      If your Nordyne Air Handler isn't working, start by ensuring the power is on and the thermostat is properly set. Make sure the blower compartment door(s) are correctly in place and the air handler disconnect is closed. Check the circuit breaker to see if it has tripped, or the control board fuse to see if it has burned open. Also, verify that any manual reset switches are not open and that the filter isn't dirty or plugged. Finally, check that the LED on both control boards is constantly ON; if not, refer to Tables 3 or 4 to determine fault condition.

      If your Nordyne Air Handler isn't operating, make sure the unit is getting power by checking if the electric is turned on and the air handler disconnect is closed. Inspect the circuit breaker to see if it has tripped, or if the control board fuse has burned open. Confirm that the blower compartment door(s) are securely in place and that any manual reset switches are not open. A dirty or plugged filter can also cause issues, so check the filter. Finally, ensure the thermostat is operating properly and that the LED on both control boards is constantly ON.
