🔧 Key Features & Benefits
-
✅ Genuine OEM Replacement – Ensures full compatibility and safe operation.
-
✅ Universal 750mV Output – Works with most millivolt control valves and gas regulators.
-
✅ Reliable Performance – Provides stable voltage generation for consistent flame control.
-
✅ Heavy-Duty Construction – Copper and nickel-plated terminals withstand heat and corrosion.
-
✅ Plug-and-Play Installation – Easily fits existing pilot assemblies — no modifications required.
🔥 How It Works
The thermopile sits in the pilot flame and generates a small electrical current (millivolts) from heat. This current powers the gas control valve and thermostat circuit, allowing safe and automatic temperature regulation without external power.
A weak or faulty thermopile can cause your heater to not stay lit, fail to start, or shut off unexpectedly — replacing it restores full functionality.
