Gas Fireplace Repair

For the home, kitchen and beyond, Spartherm manufactures appliances that homeowners have come to trust. Even a trustworthy appliance requires occasional maintenance or repair, however.

Propane Tanks & Natural Gas Lines
If your gas fireplace relies on a propane tank, ensure that it is in the on position and delivering gas; there will be a knob on top of the tank that controls this. If turning the knob to the on position doesn’t open the gas flow, contact your propane supplier. The tank may be exhausted.
If you have natural gas lines in your home that provide fuel instead of a propane tank, ensure that they are working properly. If you suspect that there is an issue with them delivering gas to your home, or you suspect that your gas was shut off, call your utility company.

Pilot Light
Pilot lights ignite the gas as it is delivered to the fireplace unit. Pilot lights can be blown out by an interrupted flow of gas or from a strong draft. When relighting it, make sure that you follow the manufacturer’s instructions carefully. Another common issue with ignition is a dirty pilot light orifice, caused by a buildup of soot and dirt.
If you have successfully re-lit your pilot light, ensured that the orifice is clean, and the fireplace still refuses to ignite, there could be an issue with the thermopile, thermocouple, or wiring.

Thermocouple, Thermopile, and Wiring
The thermocouple is a metal probe that controls the gas valve, sensing the temperature and generating electricity to ignite the gas if necessary. Ensure that it is screwed in tightly and in the correct position.
The thermopile, like the thermocouple, is a temperature sensor that generates electric voltage. They are commonly found on newer gas fireplace models in place of a thermocouple. If you have exhausted other solutions and believe you need to test or replace a component like this, make sure the other causes have been ruled out and call a professional to handle it. They will test to ensure your thermocouple or thermopile are working, and fix any loose or inadequate wiring.

Tripped Circuit Breakers
When the electrical wiring in your house has too much current running through it, circuit breakers “trip,” or cut off the flow of power to prevent the circuit from overheating. Check your breaker box and reset any tripped breakers you come across.

Gas Valves
Make sure that your gas valve is open and in the on position to ensure the flow of gas to your fireplace. This should be located in the firebox. If you have an older model, a key in the wall or floor should be nearby.

Old Batteries
Depending on the type of gas fireplace you own, you may have a remote or receiver that run on batteries. If the batteries in either of these are dead, it could prevent your fireplace from igniting. It’s worth testing your batteries to make sure you don’t just need a fresh set.

Thermostat
Make sure that the thermostat is set properly; often, the issue is that the thermostat is set lower than the temperature in the room. Adjusting this to the correct temperature can sometimes solve the ignition problem.
