My outside unit works and the lines were frozen over this morning, however the air handler won't blow any air out.. all it does it make a humming noise
I have a Janitrol t-stat model HPT18-60... can anyone help with this? Is there someway to bypass the circuit board in the air handler to get air to blow?
Thanks!

Your blower motor for the inside unit is probably bad. You might just change the capacitor for the motor but usually when they just sit there and hum the motor is bad. If you know how to change the motor OK but if you do not you will have to call for ON SITE service and have them repair it for you.
