The thermocouple is a thermally sensitive device that communicates with the gas valve via a modest electrical pulse. It’s installed on top of your gas furnace. Whenever the pilot is on, it transmits an electric signal that maintains the gas valve open. The thermocouple usually lasts for ten years. However, if it malfunctions, the pilot will not light, and the fireplace will not operate.
As a result, a thermocouple is a crucial component in the operation of a fireplace. If it quits running, the fireplace will also cease working. A wrench tool, on the other hand, may easily replace a gas fireplace thermocouple. However, it is recommended that you check your thermocouple prior to replacing it.
Test The Thermocouple Before You Replace
If you can’t light the pilot, the thermocouple may be broken. However, re-testing it with a voltmeter is a smart idea. Configure the meter to measure in millivolts. After that, take two detectors and place one on the metallic copper tube. The gas valve is attached to the pilot aperture via this metallic copper tubing.
Place another sensor on the thermocouple tube junction that connects to the gas valve. Put the pilot’s assistant light on. To warm the thermocouple probe, keep the valve under watch. If your thermocouple is operating, you should see a measurement of 25 millivolts on your voltmeter in less than 10 seconds of the pilot’s start.
If you receive a reading of less than 25 or none at all, your thermocouple has to be replaced. So, how do you replace a thermocouple on a gas fireplace? Read on to find out.
Step-by-Step Procedure To Replace A Gas Fireplace Thermocouple
Step 1: To disconnect the connector, use a wrench tool. Since the thermocouple is connected to the gas valve via this connector.
Step 2: Disconnect the probe from the clamp. Pull off the complete thermocouple setup after that. However, switch off the gas supply line valve before lifting it.
Step 3: Take the thermocouple you removed to the repair shop. There are numerous styles to choose from. Choose something compatible with your thermocouple.
Step 4: With a probe, install the new thermocouple. Replace the probe in the clip and place it at a safe place from the pilot flame. Another end should be inserted further into the gas valve.
Step 5: Check to see if the flame stays bright after lighting the pilot. If the flame doesn’t quite stay lit for an extended period, bring the probe nearer to the flame.
