Get fired up and ready to go! Installing a fireplace in your home can boost your home’s value by up to $12,000. A fireplace can be a great resource to keep your house warm and entertain your friends.
However, you cannot just install a fireplace and let it sit there. A broken fireplace will not increase your home value. Get smart about fireplace repair and learn how to fix a gas fireplace wall switch.
What are wall switches, and what are the most common problems with them? How can you replace a switch? Can you replace a faulty wire yourself?
Answer these questions and you can have a beautiful high-tech fireplace for years to come. Here is your quick guide.
Understand How a Gas Fireplace Wall Switch Works
In order to fix a wall switch, you need to know how a wall switch functions. A gas fireplace pilot light administers heat to a thermopile, which generates the electricity needed to light your fire. When you flick a switch, the electricity travels from the thermopile to your gas valve, igniting the fire.
A malfunctioning switch will not create a strong current of electricity. Yet your pilot light, thermopile, and gas valve may work fine.
Do not panic if your wall switch does not turn your gas fireplace on. Remove the cover plate over your wall switch with a screwdriver. Then use your screwdriver to remove the screws that attach your switch to the wall.
Take a look at the wires attached to your switch. They should be thin, not thick.
If they are thick, you may have unscrewed the wrong switch. Screw this switch back into place and try to find the one for your fireplace.
If you have found the right switch, you should unscrew the wires connected to the switch. Touch the wires together and twist them while wearing a pair of rubber gloves.
You should try turning the fireplace on. If it does, you have discovered that you have a faulty switch. You should pursue switch repair tips so you do not encounter a similar problem in the future.
If it does not, you have a problem with another part of your fireplace. Call your installer for help and ask for gas fireplace tips.
Replace the Switch
To replace your faulty switch, you need to buy a millivolt switch. Fireplaces do not use a high amount of voltage, and high surges can damage your switch. A millivolt switch can handle the right amount of voltage and electric current without breaking down.
You can buy a millivolt switch from online retailers and fireplace stores. Make sure the switch is the right size and can attach itself to the wires in your fireplace.
Turn off your fireplace before you begin replacing your switch. If you have not removed your old switch, you should do so.
Then connect the wire leads to the terminal screws attached to your new switch. You may need to twist the ends of the wires so they fit inside your screws.
Set your switch into the wall and test it to see if it works. If it does not work, you should get another switch.
Clean up the Wiring
If your switch seems to work fine but has occasional problems igniting your fire, you may need to replace the wiring. Turn off the electricity running through your fireplace, then unscrew the switch cover plate and your switch. Use a flashlight and look at the wires connected to your switch to see if they are loose.
Your wires may be too long, causing them to sag. They may also be tangled or dirty.
For wires that are too long, you can twist them to reduce their length by a few inches. Untangle your wires using your fingertips.
You can clean wires using a brush or microfiber cloth to remove dust and debris. If you notice small holes in them, you can use electrical tape to seal the holes.
After you clean your wires, you should clean your gas fireplace to make sure the gas can distribute evenly. Clean the glass with a glass cleaner, then wipe down the interior with a microfiber cloth, removing any debris or dirt.
Replace the Wiring
If your wires are frayed or broken, you should consider replacing your wires entirely. You can call an electrician if you feel uncomfortable doing this by yourself, but you can replace most wires alone.
Your new wire should be identical to your old wire. It’s okay if it is not the exact same product, but it should be the same length and width as your old wire. It should also be able to hold the same amount of current and voltage.
Using a pair of wire cutters, you can cut the damaged wire. Remove much of the old wire as possible, and use pliers to remove any bits still attached to your fireplace. Take your new wire and attach it to the TH and TP terminals on your fireplace control valve.
Snake your wire through the hole leading from your control valve toward your switch. You may need to run it past other wires or parts inside your fireplace.
Connect the end of your wire to the switch using flat screws. Then check if the new wire is working properly.
Fix Your Gas Fireplace Wall Switch
Your gas fireplace wall switch helps electricity pass through different parts of your fireplace. If you flick the switch and nothing happens, you need to do an inspection. Bypass your switch and see if a current flows through your wires.
Odds are, you need to replace the switch and install a millivolt switch. You may need to clean or repair a broken wire. When nothing works, consider replacing your old wiring.
