Need to check the breaker to the unit at the electrical breaker box. You should have a dual 60 amp breaker that runs the unit. Also if you removed the front of the furnance on the inside the system will not work unless the front of the furnance is on. There is a safety switch that will not allow the system to run with the door off. There could be the problem if the breaker is on and electricity is supplied to the unit that switch may be out and need replacing. The furnance is operated on 110 volts the condensor (outside section) operates on 240v you need to insure that the proper voltage is supplied to both.
Since both units work together yet operate seperately if the furnance comes on and the condensor doesn't then there is an electrical problem at the condensor (more than likely the contactor switch) if the condensor comes on and not the furnance then there to is an electrical problem (either 110 volts not supplied) or the switch to the safety cut off is bad. Now if neither furnance nor condensor comes on there could be improper power to both or a bad thermostat since the thermostat activates both furnance and condensor. Good Luck on repairs

Hello Sheri Turn the thermostat off BUT the fan switch ON/AUTO to the ON setting this will speed defrost time give it 3 hours.Replace the air filter.Was it clogged?Is any thing at all blocking the intake grille?Poor air flow is a cause of ice.Turn it back on and see if it freezes up again.If so, have the freon level checked it might need a recharge.If not a bad/neglected filter will do it every time.

Air conditioner not working

the outside condesor unit is not coming on for a number of possible reasons. First check your breakers for a tripped breaker, even if they appear on, turn the ac breakers off and then turn them back on. if after this, turn on the thermostat, outside you should here the contact switch on the condensor unit humming. if still no power, check for any breaks on your wires going in from the house, still nothing give a call back

Fan setting only works

Air Conditioners have a fan speed relay built in the unit, faster for cold air and slower for warm heated air. It is very possible that your relay is defective
