Thor Gas Appliance Repair

Thor Kitchen has earned its place in PNW homes by offering pro-style gas equipment that favors mechanical reliability over complex digital boards. Their HRG and LRG series ranges are favorites across Washington and Oregon for their high-BTU dual-ring burners, heavy-duty continuous cast iron grates, and simple analog control valves. Since these units lack digital diagnostics, our technicians focus on raw gas mechanics—including gas pressure regulators, thermocouple operation, and manual spark modules. Frequent issues include DSI (Direct Spark Ignition) modules clicking due to moisture from coastal humidity, oven safety valves failing to open because the hot surface igniter isn't drawing enough current, or brass burner orifices getting clogged by debris, leading to yellow, sooty flames. At A-Fix Service, we are experts in Thor's engineering, including their sealed burners and infrared gas broilers. Whether you have a 30-inch unit in a Seattle apartment or a 48-inch double-oven range in a Bend home, we provide precise, component-level repairs without needing a computer readout.

Repairing Thor gas equipment is not a task for homeowners due to the dangers of handling gas and the precise calibration required for high-output burners. Replacing a gas valve or adjusting a regulator requires a manometer to verify water column (WC) pressure—specifically 5 inches WC for natural gas and 10 inches WC for liquid propane. Incorrect pressure can lead to dangerous flare-ups or carbon monoxide buildup. Furthermore, accessing the internal gas manifold requires careful removal of the front bullnose and control knobs without scratching the stainless steel. Our technicians carry digital manometers and combustible gas leak detectors to ensure your appliance is safe. Bypassing safety features or using non-OEM parts is dangerous and can void your insurance. We charge a $90 diagnostic fee, which is waived if you proceed with our repair, and every job includes a 1-year warranty on parts and labor.
