    Is it normal for the heating element in my Dimplex SF3003 Indoor Fireplace to glow red?
    • G
      Gary SwansonSep 9, 2025
      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 assembly.

    Why does my Dimplex SF3003 Indoor Fireplace turn on and off by itself?
    • M
      Marc RichardAug 26, 2025
      If your Dimplex Indoor Fireplace turns on or off by itself, the remote control might have a similar frequency to others nearby. Try changing the frequency of the Remote Control, referring to the Operation Section. Radio frequency disturbance from outside sources could also be the cause, so again, change the remote control frequency. If issues continue, replace the Remote Control and Receiver, and initialize them. A defective Remote Control Receiver could also be the culprit, so replace it and initialize it with the Remote Control.
