Why does my gas fireplace not light sometimes?
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 does my gas fireplace take so long to ignite?
Short cycling of propane fireplaces can cause ignition problems that mimic delayed ignition. Unburnt fuel pools at the bottom of the firebox after the burner cycles off and, if the fireplace is turned back on before the fuel dissipates, the pooled fuel will light off rather loudly.
How do you clean a thermopile?

What do I do if my pilot light won’t light?
If your pilot light won’t stay alight, it might be the thermocouple. Sometimes dust buildup collects on the thermocouple and blocks the sensor. Try cleaning the thermocouple and then relighting the pilot light. If it continues to go out, the thermocouple might need to be replaced.

Quote from Youtube video: It has a copper wire that screws into the gas valve that's the way to spot the difference between a thermocouple. And a thermo-pile not all fireplaces have both some just have the thermo-pile.
How long does a thermopile last?
Thermopile sensors don’t have a specific life expectancy or degradation rate. As long as they are used correctly and maintained properly, thermopiles can last for years or even decades and remain in good working condition.
What are the symptoms of a bad thermocouple?
Failed Thermocouple Symptoms
- Signs of contamination on the tube, e.g. discoloration, cracks, or pinholes.
- Signs of wear or corrosion of the wirings, e.g. missing insulation or bare wire.
- Physical damage to the connectors which can have an effect on the reliability of the test reading.
How much does a thermocouple cost?
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.
How long does a thermocouple last on a gas fireplace?
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.
Does cleaning a thermocouple help?
