Thor Oven Repair

Thor Kitchen has earned a strong reputation for offering heavy-duty, professional-style cooking gear that avoids the high price tags of legacy luxury brands. Whether you are using a dual-fuel model or a gas range in the damp climate of Seattle or the cold winters of Bend, these units are known for their high-BTU dual-ring burners and durable stainless steel build. Because these appliances are modeled after restaurant equipment, they utilize unique ignition systems, direct spark ignition (DSI) modules, and high-capacity gas safety valves that differ from standard kitchen appliances. In the popular Thor HRG and LRG series, we frequently address premature oven glow bar igniter failure or DSI spark modules that fail to ground properly, which causes a constant clicking noise without ignition. Thermocouple degradation is also common in all-gas models, leading to burners that shut off prematurely or fail to maintain a steady flame. Additionally, the heavy-duty door hinges on 36-inch and 48-inch units can experience spring fatigue, allowing heat to escape and throwing off temperature calibration. At A-Fix Service, our team is deeply familiar with Thor's pro-style engineering, from convection fan assemblies to mechanical thermostats, allowing us to restore your unit's performance with precision. We have serviced many of these units across the Pacific Northwest, tracking common failure points to ensure our vans are stocked with the correct parts for a lasting repair.

Repairing professional-grade Thor equipment requires specialized knowledge of high-voltage circuits and high-capacity gas systems. Proper repair demands manometer testing to verify manifold gas pressure, and adjusting the air shutter on a high-BTU burner requires exact calibration to avoid soot or carbon monoxide issues. Accessing internal parts often requires removing heavy stainless steel panels near high-heat zones. A common mistake we see is replacing a spark electrode without confirming the DSI module's grounding, which can instantly ruin a new part. Furthermore, dual-fuel Thor ranges require simultaneous troubleshooting of 240V electric elements and gas surface burners. Our techs carry the necessary multimeters, pressure gauges, and factory manuals to service these units safely. We offer a $90 diagnostic that is waived if you proceed with the repair. Because we stock common Thor OEM parts—such as silicon carbide igniters, dual-valve assemblies, safety gas valves, and convection fan motors—we typically finish repairs in one visit. Every repair is backed by a 1-year parts and labor warranty.

When you book a Thor repair with A-Fix Service, you receive a professional and transparent service experience. Our technician arrives in a fully stocked truck ready to address the symptoms you described. We begin with a systematic diagnostic of the gas and electrical circuits to find the failure point. For gas ranges that won't heat, we check the bake igniter continuity, verify voltage at the safety valve, and confirm thermostat calibration with a digital thermocouple. Once we identify the issue, we provide a clear, flat-rate estimate before starting work. There are no hidden fees or surprise charges. We maintain an inventory of high-turnover parts like selector switches, oven thermostats, and door hinges. If a rare part, such as a main control board, must be ordered, we use our supplier network to expedite shipping. Most standard repairs, like replacing a glow bar igniter or a convection fan motor, are completed in under two hours. We conclude every job by testing temperature cycling and checking for gas leaks to ensure your kitchen is safe.
