I have a Goodman CPE30-1AB (Outside heat exchanger), with a Goodman (air blower) as well. Air blows inside, but not cold. Outside unit is not turning on at all. Can you please assist?

sounds like chattering coming from the contactor replace it and your buzzing will go away.

If the power failure was due to a storm the blower motor may have shorted out. Check that the breaker for the inside unit has not tripped.

either you have refrigerant leak or compressor bad.

contactor bad or no a/c power to condensor.

best to call a certified serviceman to ckeck outputs ,times, and tempertures.

The inside fan will run while the unit is in defrost. The electric heat strips should kick on to help prevent you from feeling this cold air. When the unit is in defrost it is essentially running in the A/C mode. You should make sure the electric heat elements are working then go from there.

Sounds like compressor not running. may be a bad capacitor, could also be low on freon.

Does the cpompressor come on if not the sound you here maybe the contactor. Check float switch inside. It is underneath the unit or in front of the air handler. Drain stopped up need to blow out drain. Check outside breakers. possible bad capacitor on unit. Need service tech. Rusty

Your in house core could have frozen over. check the core inside the indoor blower unit. it may have frozen over. this will interrupt the cold air function.

blowing cold air on this furnace usualy caused by high limit trip, or flame roll out. the first one, (high limit) is from insf. air flow. (blocked filter,bad zone damper?
The second,(flame roll out) caused by bad heat exchanger,blocked vent.ect.
