What Does the Blinking Light on My Heating System Mean?
Your heating system depends on lights to flash code when it requires repairs. It also works this system to relay it’s working properly.
Correct operation consists of:
- Both lights flash slowly—heater heating like it should.
- Both lights flash fast—heating system is beginning to call for heat.
If you notice a solitary light blinking slowly and the other going on and off fast, your heating system may have a low flame signal. This can take place even when your heater is heating properly.
