FIXED: Heat N Glo Remote Control Not Working

The Quick Answer: Why Your Heat N Glo Remote Isn't Working

If you're freezing and just want the fire on right now, here is the immediate fix. The problem is almost certainly the batteries in the receiver box.

Most people change the batteries in the handheld remote and get frustrated when nothing happens. But there is a black control box (the receiver) hidden underneath your fireplace insert behind the bottom louver or grate. That box has 4 AA batteries in it. If those are dead, the remote can't talk to the fireplace. Change those, flip the switch to "REMOTE," and you're usually good to go.

The Full Guide: Troubleshooting Your Heat & Glo Fireplace

Hey! So, its that time of year again. You went to turn on the cozy gas fireplace, pressed the button, and... silence. Nothing. Maybe a faint clicking sound if you're lucky, but usually just frustration. I've been there a dozen times.

I’ve helped a ton of friends fix this exact issue, and honestly, you rarely need to call a technician. A service call can cost you $150 just for them to show up and swap some batteries. Keep your money. I'm gonna walk you through this step-by-step.

Step 1: The "Hidden" Batteries (The Receiver)

Okay, this is where everyone gets tripped up. Your Heat N Glo system has two parts: the transmitter (the remote in your hand) and the receiver (the brain inside the fireplace).

You probably already changed the batteries in the hand-held remote. If the screen is on, those are fine. The issue is the receiver.

How to find it:

1. Go to your fireplace.
2. Look at the bottom metal grill or louver (under the glass).
3. Most of these flip down or lift off. It might be stiff if you haven't opened it in a year.
4. Look for a black plastic box. It usually has a slider switch that says ON - REMOTE - OFF.

That box has a battery cover. Slide it off. It usually takes 4 AA batteries. When these batteries get weak, they might have enough power to make a "beep" sound but not enough juice to actually open the gas valve. Swap them out with high-quality alkalines (Duracell or Energizer). Don't use the cheap heavy-duty ones, they don't last long enough in the heat.

Step 2: The Slide Switch

While you are down there looking at that black box, look at the switch. It needs to be in the REMOTE position.

• ON: This overrides the remote and turns the burner on manually. Use this if you lost your remote and just want heat.
• OFF: This cuts power to the remote receiver. Nothing will work.
• REMOTE: This is where it needs to be for the handheld unit to work.

Sometimes when cleaning or vacuuming near the fireplace, this switch gets bumped into the OFF position. Just slide it back to the middle.

Step 3: Re-Syncing (Pairing) the Remote

This is the second most common fix. Even if you put new batteries in, the receiver might have "forgotten" the remote. It happens. You need to re-introduce them.

The process is slightly different depending on if you have the older standard remote or the newer touchscreen ones (like the RC300 or RC400), but the logic is the same.

For most standard remotes:

1. Locate the receiver box (the one you just put batteries in).
2. Find the small hole or button labeled "LEARN" or "PRG".
3. Use a paperclip or pen tip to press and release that button quickly. You should hear a distinct BEEP from the box.
4. Immediately (within a few seconds) press the ON button on your handheld remote.
5. The receiver box should beep again (usually a couple of rapid beeps) to confirm it heard the signal.

If you heard the second set of beeps, congrats! You just fixed it.

Step 4: Check Thermostat Mode

This one makes you feel a little silly when you realize it, but I've done it too. Look at your remote's screen.

Does it say "THERMO" or show a temperature setting? If your remote is in Thermostat mode, it acts like the thermostat on your wall for your furnace. If you have it set to 70 degrees, and your living room is currently 72 degrees, the fireplace will not turn on.

It thinks it's doing a good job by not overheating you. To test if this is the problem, simply switch the remote to "Standard" or "Manual" mode (usually by hitting the mode button until the temperature disappears), or crank the set temperature up to 90 degrees to force it on.

Step 5: Battery Corrosion

Since the receiver box sits under the firebox, it gets warm. And then it gets cold. And it sits there for months during the summer unused. This environment is notorious for causing batteries to leak.

Pull the battery holder out of the receiver. Look at the metal springs and contacts. Are they shiny silver? Or do they have that crusty white or blue powder on them? That's battery acid corrosion.

If you see the crusty stuff, the electricity can't flow. You don't necessarily need a new box though.

How to clean it:

• Get a Q-tip and dip it in white vinegar or lemon juice.
• Scrub the contacts. The acid in the vinegar neutralizes the battery leakage.
• Wipe it dry with a paper towel.
• Use a pencil eraser to rub the contacts until they are shiny again.

I fixed my neighbor's "broken" fireplace last winter just by scrubbing the contacts. Saved him $200 on a new receiver kit.

Advanced Troubleshooting: When It's Not the Batteries

Okay, so you changed the batteries, you cleaned the contacts, and you tried to sync it, but it's still dead. Let's dig a little deeper.

The "Lockout" Safety Feature

Heat N Glo fireplaces (and many other brands like Majestic or Quadra-Fire) have safety protocols. If the fireplace tries to light but fails to sense a flame multiple times, it goes into "Lockout" mode to prevent filling your house with gas.

To reset a lockout, you usually need to completely cut power to the unit.

If your fireplace is battery-only, take the batteries out of the receiver box for about 5 minutes. If your fireplace has a fan (blower) that plugs into the wall, you might need to flip the circuit breaker for the fireplace off for a minute, then back on.

Static Electricity and Interference

Believe it or not, according to some HVAC manuals, RF (Radio Frequency) remotes can get confused by other devices. Do you have a new baby monitor? A new WiFi router right next to the fireplace? Sometimes signals cross.

Try moving the receiver box slightly (it's usually on wires that have a little slack) to see if the reception improves.

The Pilot Light Issue (IPI vs. CPI)

Does your fireplace have a standing pilot (a little blue flame that is always on)? Or does it spark and light up every time you turn it on?

If you have a standing pilot: Check if the pilot light is actually lit. If the wind blew it out, the remote can't turn on the main burner. You'll need to follow the instructions on the metal tag under the fireplace to re-light the pilot manually.

If you have an electronic ignition (IPI): These systems spark to light the pilot only when you call for heat. If you hear clicking but no flame appears, you might have a gas supply issue or a dirty pilot assembly. If you hear no clicking at all, it's likely still an electrical/remote issue.

Is It Time for a New Remote?

Sometimes, electronics just die. The capacitors inside the receiver box can dry out over 10-15 years. If you've done the batteries, the cleaning, and the syncing, and the manual slide switch works (turning the fire on manually), then your remote system is probably toast.

You can buy replacement kits online. You don't always have to buy the official Heat N Glo branded one (which can be pricey). Skytech makes a lot of the remotes for these fireplaces. You just need to make sure the plugs match your gas valve.

Warning: If you aren't comfortable with wires, this is the point where you call a pro. Gas isn't something to mess around with if you're guessing.

Preventing This Next Year

To avoid this headache next winter, here is a pro tip: Take the batteries out of the receiver box when spring comes.

I know, its a pain to get down on the floor and open the grate. But leaving alkaline batteries in a hot environment for 6 months while not using them is the #1 cause of corrosion. Just toss them in a drawer and put fresh ones in when the first frost hits.

Frequently Asked Questions

Why is my fireplace beeping but not lighting?

If the receiver beeps when you press the remote, it means it's getting the signal. That's good! If it doesn't light, it usually means the batteries in the receiver are too weak to open the valve solenoid (which takes more power than just making a beep sound), or the gas supply is off.

Can I use a universal remote for my Heat N Glo?

Generally, no. You can't just use a TV remote. However, there are "universal" fireplace remotes made by companies like Skytech or Ambient that are compatible with the millivolt valves used in Heat N Glo units. You have to replace the whole kit (remote and receiver), not just the handheld part.

What does "IPI" mean on my switch?

IPI stands for Intermittent Pilot Ignition. It means the pilot light goes out when you turn the fireplace off to save gas. CPI stands for Continuous Pilot Ignition (or Standing Pilot). In the dead of winter, switching to CPI is actually better-it keeps the chimney warm so you don't get cold air drafts, and it keeps the glass condensation-free.

My remote has a "Child Lock." How do I turn it off?

This happens to the best of us. On many Heat N Glo remotes, if you see a padlock icon, the buttons won't work. Usually, you have to press the "Up" and "Down" arrows at the same time, or the "Mode" and "Up" button. Check the back of the remote, sometimes the cheat code is printed there.

Does the receiver box need to be plugged into a wall outlet?

Not usually for the fire to light. The flame part runs on the AA batteries (or the pilot generator). However, if you have a blower fan that pushes air into the room, that needs 120V wall power. The remote turns the fire on, and a heat sensor usually turns the fan on automatically once the box gets hot.

Hope this helps you get warm! If you try all this and it still won't light, go check the gas valve on the wall or outside-you wouldn't believe how many times someone accidentally bumped the main gas lever off.
