What does a thermopile do on a gas fireplace?

What does a thermopile do on a gas fireplace?

What is the Difference Between a Thermocouple and a Thermopile? The thermocouple more or less acts like a sensor for gas flow and supplies gas to the pilot light through the gas valve. The thermopile, on the other hand, opens up the gas valve when the fireplaces are turned on.

How do I know if my thermopile is bad?

When you turn the wall switch on, If your meter reads 0 or very low, you know you have a short in your thermopile and you should replace it.

What does it mean when it says thermopile voltage low?

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.

How much voltage does a thermopile generate?

They are also used widely in heat flux sensors and pyrheliometers and gas burner safety controls. The output of a thermopile is usually in the range of tens or hundreds of millivolts.

How much does a thermopile cost?

The No. 1 cause of pilot lights that won’t stay lit is a worn-out thermocouple. It’s easy to replace and a new one costs $5 to $10.

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.

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). It is if you will the LOAD and we can say the thermocouple is the SOURCE.

What is a good reading on a thermopile?

Good reading is 0 to 13 Ohms. If the reading is higher,magnet is defective therefore Change the Valve – Do not try to repair. Good Reading Page 3 Thermopile Millivolt Check Symptom – Intermittent shutdown or main burner will not light with on/off switch.

Are millivolts AC or DC?

Likewise, are millivolts AC or DC? This input terminal is used for both AC and DC millivolt measurements.

How many volts are in a mV?

Millivolts to volts conversion table

Millivolts (mV)	Volts (V)
1 mV	0.001 V
10 mV	0.01 V
100 mV	0.1 V
1000 mV	1 V
