Why does my gas fireplace keep shutting off?
Why does my gas fireplace keep shutting off?
Basically, if the oxygen percentage in a room drops, the flame shape is altered by its incomplete combustion. The heat is then removed from the thermocouple, shutting off the gas valve. If the oxypilot becomes blocked with dust or soot, the flame lifts away from the thermocouple or flame sensing electrode.
How to test if a thermocouple is good?
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. Many multimeters also indicate continuity with an audio alert.
Why does my gas fireplace light not stay lit?
My Fireplace Pilot Light Won’t Stay Lit If the pilot light on your gas fireplace won’t stay lit, a very likely culprit is a component called a thermocouple. A thermocouple is a safety device and is a component of the ignition system. Its purpose is to not allow the gas valve to open if the pilot light isn’t lit.
Why does my gas fireplace shut off after a few minutes?
If the gas fireplace shuts off after a few minutes, it’s pretty much always going to be a pilot head issue, or a valve issue. Take note that it’s the pilot head, not the thermocouple. The whole assembly is usually replaced, and they usually come at the same price.
Can a pilot light turn off a gas fireplace?
The pilot light turns on but also ignites the main burner at the same time (regardless of the electric wall switch position). The electric switch does not turn off the main burner regardless of position?? I can turn the main burner off by turning off the pilot light.
How does a gas fireplace work and how does it work?
The thermocouple is a metal rod that sticks out right in front of the pilot itself. It senses if flame is present or not. If the pilot light is lit, it heats up the thermocouple. This opens the gas valve and allows gas to enter the burner ports…and voila, fire!
Why is my gas fireplace not staying on?
Faulty wall switch may be the cause why your gas fireplace won’t stay lit. This is a common problem for most gas fireplaces. Thermocouple and thermopile are directly connected to the wall switch. When your wall switch is flipped on it transmits current that triggers the flame.
How do I Turn my gas fireplace on?
How to Turn on Gas Fireplace with Wall Switch Step 1: Collect the Manual Step 2: Find the Control Panel of Gas Fireplace Step 3: Turn the Knob off Step 4: Open the Supply Valve Step 5: Rotate the Knob to Pilot Step 6: Tap the control knob and ignition button Step 7: Hold the control knob for up to 30 seconds
Why is my furnace pilot not staying lit?
The most common reason the furnace pilot light won’t stay lit. Bad Thermocouple. A furnace thermocouple is a safety feature that regulates gas flow to your system based on whether the pilot light is on. In simple terms, the thermocouple checks to see if your pilot light flame is lit and turns off the gas flow if it senses that your pilot light is off, so you don’t have gas building up in your home.
Why will gas logs not stay lit?
If you can’t keep your gas logs stay lit, likely your pilot light (flame) is poor or that your thermocouple is bad. Check that your flame is blue and check your thermocouple for voltage. These problems could be manifestations of more serious issues.
