How do you test a gas fireplace wall switch?

1. Open the control panel of your gas valve.
2. Locate two terminals called ‘TH’ and ‘TP’.
3. Take a jumper wire, paperclip, or a small insulated wire. Put the bare ends of it to the terminals from the previous step.
4. Try turning on the fireplace as usual. If it works, then a bad wire is confirmed.

How does a gas fireplace wall switch work?

The wall switch sends an electrical signal to your fireplace to open a valve and release the gas for the pilot light to light it. Without power most fireplace valves will not open.

What do you do when your gas fireplace won’t turn on?

Check the Spark Igniter If gas is coming out of the pilot but it still won’t light, the spark igniter could be the problem. You should clear out any debris between the igniter and thermocouple. Blowing compressed air into the pilot area, waiting a couple minutes, then trying again could help to fix the problem.

Why won’t my fireplace turn on when I flip the switch?

What can happen over the years, is that the connections inside the switch can get dirty, corroded, or broken, causing a loss of this voltage at the switch. So by the time the small amount of voltage gets sent back to the fireplace, it is not enough to signal the fireplace to turn on.

Why would a gas fireplace suddenly go out?

If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a “lazy” flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn, makes the gas valve shut off.

How long do gas fireplaces last?

How Long Can a Gas Fireplace Last? Generally speaking, you can get a good ten to fifteen years of use before you need to replace your gas fireplace.

Do all gas fireplaces have a wall switch?

Why does my gas fire not ignite?

Gas fire thermocouple issues If your gas fire doesn’t turn on, it may be because the thermocouple isn’t quite in the right place and therefore, can’t interact with the other components as it should. If the pilot flame sparks but doesn’t stay lit, the thermocouple has likely worn out.

How to fix a gas fireplace?

Pilot Light. Compare gas fireplaces on Amazon or source parts like pilot lights.

Thermocouple. The thermocouple is a small metal rod that intersects the gas valve and the burning pilot flame.

Thermopile. Similar to the thermocouple,a thermopile is a sensor that generates voltage.

How do I light the pilot on my gas fireplace?

Light the pilot on a gas-log fireplace by turning the gas flow knob to the “pilot” setting, holding the knob in and using a match to ignite the pilot. After lighting the pilot, continue to hold the control knob in for about 30 seconds, or the pilot may go out. Once the pilot stays lit by itself, turn the gas flow knob to the “on” position.
