What to do if my Dimplex PF3033 Indoor Fireplace shuts off or beeps when the heater is on?

If your Dimplex Indoor Fireplace shuts off or beeps when the heater comes on, it might be due to a power surge interference. Try unplugging the unit for 15 minutes to allow it to de-energize and reset the main control board. Consider installing a power regulator board between the main control board and the heater assembly.
