    Why does my Dimplex SF3003 keep tripping the circuit breaker?
    • E
      Erik HernandezAug 21, 2025
      If the circuit breaker trips or a fuse blows when you turn on your Dimplex Indoor Fireplace, it could be due to a short in the unit's wiring, in which case you should trace the wiring. Alternatively, additional appliances might be exceeding the current rating of the circuit breaker or fuse. Try plugging the unit into another outlet or installing it on a dedicated 15 amp circuit.

      If the heater fan on your Dimplex Indoor Fireplace turns on but doesn't produce heat, first, refer to the Operation Section for proper operation. Check for loose wiring in the unit. It could also be a defective Heater Assembly, which would need to be replaced.

      If the lights dim in the room when your Dimplex Indoor Fireplace is on, the unit might be drawing close to the circuit's current rating. Try moving the unit to another outlet or installing it on a dedicated 15 amp circuit.

      If your Dimplex Indoor Fireplace heater emits an odor, it may be normal if it's a brief period after the heater is initially turned on, as it burns off dust accumulated during manufacturing or operation. However, a defective Heater Assembly could also be the cause, requiring replacement.

      If your Dimplex Indoor Fireplace isn't turning on manually, first, refer to the Operation Section for proper operation. Check the Fuse/Breaker Panel to ensure there's incoming power from the electrical wall socket. Also, inspect wiring connections for any looseness. A defective switch (3-Position or On/Off) or a defective Remote Control Receiver could also be the problem, requiring replacement.

    • N
      Nancy PhillipsAug 28, 2025
      If the heater on your Dimplex Indoor Fireplace turns off after a few minutes, it could be due to a buildup of dirt or dust in the heater assembly. Ensure the exterior intake louvers and firebox cavity are free of dirt and dust. Alternatively, the Heater Assembly may be defective and require replacement.

    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.

      If your Dimplex Indoor Fireplace isn't turning on with the remote control, ensure the remote is initialized to the fireplace. If not, initialize the remote control.
