A gas fireplace that will not light is frustrating, especially on a cold Utah night. The good news is that a lot of the common causes are simple, and a few you can check yourself in a couple of minutes. Here are the usual culprits, what to try, and when it is time to call a technician.
Safety first: if you smell gas, do not try to light the fireplace or flip any switches. Leave the area and call your gas company. Never force a gas appliance that is not working right.
Start with the easy checks
- Is the gas on? Make sure the gas valve to the fireplace is open and your propane tank is not empty.
- Is there power? Many units use electricity for the ignition or fan. Check the switch, the wall outlet, and your breaker.
- Is it in the right mode? A wall switch, remote, or thermostat set wrong will keep the flame off. Confirm the remote batteries are good.
Common causes when it still will not light
- Pilot light is out. On units with a standing pilot, the flame can blow out. Follow the lighting instructions on the unit to relight it.
- Thermocouple or thermopile issue. This safety part senses the pilot flame and tells the gas valve it is safe to open. If it is dirty, loose, or worn, the burner will not stay lit. This one usually needs a tech.
- Dirty pilot or burner. Dust and debris clog the pilot orifice and burner ports, especially after the off-season. Cleaning restores a strong, steady flame.
- Faulty igniter. If you hear clicking but get no flame, the igniter or its wiring may be failing.
- Gas supply or valve problem. A failing gas valve, a closed supply, or low propane will all keep it from firing.
When to call a professional
If the easy checks do not solve it, or if the problem is with the pilot, thermocouple, igniter, or gas valve, it is time for a technician. Gas components have real safety implications, and guessing is not worth the risk. Our techs diagnose and repair ignition, gas flow, and pilot issues quickly so you can get back to a warm room.
Frequently asked questions
Why does my pilot light keep going out?
Often a worn or dirty thermocouple, a draft, or a weak flame. If relighting does not hold, the thermocouple usually needs cleaning or replacement.
My fireplace clicks but will not light. What is wrong?
Clicking with no flame points to an igniter or gas delivery problem. Confirm the gas is on, then have the igniter and valve checked.
Can I fix a gas fireplace myself?
You can handle the basics like the gas valve, power, batteries, and relighting a pilot. Anything involving the thermocouple, igniter, or gas valve should be left to a pro.
Is it safe to keep trying to light it?
No. If it will not light normally, stop. Repeated attempts can let gas build up. If you smell gas at any point, leave and call your gas company.
