What Does the Flashing Light on My Heater Mean?
Your furnace depends on lights to flash code when it isn’t working right. It also engages this system to tell you it’s operating correctly.
Regular operation consists of:
- Simultaneous slow flash—heater heating properly.
- Concurrent fast flash—heater is beginning to call for heat.
If you realize that one light going on and off slowly and the other blinking fast, your furnace might be having a low flame signal. This can occur even when your furnace is working correctly. It indicates the flame sensing rod might have build-up or in the incorrect location on the burner. Reach out to us at 209-257-3156 for assistance.
