You need to check the wiring to the limits and safety devices with are in a number of locations, make sure all connections are tight.The most common cause for the blower to run is the high limit device which is the one mounted above the burners on the flat metal panel with two wires.

Have a package unit that is tripping the circuit breaker early in the morning, around 5 a.m. each day for the past few days. The blower fan motor was recently replaced, but it seems to work fine, all day...


Excessive current draw when motor first starts could and most likely does cause this breaker trip. I would check wiring connections to motor, check cold motor start up amperage draw, also breaker may be the issue (weak bimetal spring).

No A/C.


It maybe the blower motor. Determine if the blower motor is getting ac, if not getting ac to the blower motor then there might be a breaker, which would probably be located somewere near the motor, or the motor has an internal breaker or fuse.

AC fan stopped


Sounds just like a seized bearing on the fan motor. They can be repaired but it's usually less to purchase a new motor. Now all you have to do is figure out how to get the motor out. To get you started, you need to partially disassemble the top portion of the condenser cabinet. This will give you access to the fan motor assembly. Which model do you have? That information will be on the nameplate which is on the side where the electrical enters the cabinet. That reminds me, always pull disconnect and trip breaker before starting.

New motor runs but doesn't blow air through the registers


Is the blower wheel turning? Did you by chance have to remove the motor from the blower wheel to work on it? If you did, did you put the blower wheel back on in the correct direction of air flow? Also, did you put the correct capacitor back on the unit so it can get up to the required rpm's? These are things that you will need to check for. If the motor is running and the blower wheel isn't and the wheel is tight on the shaft, then you will have to replace the motor. The brushes may be bad on the unit and it's not turning the shaft. Hope these ideas help.

Power to AC does not stay on


Sounds like you might have more than one issue. If the breaker is tripping could be the compressor. If you have to press in the contacts to make it come on something is not sending 24 volts to the contactor. may be a bad wire that runs from the outdoor unit to the control board in the furnace.
