Why does my gas fireplace shut off after 10 minutes?
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.
Why does my propane fireplace keep shutting off?
One of the main reasons why your gas fireplace keeps shutting down is likely due to the pilot light. This is an integral part of a gas fireplace, that kick starts the gas fire. When you turn on the fire, the pilot light button needs to be held in so that it can light the fire.

Why does my gas fireplace not 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.
Do gas fireplaces shut off automatically?
Nearly every new gas fireplace comes equipped with safety features such as a 100% fail-safe shut-off valve. If the pilot flame goes out, the gas flow will automatically turn off. Another safety device is a safety pilot.
How do you clean a thermocouple on a gas fireplace?
How to Clean the Thermocouple in a Gas Fireplace
- Turn off the fireplace gas valve and remove the front panel from the fireplace. …
- Use a can of compressed air to gently blow away any dust and dirt from the thermocouple.
- Wipe away any remaining dirt or soot on the thermocouple with a clean, dry cloth.
How much does it cost to replace a thermocouple in a gas fireplace?
between $150 and $250
When replacing a thermocouple or thermopile with the help of a professional, you can expect to pay between $150 and $250.
Does cleaning a thermocouple help?
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. Cleaning a thermocouple is not a fix for an issue, such as inaccurate readings.
How do you check if a thermocouple is working?
Youtube quote:If I take my wire and attach it to anywhere along the sheets of the probe. I attached to the sheath and I'm getting continuity this is a grounded thermocouple if this was an ungrounded thermocouple.
How long does a fireplace thermocouple last?
Thermocouples can last up to 10 years if properly installed and maintained, while furnaces can last 15-20 years, although either may wear out sooner in multifamily units.
What happens if a thermocouple fails?
Normally when the thermocouple malfunctions or isn’t working, it simply shuts off the gas to your heater. This is important, particularly if the pilot light is out, because it prevents harmful gas from leaking into your home.
How much does a thermocouple cost?

What causes a thermocouple to fail?
A good thermocouple is going to be used, and that can lead to metal fatigue. 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.
