Question: How Do You Remove A Thermocouple From A Fireplace?

Step-by-Step Procedure To Replace A Gas Fireplace Thermocouple

  1. Step 1: Use a wrench tool to unscrew the connector.
  2. Step 2: Unhook the probe from its clip.
  3. Step 3: Take the removed thermocouple to the hardware store.
  4. Step 4: Replace the new thermocouple with the help of a probe.

How do you remove a thermocouple from a gas fireplace?

The only tool you need to replace a thermocouple is a wrench. Turn off the gas supply to the gas valve. Use the wrench 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.

Can you disconnect a thermocouple?

The thermocouple is usually attached to the pilot gas supply tube with one or more clips that snap into place. The end of the thermocouple is inserted into the pilot assembly and can simply be pulled out. Take the detached thermocouple with you to the home center or hardware store and buy a new one.

How do I know if my thermocouple is bad on my gas fireplace?

Light the pilot and observe the quality and size of the flame. It should be mostly blue, burn steadily and be large enough to engulf the thermocouple probe. If it’s yellow or orange, undersized and unsteady, the pilot tube is probably clogged, and it needs to be cleaned.

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.

Can I replace a thermocouple myself?

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.

Can you clean a thermocouple?

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.

Should thermocouple be in pilot flame?

If the pilot light goes out, the thermocouple detects it and shuts the valve supplying gas to the pilot. The pilot flame should touch the thermocouple at a specific level. If the flame covers the top of the thermocouple and burns steadily with a yellow tip, that’s just about right.

What causes a thermocouple to go bad?

Changes in temperature can cause regular expansion and contraction in metal, which will cause thermocouples to weaken over time. After enough time, metal fatigue can cause a thermocouple to break. If thermocouples start to give out unusual readings, it may be suffering from metal fatigue.

How do you troubleshoot a thermocouple?

Select the ohms or resistance option on your multimeter. Place one test lead on the side of the thermocouple and the other to the end that screws into the gas valve. If the thermocouple has proper continuity, a small resistance reading should be visible on the multimeter.

How long does a thermocouple last on a gas fireplace?

Thermocouples are rigorously tested and should last for years. Indeed, experts believe a four-year check cycle is all that is needed to make sure things are functioning properly.

Do Thermopiles go bad?

Like the other component parts in your furnace, the thermocouple can wear down over time, producing lower voltage than it should when heated. And the worst part is that you can have a bad thermocouple without even knowing. Therefore, inspecting and testing your thermocouple should be part of your furnace maintenance.
