Resideo Q340A1090 Thermocouple
The Resideo Q340A1090 is a heavy-duty universal 30mV thermocouple designed for gas-fired heating applications including furnaces, boilers, and water heaters. This pilot safety thermocouple features a 36-inch lead length and a standard 11/32-32 male connector nut, ensuring compatibility with most standing pilot gas valves. With an open circuit output range of 26mV to 32mV and a low internal resistance of 0.02 Ohms, it provides reliable flame rectification and millivolt signal stability. This unit serves as the direct cross for 600003 and is a versatile truck stock item. The kit includes a push-in clip and an adapter for broad installation flexibility across various burner headers. When troubleshooting a pilot that won't stay lit despite a clean orifice, replacing the existing sensor with this high-performance lead ensures accurate millivolt drop readings and consistent solenoid engagement. Use this furnace thermocouple replacement to restore system reliability for Residential gas heating systems.
- Universal Compatibility: Includes mounting hardware and adapters to fit most standard pilot burner assemblies.
- Optimized Signal: Delivers a consistent 30mV nominal output to maintain a strong hold-in current for the gas valve.
- Direct Cross-Reference: Engineered as a drop-in replacement for the 600003 model, simplifying field selection.
- Durable Construction: High-temperature lead designed to withstand thermal cycling without premature fatigue.
How do I know if the Q340A1090 is compatible with my existing gas valve?
This model utilizes a standard 11/32-32 male connector nut. If your gas valve uses a threaded connection of this size and requires a 30mV signal, this universal lead is the correct choice.
What is the purpose of the included adapter and push-in clip?
The adapter allows for use in snap-fit or clinch-type pilot burners, while the clip secures the thermocouple tip at the correct height within the pilot flame for optimal heat transfer.
Can I use this 36" lead to replace a shorter 24" thermocouple?
Yes, the 36" length provides extra flexibility. Any excess lead should be carefully coiled away from the burner flame to avoid heat damage to the insulation.
