Why does my ventless heater keep shutting off?

If the thermocouple is too far from the flame, this can cause the pilot to go out and shut down the propane heater; you can fix this easily by moving the thermocouple closer to the flame. The thermocouple could also be worn out, in which case it needs to be replaced.

What happens when a thermocouple goes out?

If the appliance has a thermocouple, the problem may be a faulty thermocouple. The thermocouple, which operates as a safety device, turns the gas supply off when the pilot light goes out. When a thermocouple fails, the pilot light won’t stay lighted. A burned out or broken thermocouple should be replaced.

Can a faulty thermocouple cause a water heater to go out?

The pilot can go out for a number of other reasons, however, so if you’re having trouble getting the pilot to stay lit, the thermocouple may not be at fault. Here are a few ways to pinpoint a faulty thermocouple as the culprit. The Pilot Lights But Won’t Stay Lit If a water heater pilot won’t light at all,…

Why are the lights going out on my thermocouple?

The reason for the lights going out could be due to clogged air intake vents. If the vents are clogged, turbulence is caused when the main burner shuts down putting out the pilot. Check for clogs at the pilot orifice by passing a thin wire through it even if you can see daylight at the other end.

Can a bad thermocouple cause a gas furnace to stop working?

A bad thermocouple itself can prevent a gas furnace or boiler from working – if you can light the flame at the pilot manually but then the flame goes out when you release the manual gas feed valve, the thermocouple is probably bad. What’s the Difference Between a Thermopile and a Thermocouple?

Can a thermocouple go out when the pilot is on?

Nothing lasts forever, and when the thermocouple wears out, the pilot won’t stay lit and your appliance won’t work. The pilot can go out for a number of other reasons, however, so if you’re having trouble getting the pilot to stay lit, the thermocouple may not be at fault.

What does the thermocouple do in a propane heater?

The thermocouple is the heat-sensitive safety device that prevents the release of unburned gas. The initial flame of the pilot heats the thermocouple, which will signal the valve to stay open and keep the pilot lit and the propane heater functioning.

Why is the pilot light on my gas water heater not working?

If the thermocouple is bent too far away from the pilot, the entire water heater will not function properly. If you follow proper safety precautions and turn your gas off, you may be able to bend the thermocouple back into place. The thermocouple is too dirty.

Why does my propane heater not stay lit?

When a propane heater won’t stay lit, often what is happening is that the propane heater may sense that the flame is defective in some way, triggering the propane heater’s safety functions and causing it to shut off. The problem may be a genuine defect or it could be an issue with the sensor.

Why is my thermocouple not reading my temprel?

If finding that the thermocouple does not read, the problem is most likely a bad connection, broken wiring, or open internally within the thermocouple probe circuit. Inaccurate Readings?
