While your Lennox® furnace isn’t able to talk to you, it possesses a process to communicate a furnace error.
Its control panel has double LED lights that can display a fault code. Subject to the malfunction, your heater might display solid or flashing lights.
Although there are a few simple HVAC adjustments you can finish without an expert, most tasks are best left to HVAC technicians. When your furnace refuses to kick on or provide heated air, call Desert Husky HVAC/R Services at 520-416-5415 for experienced furnace repair in Tucson and Phoenix.
Our specialists will speedily identify and take care of the breakdown, even if you don’t have a Lennox heater. We can fix any brands or configuration—and get the comfort returned to your home quickly.
What Does the Flashing Light on My Furnace Mean?
Your heating system depends on lights to flash code when it requires repairs. It also engages this setup to tell you it’s heating properly.
Normal function includes:
- Simultaneous slow flash—heater running properly.
- Simultaneous fast flash—heater is initiating the call for heat.
If you notice a single light blinking slowly and the other blinking rapidly, your heating system could be experiencing a low flame signal. This can happen even when your furnace is operating correctly. It means the flame sensing rod could have buildup or in the bad spot on the burner. Call us at 520-416-5415 for support.
Here are a few other of the most common problems for Lennox heating systems.
Heating System Will Not Start
Here are some of the light arrangements you might observe when your furnace won’t turn on or keep operating. The majority of these errors have to be taken care of by a specialist, like one from Desert Husky HVAC/R Services.
- All LED lights aren’t lit. This signifies your heating system might not have electricity. Go to the breaker box to confirm the heating system fuse hasn’t triggered. Try resetting the fuse if it is in the “off” spot. If it immediately trips after you reset it, don’t touch the breaker and call us at 520-416-5415.
- A single light is continuous and the other is flashing slowly. This implies the flame rollout switch is possibly not working
