NO! that unit will NEVER reach 30*f cold.The refergerant used does not run(operate) that cold.

Replace the compressor starting capacitor. This might be the problem. If not then the compressor need to be replaced.

Hi,
The capacitor for the fan motor is bad...change that first and then do the motor if that don't help...

thats like saying yep and nothing else whats your question if you say its bad replace it please clarify

Hello The new motor sounds HOT wired.It must have one leg connected to the blower relay.If it is off the relay(correctly) ,the relay is stuck/welded and should be replaced.In the blower unit.

you will need to clean the coils, with a water hose. make sure you have the power off. This will de-ice the unit. as it is either diry coils or low freon

Is the fan in the outdoor unit coming on? If it is, that narrows the problem to just the compressor or capacitor. If neither is running, check the disconnect or circuit breaker or fuses that are located close to the outside unit. If the unit has power, remove the cover where the power goes into the outside unit, set the thermostat to make the unit come on and see if the contactor is pulled in. If it is, use a meter to check for power on the load side of the contactor. If the fan is running, check the capacitor for the compressor. Most units use one that works both the fan and the compressor. If the capacitor looks swollen then it is bad, otherwise use a multimeter with the capacitor check function to test it. If the capacitor is good, check the compressor motor windings with the multimeter on the resistance function. Let me know what you find and I can give you more advice if this doesn't get you going.

Hi,
The one side of the contacotr in the condenser electrical box is welded closed...

Check inside and outside coils for cleaning with coil cleaner spray

Check capacitor(remove and take to appliance parts dealer. They will checkit)(easy job)

Hello I would add a HARD START KIT to the run capasitor (if there is not one already).This makes the compressor come on easy.If the breaker trips during running time the pressures are too high,hose off the condenser coil (fins).The unit might be slightly overcharged but I would be careful before adjusting the freon at all.

Most likey cooling fins are plugged and also my need new compressor or low on refrigerant or refrigerant oil. Could also have plugged intake filters in the intake.

Check the outdoor unit to see if it is discharging hot air out of the top ofd the unit, check the insulated suction line to make sure it is cold or sweating. Try to listen to the outdoor fan and the compressor to make sure they are both operating

Turn the power off and then back on, canyou here the copressor come on?
