Thor Oven/Stove Repair (Model HRG3618U) – Salem, OH

A homeowner in Salem called about their Thor gas range — the front left burner wouldn’t light despite normal sparking. We found a clogged burner orifice blocking gas flow, a common issue on dual-ring burners that see heavy use.

The Problem

The customer reported that the front left burner on their Thor HRG3618U would spark normally but wouldn’t ignite. They had tried basic cleaning around the burner cap and grate, but the issue persisted. The other burners were working fine.

Diagnosis

We removed the burner cap and inspected the dual-ring assembly. The igniter was functioning properly with good spark, but we discovered the small inner orifice was completely blocked with cooking residue and debris. This prevented adequate gas flow to sustain ignition, even though the spark system was working correctly.

The Repair

• Parts replaced: None — cleaning repair
• Work performed: Cleaned out the small left double burner orifice using specialized tools
• Result: Burner now ignites immediately with proper flame pattern on both rings

Is It Worth Repairing?

Thor ranges are professional-grade appliances built to last decades with proper maintenance. A simple orifice cleaning like this extends the life significantly and costs far less than replacement. These units are designed for heavy commercial use, so home cooking rarely wears them out prematurely.

Maintenance Tips for Thor Gas Ranges

• Clean dual-ring burner orifices monthly using a thin wire or needle to prevent blockages
• Remove and wash burner caps weekly — Thor’s brass fittings can corrode if grease builds up
• Check that the continuous grates sit level — warped grates can affect flame distribution on Thor’s high-BTU burners
