While your Lennox® heater cannot speak to you, it does have a method to get your attention when there’s a furnace error.
Its control panel has double LED lights that can display a fault code. Subject to the fault, your furnace might use steady or flashing lights.
Although there are a few basic HVAC repairs you can finish yourself, many services are best taken care of by HVAC technicians. When your heating system will not start or put out warm air, reach out to House of Heating Incorporated at 715-384-3163 for skilled furnace repair in Marshfield.
Our specialists will swiftly identify and fix the breakdown, even if you don’t have a Lennox heater. We can service all brands or models—and get the heat returned to your residence quickly.
What Does the Blinking Light on My Heater Mean?
Your heating system uses lights to flash code when it is malfunctioning. It also works this system to tell you it’s heating like it should.
Normal function consists of:
- Concurrent slow flash—heating system running like it should.
- Both lights flash fast—heating system is initiating the call for heat.
If you see a lone light flashing slowly and the other going on and off quickly, your heater could be experiencing a low flame signal. This can occur even when your heater is working correctly. It signifies the flame sensing rod could need to be cleaned or in the wrong area on the burner. Contact us at 715-384-3163 for support.
Here are a few other of the most common errors for Lennox heating systems.
