What is a thermopile

Thermopiles are used for contactless temperature sensing. The function of a thermopile is to transfer the heat radiation emitted from the object to a voltage output. The output is in the range of tens or hundreds of millivolts. Thermopiles work as sensors or generators.

Is a thermopile and a thermocouple the same thing?

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.

What does a gas fireplace thermopile do?

Thermopile is a an important device that converts thermal energy into electric energy. The purpose of a thermopile in a gas fireplace is to detect thermal radiation, for gas burner safety control.

What is the difference between a thermocouple and a thermocouple?

The thermocouple and thermopile are distinguished by the fact that the thermocouple is a thermoelectric device and the thermopile is a device that converts electrical energy into thermal energy.

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 long does a thermopile last?

Thermopile sensors don't have a specific life expectancy or degradation rate. As long as they are used correctly and maintained properly, thermopiles can last for years or even decades and remain in good working condition.

Do all gas fireplaces have a thermopile?

Any gas appliance with a standing pilot needs a thermocouple to keep the pilot lit, whether it cycles on and off automatically, like a water heater, or you operate it manually, like a gas fireplace.

How do you replace a thermopile?

And the way you remove it is you pinch it or just pull it from one side and it'll come off the next

How do you test a thermopile?

Make sure the unit on/off switch wall switch while thermostat or remote is in the off position to

Why does the pilot light keep going out on my gas fireplace?

A faulty, misaligned, dirty, or damaged thermocouple is often the culprit behind your pilot light going out. The thermocouple is an automatic safety shutoff device that prevents the gas valve from opening if the pilot light is out.

What would cause a gas fireplace not to ignite?

One of the most common reasons a gas fireplace won't turn on is often an extinguished pilot light. A strong downdraft, an interruption in the fuel line, or a build-up of soot and dust can cause the pilot light to flame out.

Why does a thermopile fail?

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.

What are the 3 types of thermocouples?

Primarily there are eight types of thermocouples: B, E, J, N, K, R, T, and S type.

B-Type Thermocouple. The alloy combination is of Platinum (6% Rhodium) and Platinum (30% Rhodium).
E-Type Thermocouple. ...
J-Type Thermocouple. ...
K-Type Thermocouple. ...
N-Type Thermocouple. ...
R-Type Thermocouple. ...
S-Type Thermocouple. ...
T-Type Thermocouple.

Can I bypass a thermocouple?

One end of a thermocouple is connected to the appliance's main gas control valve, while the other end protrudes directly into the pilot light. To disable thermocouples, either one end or the other needs to be removed from the source.

Should thermocouple be in pilot flame?

The pilot flame should touch the thermocouple at a specific level. If the flame is blue and weak, and barely reaches the thermocouple, it needs to be stronger. If it extends well above the thermocouple, it's too strong.

How much does it cost to replace a thermopile?

The part is rather small and inexpensive, but replacing it requires the expertise of a professional plumber for safety reasons. Having a thermocouple replaced usually costs $125-200, while the part itself is about $15-25.

Can a thermopile be cleaned?

Yes, you can clean a thermocouple, but the task must be done with a light touch. Remove the thermocouple from the process assembly, using a steel wool or emery cloth, lightly clean the tip removing any build up.

What are the symptoms of a bad thermocouple?

Failed Thermocouple Symptoms The first is signs of contamination on the tube, which can include discoloration, cracks, or pinholes. Next, check the wiring for any signs of wear or corrosion like missing insulation or bare wire.

How long does it take for a thermopile to heat up?

The push button must be depressed through the whole check. (With the thermocouple being disconnected from the gas valve, the pilot valve should not stay open and the flame should go out if the push button is released). The thermocouple typically needs to heat up for 30 to 60 seconds in order to obtain a proper reading.

What causes a thermocouple to burn out?

Under constant exposure to a hot flame, a thermocouple wears down over time. Even a slight residue can make the thermocouple malfunction. The fix here is as easy as removing the thermocouple, cleaning it with a wire brush or something coarse (even an ordinary dollar bill works), and replacing.
