7 Dimplex Electric Fireplace Troubleshooting

Here’s a list of the most common issues faced by the consumers of Dimplex Electric Fireplace. 

Troubleshooting 1: Dimplex Remote Control Not Working

Cause: There could be a few possible causes.

  1. Improper operation
  2. An outside source may be causing a radio frequency disturbance.
  3. The batteries could be dead.
  4. The remote may not be initialized with the fireplace.
  5. The remote may need replacement.
  6. The remote receiver could be broken and in need of replacement.

Solution:

See which of the causes is applicable in your case. Eliminate the causes one by one. Reading the user’s manual to see if you are handling the remote correctly, replacing batteries, and checking if there’s any other source causing radio frequency disturbance is easy to do.

If your Dimplex electric fireplace is new, the most likely cause of your remote control transmitter not working is that you haven’t initialized the remote control to the fireplace. 

If you haven’t initialized your remote control, here’s how you do it.

  • Make sure that the power supply through the main service panel is on.
  • You’ll need to access the manual controls. For some models, you’ll have to pull down the grill or remove the glass doors. You may also need to pull out the right-side steel curtain.
  • Find the manual controls.
  • Turn on the main power switch.
  • You’ll find a switch marked as ‘ON’. Press and hold it for 5 seconds.
  • Press the ON button on the remote control. After this, your fireplace remote receiver will be synchronized with the transmitter.

If you have checked the first four causes and your remote is still not working, your remote possibly needs a replacement. After checking with a new remote, you’ll need to replace the remote receiver if the issue is still unfixed.

  • Your heater may have a power switch of its own. If it does, check that it is in the ON position.

How Do You Clean a Dimplex heater?

Here are the steps to clean a Dimplex electric heater:

  1. Turn off the power supply. Wait for the heater to cool. 
  1. Take a clean microfiber duster. Remove loose dust with it.
  1. With a damp sponge, wipe down the surface of the heater. Let the heater dry.
  1. If your heater has a cover, remove it. Use a compressed air duster on the heater’s interior compartment. This will clean the loose dirt as well as any debris that’s in there.
  1. For an uncovered space heater, the process is different. The heater’s vents and slats should be cleaned with the nozzle of the compressed air duster. You can clean out the heating element if needed, by spraying air on it.
  1. Next, take a vacuum that has a brush attached to the hose. Delicately remove dust from the interior of the heater by vacuuming. While vacuuming a space heater, focus on the vents of the heater. Vacuum away all dirt from there. 
  1. Except for coverless electric space heaters, at this stage, you can clean any heater’s interior surface with a damp sponge. After wiping down, let it dry.
  1. If your heater has a cover, vacuum it to clean and use brush attachments to remove dirt from the fins before putting it back on. Use brush attachments to remove dirt from the fins. 

Is It OK to Leave an Electric Fireplace On all Night?

There is no reason why you can’t keep it on except for the following situations:

  • If you are using an extension cord for your fireplace, it isn’t safe to keep it on overnight. 
  • Also, if your fireplace smells a bit weird or isn’t functioning properly, don’t keep it on overnight.

However, it is best practice if you turn it off when you won’t be in the room or will be sleeping. For one thing, it will raise your utility bills a lot. You can save yourself a lot of money and worry if you set your fireplace’s climatic controls at a medium temperature.

In this setting, your fireplace will turn off automatically when your room is adequately heated.

    • Hi Gloria
      Please check if the wiring is loose. If loos, fix it. Then check the flicker motor. If the motor is defective, the flame will be frozen. And finally check the LED driver board. If the board is defective, you will face low flame. Hope, you will get the solution.
      Thanks

  1. Hi I have the clb20n.
    It has stopped working.
    The most it will do is switch on the flame effect for less than a second then it goes off.
    At which time you can see a small glowing red light on the right hand side of the backplate.
    Please help

    • Hi Gary
      Please check your fireplace circuit breaker. When circuit breaker gets tripped, it may happen. The solution is as easy as flipping it back on. After checking the circuit breaker and fuse, move on to other parts of the electric fireplace. Also investigate if there are any loose connections with the cables.

      Hope, you will the solution.
      Thanks

  2. Hello William,
    We purchased a condo that had one of these installed in it, but we can’t seem to get it to produce heat. There’s a wall switch (looking like a light switch) that seems to turn the unit on, and then three individual power switches hidden at the base of this model (one for the lighting effects, one for the fan, and one for something else?). We can turn it on, hear the fan running, and see the fake flames, but feel no heat. I can find a label with the serial number, but no model number.

    The previous owners left us no remote or owner’s manual for it. Do you have any idea what could be wrong or how to troubleshoot it? Thanks.

  3. Should there be an increase in heat produced when the thermostat is increased? It seems to remain the same and I would like more heat!
    I have a just installed a Dimplex Revillusion, model RBF30WC.

      You can get more heat from your electric fireplace by installing a damper cap, running your ceiling fan clockwise and installing tempered windows. Plus, check all insulation and weather stripping and make sure there is leak. Hope, you will get more heat.
      Thanks

  4. Dimplex fireplace: After unplugging it to reset the unit it works for a short time. Then the log is no longer illuminated and the heat stops. The rest of the flame is working. And if you turn the flame off then the heat works

    • Hi Michael
      When the flame on an electric fireplace not working, the bulb can be the culprit. You need to replace the bulb if no flame effects are being displayed.

      Thanks
