What Does the Flickering Light on My Heating System Mean?
Your furnace relies on lights to flash code when it requires repairs. It also engages these lights to relay it’s working like it should.
Normal operation consists of:
- Simultaneous slow flash—heater working like it should.
- Concurrent fast flash—heater is starting to call for heat.
If you realize that one light flashing slowly and the other blinking rapidly, your heating system might be having a low flame signal. This can take place even when your heater is running correctly. It signifies the flame sensing rod could have build-up or in the bad location on the burner. Call us at 270-358-3167 for support.
