Gas Fireplace Not Working? Reset a Tripped Breaker to Power It On

Is your gas fireplace not turning on like it should? It can be frustrating when your fireplace fails to start, leaving you without the cozy ambiance and warmth on chilly evenings. But take heart -- in many cases, there are steps you can take yourself to get your gas fireplace back up and running. Resetting a tripped circuit breaker is one of the easiest and most effective ways to troubleshoot a fireplace that won't start up.

We'll also explain when it's best to call in a professional for fireplace repairs. Read on to learn how to troubleshoot and reset your gas fireplace to resolve most ignition issues.

Reasons Why Your Gas Fireplace Won't Turn On

If you flip the fireplace switch or press the ignition button on the remote but nothing happens, there are several possible culprits:

• Tripped circuit breaker - No power reaching the fireplace
• Faulty igniter or thermocouple
• Clogged or dirty pilot assembly
• Gas line issues - leaks, blockages
• Improperly adjusted pilot light
• Cold chimney flue causing backdrafting

The first thing to check is the easiest to fix yourself - a tripped circuit breaker. Let's look at how to reset the breaker so power flows properly to your gas fireplace system.

How to Reset a Tripped Circuit Breaker for a Gas Fireplace

Like most appliances and fixtures in your home, the gas fireplace requires electricity to operate the ignition system and controls. If the circuit breaker supplying power trips or switches off, it will disable your fireplace.

Resetting the circuit breaker is a relatively simple process:

1. Locate the circuit breaker box, usually in the basement, utility room, or garage. Identify the specific breaker controlling the fireplace.
2. Flip the breaker switch firmly to the "Off" position. Make sure it fully disconnects.
3. Let the breaker sit for a full 60 seconds before flipping it back to the "On" position.
4. Head to the fireplace and test its operation - try igniting it normally by remote or wall switch.

With power restored at the breaker, the fireplace should ignite as usual. If it still fails to start, there may be an issue with the ignition components or gas supply lines.

Breaker Tripping Causes

Why would the circuit breaker trip in the first place? Common causes include:

• Short circuit or loose wire connection
• Overload from adding multiple appliances on the circuit
• Faulty breaker in need of replacement
• Voltage fluctuations and power surges

An electrician can diagnose and resolve the underlying issue if your fireplace breaker continues to trip after resets. But a one-off tripped breaker is usually just a minor blip.

Troubleshooting Igniters, Thermocouples, and Pilot Lights

While a tripped breaker is one of the most straightforward problems, ignition system issues can also prevent your gas fireplace from lighting.

The ignition sequence starts when you flip the switch or press the remote control. An electric igniter creates a spark to light the pilot light, which in turn ignites the main burner. A thermocouple senses the pilot flame, signaling the gas valve to open. If any part fails, the sequence stops and the fireplace won't start.

Faulty Igniter

An igniter gone bad won't create a spark, preventing ignition. Warning signs include:

• Hearing a clicking sound but no spark/flame
• No noise at all when pressing ignition
• Pilot keeps going out

Dirty or clogged igniters can be cleaned with a brush and compressed air. But broken igniters will require professional replacement. Modern electronic igniters last 10-15 years before needing service.

Thermocouple Issues

The thermocouple senses heat from the pilot light flame. If the pilot goes out, the thermocouple triggers the gas valve to cut off fuel flow for safety.

A dirty thermocouple can be cleaned for better operation. Adjusting the pilot flame can also help. But if those steps don't resolve the issues of the pilot going out frequently, the thermocouple likely needs replacement by a fireplace pro.

Cleaning the Pilot Assembly

Dust and debris on the pilot assembly can inhibit ignition. Giving it a good brushing removes soot and improves function:

1. Shut off the gas valve before cleaning.
2. Gently brush the thermocouple, igniter, and surrounding area.
3. Blow away loose dirt with compressed air.
4. Turn gas back on and relight the pilot.

Adjusting the Pilot Flame

A weak, unstable pilot flame can impede ignition. Adjusting the flame height higher for a crisper blue flame can help. There is typically a small screw to turn up the gas flow to the pilot light.

Adjust incrementally and only by 1/4 turns. Monitor the flame size and stability. Only increase height if the flame is too small and flickering.

Checking for Clogs in Burners and Gas Lines

Beyond ignition issues, lack of gas flow can also prevent your fireplace from lighting and operating. Clogged components or leaks in the gas lines are the most likely culprits.

Cleaning Clogged Burner Ports

Small lint and debris particles can build up in the burner ports where flame emerges. Using a soft brush, gently brush out any noticeable dirt in the ports:

• Remove any decorative media over the burners first.
• Use a compressed air can to blow out dislodged particles after brushing.
• Check all burner rows and ports thoroughly.

Testing Gas Pressure and Flow

Technicians use specialized manometers to check the gas pressure and flow to your fireplace. Low pressure can indicate leaks, shut-off valves turned off, or obstructions in the line.

Do not attempt to adjust or test pressure yourself unless you have professional experience. Call for a proper inspection if you suspect low pressure or flow issues.

Inspecting Gas Lines

Visually check the exposed flex connector and pipes for the following:

• Kinks and cracks indicating damage
• Corrosion or rust points
• Soot stains signaling leakage

Immediately shut off gas at the main valve if leaks are present. Call a technician for repairs before using the fireplace again. They can test for leaks using a manometer and replace damaged pipes.

Why You Need a Drafting Chimney Flue

Proper venting up through the chimney flue is vital for gas fireplaces to operate safely and efficiently. Cool flue temperatures can actually prevent ignition due to backdrafting.

How Flues Aid Fireplace Operation

Chimney flues provide crucial ventilation by:

• Letting exhaust gases escape
• Balancing air pressure differentials
• Pulling in fresh combustion air

When a flue is too cold or blocked, it can't properly exhaust combustion byproducts. This creates backdrafting down the firebox, making ignition difficult.

Adjusting the Flue Damper

Check that the flue damper is fully open with no obstructions. Adjusting the damper helps regulate draft strength. Close slightly if wind gusts seem to be forcing exhaust back down.

A fireplace technician can ensure optimal damper positioning. Never fully close the flue when operating the fireplace.

Signs of Chimney Flue Issues

Watch for these symptoms that signal chimney problems:

• Smoke backing up into room
• Unstable pilot or main burner flames
• Soot residue around opening
• Difficulty lighting fireplace

A professional chimney sweep can inspect for blockages, damage, and proper drafting. Repairs like flue lining replacement may be needed in some cases.

When to Call a Professional Fireplace Technician

With common sense precautions, you can troubleshoot many gas fireplace ignition issues on your own. But some problems are best left to the pros. Contact a fireplace specialist for:

• Gas line repairs or replacement
• Broken or damaged ignition components
• Flue inspection and drafting issues
• Electrical problems
• Major repairs beyond basic maintenance

Certified specialists have the tools and expertise to safely inspect, diagnose, and fix other fireplace malfunctions you may encounter.

Finding a Qualified Fireplace Technician

When hiring a fireplace pro, look for:

• Certifications such as NFI, CSIA, or CSIA
• License to service gas appliances
• Liability insurance coverage
• Positive customer reviews
• Experience with your fireplace brand/model

Taking these steps will help find a knowledgeable technician you can trust for any major repairs needed.
