# Gas Fireplace Not Working? How to Troubleshoot the 4 Most Common Problems
Gas fireplace not working? Houston’s Top Gas Fireplace Services walks you through 4 of the most common problems — pilot issues, electronic ignition failures, and remote problems, with step-by-step fixes
If your gas fireplace is not working, you’re not alone. Pilot light issues, electronic ignition failures, and unresponsive remotes are some of the most common service calls we get at Top Gas Fireplace Services across Houston, Cypress, Katy, Spring, and The Woodlands.
The good news: many gas fireplace problems have simple fixes you can try yourself in a few minutes — before paying for a service visit. This gas fireplace troubleshooting guide walks you through the four most common issues homeowners run into, and exactly what to check first.
> **A quick safety note:** If you smell gas at any point, stop immediately, turn off the gas supply at the shutoff valve, leave the home, and call your gas utility. The steps below assume your fireplace is otherwise in normal working condition and you’re comfortable with basic checks. When in doubt, call a licensed gas fireplace repair technician.
Why Is My Gas Fireplace Not Working?
Most gas fireplace problems fall into one of a few categories: pilot light or thermopile issues, electronic ignition failures, grounding problems, gas supply interruptions, or remote control pairing errors. Identifying which category your problem falls into is the first step in figuring out whether it’s a quick fix or a service call.
Here are the four problems we see most often in Houston homes.
Problem 1: Pilot Light Is On, but the Gas Fireplace Won't Light
This is one of the most common issues with millivolt (standing pilot) gas fireplaces. You can see the pilot flame burning steadily, but when you flip the wall switch or remote, the main burner won’t ignite.
Most Likely Cause: A Stuck Solenoid in the Gas Valve
Over time, the small solenoid inside your gas valve can get sticky or partially jammed — especially in fireplaces that sit idle through the spring and summer months. Houston’s humidity doesn’t help. Fortunately, the fix is simple:
- Confirm the pilot is lit and the wall switch is in the ON position.
- Give the gas valve a few light taps with the handle of a screwdriver or your knuckles. Nothing forceful — just enough to free up the stuck solenoid.
- Listen for the main burner to ignite within a few seconds.
If that worked, great – your fireplace is back in business.
Still Not Working? Check the Wall Switch
If tapping the valve doesn’t solve the problem, the next likely suspect is the **wall switch itself**. Wall switches wear out over time, and a faulty switch is one of the most common reasons a gas fireplace pilot stays lit but the burner won’t fire.
We don’t recommend testing the switch yourself, the low-voltage wiring connects directly to your gas valve, and a wiring mistake can damage the valve or create a safety issue. A technician can test and replace the switch in about 15 minutes.
If neither the solenoid nor the switch is the culprit, you may be dealing with a weak thermopile, a clogged pilot orifice, or a failing gas valve. All three require professional diagnosis
Problem 2: Electronic Ignition Gas Fireplace Won't Turn On at All
If you have an electronic ignition gas fireplace and absolutely nothing happens when you flip the switch or press the remote – no clicking, no spark, no sound – the problem is almost always a **power supply issue**.
How to Test for Power
Here’s how to confirm whether your fireplace is getting electricity:
1. Locate the outlet your fireplace’s ignition module is plugged into. This is usually behind the unit or in a nearby cabinet or junction box.
2. Plug something else into that outlet, a phone charger, a lamp, or any small device you can see working.
3. If your test device doesn’t power on, the outlet is the problem. Check your breaker panel for a tripped breaker and reset it.
If the Outlet Has Power, the Ignition Module May Be Faulty
If the outlet is working but your gas fireplace still won’t respond, the next likely suspect is the **ignition control module**. Modules can fail with age, heat exposure, or power surges, common in older Houston homes without surge protection.
Replacing an ignition module is a job for a gas fireplace technician. Modules are matched to specific units and need to be wired correctly to avoid damaging the valve or creating a safety hazard.
Problem 3: Gas Fireplace Clicks but Won't Light
This one fools a lot of homeowners. You can hear the igniter clicking away, you might even see a small spark — but the fireplace never actually lights.
Most Likely Cause: A Grounding Issue
Electronic ignition systems need a proper ground to detect that a flame has lit. If the ground wire has come loose or was never connected properly, the system will keep clicking and sparking but won’t open the gas valve.
Look behind the unit for a **black ground wire**. It should be securely attached to a grounded metal surface — typically the burner assembly or a designated grounding screw on the firebox. If you find it disconnected or loose, reattach it firmly and try again.
If the ground wire is properly attached and you’re still getting clicks without ignition, the issue could be:
– A worn-out igniter
– A dirty or corroded flame sensor
– A faulty ignition module
– A gas supply problem
All of these require professional diagnosis.
Problem 4: Gas Fireplace Remote Not Working After New Batteries
You replaced the batteries in your remote (and the receiver, if it takes them too), but the fireplace still won’t respond.
### Most Likely Cause: The Remote Needs to Be Re-Paired
When the receiver loses power, even briefly during a battery swap, it can lose its pairing with the remote. Re-pairing is usually a 30-second job:
1. Locate the receiver box. It’s often behind the fireplace, inside a control cabinet, or under the unit.
2. Find the small **pair button** or **learn button** on the receiver. It’s usually labeled and recessed.
3. Press and hold it until you hear a beep or see an LED change.
4. Within a few seconds, press any button on the remote (most systems prefer the ON button).
5. Listen for a confirmation beep.
Different remote brands > Skytech, Mertik Maxitrol, Proflame, and others — have slightly different procedures. If you have the manual handy,
follow those specific instructions. After re-pairing, your remote should control the fireplace normally.
If re-pairing doesn’t work, the receiver itself may have failed and need replacement
When to Call a Gas Fireplace Repair Technician
DIY troubleshooting is great for ruling out the simple stuff, but gas appliances aren’t something to gamble with. Call a licensed gas fireplace repair technician immediately if:
– You smell gas at any point
– The pilot light won’t stay lit
– You see soot buildup, yellow flames, or rust on the burner
– The glass front is cracked
– The fireplace lights but won’t stay running
– You’ve tried the steps above and the issue persists
Annual gas fireplace inspection and cleaning also prevents most of these problems before they start. We recommend a yearly inspection for all Houston-area gas fireplaces — humidity, dust, and seasonal use take a toll on these systems.
