FIXED: remote for fireplace not working

The "Why Won't My Fireplace Turn On" Guide

There is literally nothing more frustrating than sitting down with a cup of coffee, pointing the remote at the fireplace, and getting... absolutely nothing. I’ve been there. Last winter my wife was convinced our fireplace was broken for good, but it turned out to be the silliest little thing inside the bottom panel.

If you are clicking that button and staring at a cold log set, don't call the repair guy yet. Those guys charge like $150 just to show up and change a battery. Seriously.

Most gas fireplace remote systems are actually pretty simple technology. They aren't smart devices connected to WiFi (usually). They are simple radio frequency transmitters. Because they are simple, they break in predictable ways. Let's walk through this together and get your heat back on.

Step 1: The Hidden Batteries (The Real Culprit)

Okay, I know you probably already swapped the batteries in the handheld remote. That's the first thing everyone does. But did you change the batteries in the receiver?

Here is how it works: Your handheld remote talks to a black plastic box located underneath your fireplace insert. You usually have to flip down the bottom metal grate or louver to see it. It might be way in the back, tucked behind some wires.

That box is the "Receiver." It needs power to listen for your remote's signal. Even if your fireplace is hooked up to electricity for a blower fan, the remote receiver usually runs on 4 AA batteries so the fire can work during a power outage. If those batteries die, the receiver stops listening.

What to do:

• Open the bottom access panel of your fireplace.
• Look for a black box about the size of a pack of cigarettes. It usually has a slider switch on it.
• Pop the cover off. It usually takes 4 AA batteries.
• Pro Tip: Check for white crusty stuff (corrosion). If the batteries have been in there for 3 years, they might have leaked. If you see corrosion, clean it off with a little vinegar on a Q-tip before putting new batteries in.

Once you swap those, try the remote again. Honestly, this fixes the problem for almost everyone I talk to.

Step 2: The "Remote / On / Off" Switch

While you are down there on the floor looking at that black receiver box, look at the switch. It usually has three positions:

1. ON: This manually forces the fire to turn on. It bypasses the remote entirely. If you flip this and the fire starts, congratulations! Your gas valve and pilot light are fine. The issue is definitely the electronics.
2. REMOTE (sometimes labeled RS): This is where the switch must be for your clicker to work. If the kids or the dog bumped it into the OFF or ON position, the remote is useless.
3. OFF: This cuts power to the receiver. The remote wont do a thing.

Make sure that switch is firmly in the REMOTE position. Sometimes it gets stuck "between" clicks, so wiggle it back and forth a bit to make sure its seated right.

Step 3: Re-Syncing the Remote (The "Learn" Function)

Sometimes, just like your WiFi router or your Bluetooth headphones, the remote and the receiver stop talking to each other. They loose their "handshake." This can happen if the batteries died slowly or if there was a power surge.

You need to re-pair them. It's usually super easy, but you might need a flashlight.

The Process:

• Find the "Learn" or "Program" button on the receiver box. On some older models, it is a tiny hole you have to poke with a paperclip. On newer ones, it's a small black button.
• Press and release that button quickly. You should hear a distinct BEEP from the box.
• As soon as you hear the beep, press the ON button on your handheld remote.
• You should hear a a second series of beeps (usually a few rapid beeps).

That series of beeps means "Okay, I hear you, we are friends again." Try turning the fireplace off and on with the remote now.

Step 4: Check Your Thermostat Settings

This one makes me laugh because I've done it myself. Many modern fireplace remotes have a "Thermostat" mode and a "Manual" mode.

In Manual mode, you press ON and the fire starts. You press OFF and it stops.

In Thermostat (or Smart) mode, the remote acts like your house thermostat. You set a temperature, say 72 degrees. The remote has a sensor in it that feels the room temperature.

The Trap: If the remote is set to 72 degrees, but your living room is already 74 degrees because the sun is shining in, the fireplace will not turn on. It thinks it's doing you a favor by not making the room hotter.

Look at your remote screen. If you see the word "Smart" or "Thermo," try switching it back to "On" or "Manual" to see if the fire lights up. If it fires right up, nothing was broken-your house was just already warm enough!

Step 5: The Pilot Light Check

If you have fresh batteries, the switch is correct, and the box is beeping when you click, but no fire appears, we have to look at the gas side of things.

The remote does not light the fire directly. The remote tells a valve to open, which sends gas to the main burner. That gas catches fire from the Pilot Light (that tiny blue flame that stays on all the time).

Look inside your fireplace logs. Do you see a little blue flame?
If NO: Your remote cannot work. The pilot light must be lit first. You'll need to follow the instructions on the metal plate under your fireplace to relight the pilot manually.

If YES (The pilot is on but main burner won't light): This gets a little technical. There is a safety sensor sitting in that blue flame called a thermopile (or thermocouple). It generates a tiny bit of electricity-millivolts-that holds the gas valve open.

According to most HVAC experts, if that sensor gets dirty or worn out, it can't generate enough juice to open the big valve when the remote asks it to. Sometimes you can fix this by just cleaning the soot off the little metal rod in the pilot assembly with a piece of sandpaper or a wire brush. If that doesn't work, the sensor might be dead.

Step 6: Dip Switches (For the Old School Units)

If your fireplace is from the early 2000s or 90s, you might not have a "Learn" button. You might have "Dip Switches."

These look like little tiny light switches in a row, usually 4 or 8 of them. You will find them inside the battery compartment of the handheld remote AND on the receiver box.

These switches set the radio frequency. They must match exactly. If switch 1 is UP on the remote, it must be UP on the receiver.
Sometimes, if a neighbor has a similar fireplace, their remote can actually turn on your fire (creepy, right?). If you are having interference issues, try changing the pattern of the switches. Move switch #3 down on both the remote and the receiver. Just make sure they match perfectly.

Step 7: The "Click" Test

We need to figure out if this is an electrical problem or a mechanical one. Here is the ultimate test.

Get down next to the receiver box. Have someone else stand back with the remote.
Tell them to press "ON."

• Scenario A: Silence.
  If you don't hear a click or a beep, the receiver box is dead or the batteries are dead. It's not getting the signal.
• Scenario B: You hear a loud "CLICK" but no fire.
  This is important. The "Click" is the solenoid trying to open the gas valve. If it clicks, the electronics are working! The remote did its job. The problem is inside the plumbing/gas valve. It might be stuck, or the gas supply is off, or the pilot sensor is too weak.

Step 8: Is the "Child Lock" On?

Yes, fireplace remotes have child locks. It sounds crazy, but they do. usually, you will see a little padlock icon on the LCD screen if you have a fancy remote.

To unlock it, you usually have to press a weird combination of buttons, like "Up and Down" at the same time, or the "Mode" button for 5 seconds. You'll have to Google your specific remote brand (like Skytech or Ambient) to find the unlock code, but it's worth checking if the buttons feel unresponsive.

When to Call a Pro

I am all for DIY, but gas is serious business. You should stop troubleshooting and call a technician if:

• You smell gas (like rotten eggs) and the fireplace isn't lit. Turn off the gas supply immediately and leave the house.
• You see soot building up on the outside of the glass.
• The pilot light keeps blowing out every few hours.
• You hear a "boom" or a "whoosh" when the fireplace finally lights up (this is called delayed ignition and it can be dangerous to the glass).

A Quick Note on "Smart" Upgrades

If your remote is totally dead and a replacement costs $150 (which they often do), you might want to look into a smart home relay. I recently helped a buddy replace his old RF remote receiver with a simple WiFi relay switch he got online for like 20 bucks.

Now he turns his fireplace on with Alexa. It requires a little bit of wiring knowledge (connecting two low-voltage wires), but if your receiver box is broken anyway, it's a cool upgrade to consider rather than buying another clunky plastic remote from 1998.

Frequently Asked Questions

My remote screen is blank, even with new batteries. What gives?

If you put fresh batteries in and the screen is still blank, check the metal contacts in the battery compartment. Sometimes they get bent flat and don't touch the battery tip. Use a small screwdriver to gently pry the metal tab out a bit so it makes a solid connection. If that doesn't work, the remote itself is probably fried. Dropping them on hard tile floors usually kills them eventually.

Can I use a universal remote for my gas fireplace?

Generally, no. Fireplace remotes operate on specific radio frequencies that aren't the same as your TV. However, you can buy "universal" fireplace remotes, like those made by Skytech, which come with a new receiver box. You basically unplug the old box and plug in the new one. It's a full replacement, not just a new clicker.

The fire turns on but shuts off after 5 minutes on its own.

This is usually one of two things. 1) Your batteries in the receiver are weak (they have enough power to open the valve, but not enough to hold it open). 2) The remote is in "Thermostat" mode and it senses the room has reached the target temperature, so it shuts off to save you money.

Do I really need the remote? Can I just turn it on by hand?

Yes! almost every gas fireplace has a toggle switch somewhere. It might be on the receiver box (the "ON" switch we talked about), or there might be a wall switch near the fireplace. You don't need the remote to operate the fire, it's just for convenience.

Where is the receiver box located?

It is almost always under the firebox. Most fireplaces have a decorative metal grill or louvers at the very bottom, near the floor. This panel usually folds down on hinges or just lifts off. It's dark under there, so bring a flashlight!
