What causes a thermocouple to go bad on a hot water heater?
It’s Dirty. Soot buildup on the thermocouple may block the flame. Under constant exposure to a hot flame, a thermocouple wears down over time. Even a slight residue can make the thermocouple malfunction.
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 does my whirlpool water heater not heat water?
Hunker may earn compensation through affiliate links in this story. A bad thermocouple is the most likely culprit when your Whirlpool water heater fails to heat the water in the tank. The pilot light heats the thermocouple, which generates electric current that tells the gas control valve/thermostat to continue to feed gas to the burner assembly.
Where is the thermocouple on a whirlpool water heater?
Use an adjustable wrench to loosen the thermocouple from beneath the gas control valve/thermostat by turning it counterclockwise. The thermocouple is a thin copper tube attached to the left of the manifold tube. Use the adjustable wrench to loosen the pilot tube by turning it counterclockwise.
What happens when the pilot light goes out on a whirlpool water heater?
The pilot light heats the thermocouple, which generates electric current that tells the gas control valve/thermostat to continue to feed gas to the burner assembly. If the pilot light should go out, the thermocouple closes the gas control valve/thermostat by interrupting the electrical current.
