Questions and Answers

Why does my Dimplex RLG20 trip the circuit breaker?
- R
  russoangelaAug 21, 2025
  If your Dimplex Indoor Fireplace trips the circuit breaker or blows a fuse when turned on, it could be due to a short in the unit's wiring. You may need to trace the wiring in the unit to identify and fix the short. Alternatively, too many appliances on the same circuit might be exceeding its current rating. Try plugging the unit into a different outlet or installing it on a dedicated 15 amp circuit.

  Marcus PenaAug 27, 2025
  If your Dimplex Indoor Fireplace heater emits an odor, it's likely normal, especially when the heater is initially turned on. This is due to the burning off of dust accumulated during manufacturing or operation. However, if the odor persists or is concerning, the heater assembly might be defective and require replacement.
