What Does the Flickering Light on My Heating System Mean?
Your heater depends on lights to flash code when it isn’t working right. It also works this setup to let you know it’s heating correctly.
Correct operation includes:
- Both lights flash slowly—heater operating correctly.
- Concurrent fast flash—heater is beginning to call for heat.
If you realize that a lone light flashing slowly and the other going on and off rapidly, your heater may have a low flame signal. This can occur even when your heater is operating like it should. It signifies the flame sensing rod could have build-up or in the bad location on the burner. Call us at 484-646-3363 for assistance.
