What to do if Nortek B6BM fail to operate?
- LLisa FullerAug 6, 2025
If your Nortek Air Handler fails to operate, there are several things you can check:* Ensure the electric is turned on.* Verify the thermostat is operating properly.* Make sure the blower compartment door(s) are in place.* Confirm the air handler disconnect is closed.* Inspect the circuit breaker for tripping or the control board fuse for being burned open.* Check for any open manual reset switches.* See if the filter is dirty or plugged.* Check if the LED on both control boards is constantly ON.
