How do you replace a thermocouple on a Heat and Glo fireplace?

How to Remove the Thermocouple in a Heat & Glo Fireplace

1. Turn the gas valve on the front of the Heat & Glo fireplace to the "Off" position.
2. Place a sheet or some newspaper on the floor in front of the fireplace.
3. Loosen the nut securing the thermocouple to the rear of the gas valve with a wrench.
4. Pull the end of the thermocouple out of the back of the gas control valve.

Similarly, it is asked, how do you replace a thermocouple on a fireplace?

Procedure for Replacing a Thermocouple The only tool you need to replace a thermocouple is a wrench. Use it to unscrew the connector that holds the thermocouple to the gas valve, then unhook the probe from its clip and pull out the entire thermocouple assembly.

Secondly, how do you know if you have a bad thermocouple? If you can't get the flame to light at all, and you're sure the gas is on, there's probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that's the sign of a thermocouple malfunction.

Similarly one may ask, how much does it cost to replace a thermocouple on a gas fireplace?

A standard replacement thermocouple only costs our customers around 7 to 9 dollars. Of course labor charge of a trip out is 40.00 (still cheap).

Why my fireplace is not working?

Pilot light systems are the most common reason gas fireplaces fail to light, so check the main gas valve to make sure the gas is turned on. It should usually run parallel to the gas line when it is on. The pilot lights, but not staying lit, indicates that the thermocouple is worn out or bad.

How long do thermocouples last?

Thermocouples can last several years, but they don't typically last as long as the furnace itself. If the pilot remains lit, but the main furnace doesn't stay lit, it's time to replace the thermocouple.

Can you test a thermocouple?

MultiMeter Thermocouple Test Procedure First, remove the thermocouple. Secondly, turn on the meter and set it to Ohms. Touch the two leads together from the meter, and you should get a reading close to zero. With the leads apart, you will read infinity.

What does a thermocouple look like?

The thermocouple looks like a piece of metal tubing smaller than a soda straw. To find it, first locate the gas control box. This is the box that the main gas line enters, where you turn the gas on in the furnace. The other end of the thermocouple sits in the flame of the pilot light.

Are all thermocouples the same?

From an operational perspective the thermocouples for a water heater are all pretty much the same. However, there are two variables, the length and the fittings used to install them, see below. A failing thermocouple will not send the correct electrical impulse and the gas valve will not release any gas.

What does a thermocouple look like on a gas fireplace?

The thermocouple on your gas fireplace is a heat-sensitive device that keeps the pilot gas tube open while the pilot is lit. The thermopile is a related device that you should test at the same time -- its function is to open the gas to the burners.

How do you troubleshoot a thermocouple?

Method 1 Turning on the Pilot Light

1. Locate the pilot light controls on the gas valve.
2. Turn the pilot light on for 30 seconds.
3. Release the button to see if the pilot light goes out.
4. Turn off the gas supply to test the thermocouple again.
5. Count to 20 and wait for the pilot light to go out.

How do you test a thermocouple on a gas fireplace?

How to Test a Gas Fireplace Thermocouple

1. Step 1 – Locate Gas Valve and Pilot Assembly. The thermocouple will resemble a long copper wire running between the pilot light and the gas supply valve.
2. Step 2 – Hold Pilot Open to Heat Thermocouple. Push in the control valve and light the pilot flame.
3. Step 3 – Watch Pilot with Main Burners On.

Is it expensive to replace a thermocouple?

Thermocouple Replacement - $20-$150 Calling a professional plumber to install a new thermocouple should only be up to $150. If you do the work yourself, you will only pay the price of the part which is about $20.

Is a thermocouple expensive?

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. Rather than trying to unfasten the thermocouple inside the water heater's burning chamber, it's easier to remove the whole burner and thermocouple assembly.

Does Home Depot sell thermocouple?

Thermocouple/Thermopile - The Home Depot.

How do you troubleshoot a gas fireplace?

To do this, hold the pilot button down for about one to three minutes while the air bleeds out. Step 3. If gas is coming out of the pilot, but it still won't light, the spark igniter could be the problem. Alleyne says to look for and clear out any debris between the igniter and thermocouple.

How do you clean a thermocouple?

Remove Thermocouple from pilot assembly, using steel wool or emery cloth to lightly clean the tip removing any soot or build up that might have accorded due to an improper pilot flame. Using an eraser from a pencil; clean the threads of the nut that connects the Thermocouple to the control valve and then re-tighten.

Why does my pilot light go out when I release the pilot light knob?

The most likely of those is that the thermocouple needs to be replaced. The button you press to light the pilot bypasses the thermocouple. When you release the button, the thermocouple ensures that unburned gas doesn't get released by shutting off the gas when it's not heated by the burning pilot light.

How close should the thermocouple be to the pilot light?

about 1/2 inch

How do you test a thermocouple on a pellet stove?

Use a digital meter set to Millivolts (DC) to test the thermocouple. When testing with a lighter or another heat source, apply heat to the thermocouple in the firepot. If the thermocouple should produce voltage. If the thermocouple does not generate any power, it needs to be replaced.

How do I test my thermostat?

Thank goodness it is much less expensive to replace a thermostat than your central heat and air unit.

1. Check your thermostat to make sure it is in the "On" position.
2. Stand at the thermostat while an assistant stands at the furnace.
3. Raise the thermostat heat settings slowly.
4. Turn off the breaker to your furnace.

What color should the flame on a gas fireplace be?

A healthy gas flame will burn steadily with a yellow or orange. If the flame is not yellow or orange it may be a sign that your gas fireplace needs adjusting or cleaning, which should be done by a qualified technician, such as those we have at Kozy Heat.
