Why is the heater not turning on in my Dimplex Indoor Fireplace?
- MMr. Michael KnightSep 2, 2025
If your Dimplex Indoor Fireplace heater is not turning on, but the flame effect is still functioning, ensure proper operation. If the issue persists, there could be loose wiring, which requires tracing the wiring in the unit. Other potential causes include a defective switchboard, heater assembly, or display/control board, all of which would need to be replaced.
