Often asked: What Is A Thermopile On A Water Heater?

How do I know if my thermopile is bad?

Diagnosing a Thermopile Problem Just like the thermocouple, the thermopile can be read with a multimeter to check if it’s the cause of the problem. Three hundred millivolts or higher voltage is a sign of a good thermopile. A reading below 300 millivolts would require you to replace the thermopile.

How do you fix a thermopile?

Replacing a Thermopile

  1. Turn off the Gas Supply.
  2. Disconnect the Wires.
  3. Remove the Manifold Door.
  4. Remove the Pilot Assembly and Thermopile Wire.
  5. Place the New Thermopile Wire.
  6. Feed the Wires Through the Manifold Door.
  7. Install the Manifold Component Block.
  8. Reconnect the Thermal Switch Wiring.

What does thermopile low voltage mean?

If the thermopile does not generate the correct voltage, the heater may fail to provide you hot water. So, this is what the thermopile voltage low error means. The error means the thermocouples in the collection cannot generate enough current to power the control panel that we mentioned.

Will a pilot light stay lit with a bad thermocouple?

A thermocouple senses the heat of the pilot and allows gas to flow to the burner. A bad thermocouple will shut off gas to both the pilot and the burner so the pilot light won’t stay lit.

How much is a thermopile?

It costs $150 to $250 to replace a thermocouple. It checks to make sure the pilot light is on. It will shut the gas off if it’s not.

How long does a thermopile last?

All things considered, the question remains, “How long should my thermocouple last?” The answer to that question is that it depends on the application. In an ideal environment, that length of time can be indefinite.

How many millivolts does a good thermopile produce?

The normal millivolt output is 25 to 35 millivolts; on some, you may even get up to 35. The other part of this safety pilot system is the electromagnet (power unit).

How do you clean a thermopile on a water heater?

Clean the thermocouple – using the emery cloth sandpaper, sand the ends of the thermocouple and then give it a finishing touch with the lint-free cloth. Hopefully, you can get to the ends of the thermocouple without having to detach it from the assembly, but you may have to do that.

What’s the difference between a thermopile and a thermocouple?

The main difference between Thermocouple and Thermopile is their method of measurement. The thermocouple is a thermoelectric instrument, while the thermopile is an instrument that modifies thermal energy into electrical output.

How much does it cost to replace a thermocouple on a water heater?

Thermocouple – $20 to $150 The thermocouple is an apparatus that senses whether the pilot light is lit and triggers the gas control valve. Repairs typically cost about $150 to have it done professionally, though a new thermocouple itself only costs about $20 on average.

How does a thermopile create voltage?

A voltage is generated in a thermopile when its dissimilar metals (thermocouples) are exposed to temperature differences. Adding more pairs of thermocouples in series to form a thermopile, it increases the voltage output.

How many volts does a thermopile produce?

A thermopile is used for a standing pilot system and generally produces around 600-750 millivolts. This voltage is used by the gas valve to keep the pilot valve solenoid internal to the main gas open and also provides the voltage needed to run the gas valve and safeties.
