Troubleshooting Tips for Gas Fireplaces

Modern gas fireplaces are highly efficient and built strong. That doesn’t mean that nothing ever goes wrong. When there’s a problem, it’s important that you know how to solve it or know the right professional to call who can.

Here are some common issues with gas prefab/zero-clearance fireplaces and the best ways to get them back into normal working condition. Many of these issues involve the inability of the unit to start and operate.

Troubleshooting Common Gas Fireplace Issues

A variety of things can cause a gas fireplace to not start. Eight of the most common include:

Dead remote batteries

One of the first things to check.

Tripped power breaker

If other electrical items aren’t working on the same circuit as your fireplace, see if a breaker has been tripped.

Closed or partially open gas valves

You may have closed the valve for the off-season or for some other reason. Manually open the valve, or use the key that came with the appliance.

Empty propane tank

Ensure that your tank isn’t empty before digging into more involved troubleshooting tasks.

Compromised gas line

If there seems to be an issue with the line that brings natural gas to your fireplace, check with your gas utility before doing anything. If all is well from the utility’s end, you may want to have a professional do a thorough gas line inspection and perform the necessary repairs.

Extinguished pilot light

Pilot lights can be blown out. Re-light according to your fireplace’s manufacturer’s instructions. If the pilot light orifice is dirty with soot or dirt, clean it or have a technician do it.

Malfunctioning thermocouple or thermopile

A damaged or loose thermocouple may not generate the electricity needed to ignite the gas. Thermopiles, common in newer fireplaces, function similarly to thermocouples. It’s usually best to have a licensed gas fireplace technician address issues with either of these parts.

Mis-set thermostat

Make sure your thermostat is set correctly. This may be all it takes to get your fireplace working again.

Troubleshooting Other Gas Fireplace Issues

Be on the lookout for these three, potentially more concerning issues, that you may come across.

Smells/odors coming from the fireplace

If your fireplace is new, the smell may be the normal burning of residual factory paints. If you smell gas, there could be a leak in the gas line or a problem with other components. Turn off the gas supply, then contact your gas provider or a local fireplace service company for an inspection.

Strange noises

Gas fireplaces often make a little noise as a normal part of their operation. However, loud and strange noises such as rumbling, grinding or roaring should be checked out by a professional. These noises could point to problems with the pilot light, burner or blower.

Gas logs and fireplaces normally produce very little soot buildup. If you’re noticing an excess of this substance, there may be a problem with air flow because of an improper ratio of gas to oxygen or clogged burners. Your owner’s manual should tell you how to troubleshoot this issue, but when in doubt, be sure to call in an expert.

Hindered air flow also can be caused by obstructions in the chimney flue. This should be checked out by a professional.
