Lennox Error Code E250: Lennox Code E250 - Indoor Blower Communication Error
Warning: The furnace has stopped running due to a communication problem with the blower motor. This requires diagnosis and repair to restore heat.
How to Fix Lennox Code E250
- Step 1: Check the furnace's power switch to ensure it is in the 'ON' position.
- Step 2: Inspect the furnace filter and replace it if it's dirty. A clogged filter can sometimes cause unusual system behavior.
- Step 3: Reset the furnace by turning off the breaker that supplies power to the furnace for about 5 minutes, then turn it back on. This might clear a temporary communication glitch.
- Step 4: If the error code persists after these steps, contact a qualified HVAC technician for diagnosis and repair.
How to Reset Lennox Code E250
- Turn off the furnace power switch, usually located on or near the unit.
- Turn off the circuit breaker for the furnace. Wait 30 seconds.
- Restore power at the breaker and flip the furnace switch back on.
- Set the thermostat to call for heat. If the error code returns after 2-3 ignition attempts, the fault requires repair.
What does E250 mean?
Lennox error code E250 indicates a communication fault between the furnace control board and the indoor blower motor. Basically, the 'brains' of your furnace can't talk to the part that blows air through your vents. This usually means the furnace has shut down as a safety measure, since it can't properly regulate temperature without the blower working.
This communication issue can stem from a few different things, like wiring problems, a faulty blower motor module, or even a problem with the control board itself. Because the blower is responsible for moving heated air throughout your home, this error will prevent your furnace from producing heat until the problem is resolved.
