  If your Dimplex Indoor Fireplace does not turn on with the remote control, ensure proper operation. Also, the remote control might not be initialized to the fireplace, so initialize it. If that doesn't work, the remote control might be defective. Install a new battery into the remote control and reinitialize the remote where necessary. Lastly, a defective Remote Control Receiver could be the problem, so replace it.

  The Dimplex Indoor Fireplace heater might be turning off after a couple of minutes due to a build-up of dirt/dust in the heater assembly. Ensure that exterior intake louvers and the firebox cavity are free of dirt and dust. Alternatively, the heater assembly could be defective. Replace the heater motor if it's not running when heat is activated, or replace the heater elements if the motor is running but heat isn't coming out.

  If your Dimplex Indoor Fireplace is making excessive noise when the heater is on, it could be due to a dirty blower assembly. Make sure that the exterior intake louvers and firebox cavity are free of dirt and dust. Another potential cause is a defective heater motor, which would need to be replaced.

Why does my Dimplex Indoor Fireplace unit turn on and off by itself?
- M
  Mary FergusonAug 29, 2025
  Your Dimplex Indoor Fireplace might be turning on and off by itself because the remote control has a similar frequency to other remotes in the area; try replacing the remote control. Radio frequency disturbance from outside sources could also be the reason; in this case, replace the remote control and the Remote Control Receiver Kit, where necessary. A defective Remote Control Receiver could also be the culprit; replace the Remote Control Receiver.

  Small glowing sections of the heating element in your Dimplex Indoor Fireplace are considered normal. However, if larger glowing sections are causing the heater to trip the thermal cutout, unplug the unit, discontinue use, and replace the heater elements.

  Mario BurchSep 5, 2025
  If your Dimplex Indoor Fireplace does not turn on manually, it might be due to improper operation. There might be no incoming voltage from the electrical wall socket/Breaker Panel, so check the Fuse/Breaker Panel. Another reason may be loose wiring, so check wiring connections. It could also be a defective On/Off Switch, a defective Heater Switch, or a defective Remote Control Receiver (if applicable), so replace them if needed.
