What Does the Flashing Light on My Heater Mean?
Your furnace uses lights to flash code when it needs to be repaired. It also works these lights to relay it’s heating like it should.
Normal heating consists of:
- Both lights flash slowly—heating system heating correctly.
- Simultaneous fast flash—furnace is starting to call for heat.
If you see a single light going on and off slowly and the other going on and off rapidly, your furnace could be having a low flame signal. This can take place even when your heater is heating properly. It means the flame sensing rod may need to be cleaned or in the incorrect area on the burner. Contact us at 308-321-4703 for support.
Here are several other of the most typical errors for Lennox HVAC systems.
Heater Refuses to Kick On
Here are many of the light arrangements you may see when your heater refuses to or stay on. The majority of these problems must be taken care of by a specialist, like one from Jack's Heating, Cooling, Stoves & Fireplaces.
- All LED lights aren’t lit. This signifies your furnace might not have electricity. Find the breaker box to confirm the heating system fuse is not tripped. Attempt to reset the fuse if it is in the “off” area. If it rapidly flips after you reset it, leave the breaker alone and contact us at 308-321-4703.
- A single light is unchanging and the other is blinking slowly. This signifies the flame rollout switch is probably open. The switch is an essential safety mechanism that assists in preventing fires and carbon monoxide. You shouldn’t seek to handle this fault yourself.
- One light is flashing quickly and the other is blinking slowly. This usually indicates power polarity has been transposed. Your furnace may have a wiring fault that requires specialized support from Jack's Heating, Cooling, Stoves & Fireplaces.
- Both lights are flashing slowly. This indicates your furnace’s blower motor probably isn’t working. This piece circulates warm air from the HVAC system into your space. We can help in figuring out what’s wrong with this piece.
- One light is flashing slowly and the other is flickering quickly. This indicates your heater might have insufficient voltage or a short circuit. Get in touch with our experts at 308-321-4703 for support.
- One light is flashing on, on and off while the other flickers on, off, on. This means there may be an error with your heater’s control board or wiring. Jack's Heating, Cooling, Stoves & Fireplaces can find the error and take care of it.
- The pair of lights are using alternate slow flickers. This signifies your furnace may have a flame failure. There could be a problem with its gas supply, gas valve or ignitor control. Contact us at 308-321-4703 for assistance.
- An individual light flickers slowly while the other stays continuous. This typically signifies your furnace’s limit switch is not working. The switch stops your HVAC equipment from becoming too warm. Get in touch with the experts at Jack's Heating, Cooling, Stoves & Fireplaces for assistance.
Heating System Blower Operates But No Warmth
Here’s what may be wrong when you observe your heater’s blower fan on, but you aren’t gaining any warm air.
- The pair of lights are giving alternate quick flashes. This signifies your furnace ignitor could not be working. This component lights fuel in your heating system to make warmth and should be repaired by a specialist from Jack's Heating, Cooling, Stoves & Fireplaces.
