes temperature swings and difficulty An APW Wyott griddle not heating may indicate a failed thermostat or maintaining the selected setting. another component in the heating circuit. Other possible causes include a faulty igniter, blown fuse, damaged wiring, failed burner component, or defective heating element, depending on the specific griddle configuration. Always diagnose systematically — the thermostat is not always the root cause of temperature problems.
5. Safety First: Before You Begin Turn off the equipment and disconnect the appropriate power or gas supply before inspecting any components. Gas-fired and electrically heated commercial griddles must be serviced according to the manufacturer's instructions and applicable safety requirements. Power Off Turn off and unplug the griddle, or shut off the gas supply. Cool Down Allow the griddle to cool completely before touching any components. Access Panel Remove control knobs and front panel to reach the thermostat, high-limit switch, and wiring.
6. How to Diagnose the Thermostat: Step-by-Step Inspect Wiring Test Continuity Check Response Inspect Components Use a multimeter on the lowest Ω setting to test continuity. With the thermostat calling for heat, near-zero resistance indicates continuity; an OL or infinite reading suggests a defective thermostat.
7. Power Off and Access the Thermostat Turn off and unplug the griddle, or shut off the gas supply. Allow it to cool completely, then remove the control knobs and front panel to access the thermostat, high-limit switch, and wiring. Inspect the Thermostat and Sensing Bulb Check for visible damage, loose terminals, burned wiring, or corrosion. Ensure the sensing bulb is firmly secured beneath the griddle plate. A loose bulb can produce inaccurate temperature readings. Test Continuity Disconnect the thermostat wires and use a multimeter on the lowest Ω setting. With the thermostat calling for heat, near-zero resistance generally indicates continuity. An OL or infinite reading indicates an open circuit and may indicate a defective thermostat.
8. Check Temperature Response If properly equipped and trained, verify whether the thermostat changes state as temperature increases. An erratic or absent response can indicate thermostat failure or calibration problems. Check Other Components If the thermostat tests correctly, inspect related components such as the burner element, igniter, thermal fuse, wiring, or gas controls. A temperature problem does not always originate with the thermostat. Safety Note: Gas-fired and electrically heated commercial equipment can present fire, burn, and electrical hazards. Follow the manufacturer’s service instructions and have qualified technicians perform live electrical or gas-system testing.
9. How to Replace the AS-2000100 Thermostat If diagnostics show the AS-2000100 thermostat is faulty, replacement is usually straightforward. Follow these general steps (specific models may vary slightly): 01 02 03 Get the Correct Part Shut Down & Cool Remove Old Thermostat Verify the AS-2000100 part number and Disconnect electrical power and shut off gas. Photograph or label wiring before compatibility with your APW Wyott griddle Allow the griddle to cool completely, then disconnecting. Remove from mounting bracket before purchasing. remove the knobs and front panel. and carefully release the sensing bulb. 04 05 Install & Reconnect Reassemble & Inspect Mount the replacement in the original position. Secure the sensing bulb Reinstall all panels and knobs. Confirm wiring is secure and clear of hot beneath the plate and reconnect each wire to its proper terminal. surfaces before restoring utilities.

10. How to Test an APW Wyott Griddle After Thermostat Repair Once you’ve replaced the thermostat, it’s critical to verify the repair before returning the griddle to service. Follow these testing steps: Ignition & Startup Temperature Accuracy Restore power and gas. Verify normal ignition. Stop immediately if Compare plate temperature (measured with a calibrated you notice a gas odor, unusual noise, or abnormal operation. thermometer) against the thermostat setting. Readings should align closely. Burner Cycling Heat Distribution The burner should turn on while heating and shut off when the set Measure several areas of the griddle surface.

13. Frequently Asked Questions Why does my griddle keep overheating? A faulty thermostat, high-limit switch, or loose sensing bulb can cause overheating. Secure the bulb first, then test the thermostat and hi-limit switch and replace the failed component. Why won't it reach the set temperature? A faulty thermostat, burner, igniter, or loose sensing bulb may prevent proper heating. Check the bulb and thermostat first, then inspect the burner and ignition system. How often should the thermostat be replaced? There is no fixed replacement schedule. Replace the thermostat when it fails testing, gives inaccurate temperatures, or cannot maintain the selected setting.
