Carrier out side unit not coming on. Removed the contactor waited 1/2 hour reinserted and only heard a click. Any idea's? Still blowing cool not cold air. thanks!

I have found that turning off all power for a minimum of two hours will reset most errors,. When you switch the breaker back on, you will hear relays clicking as part of the self testing. Wait 15 minutes before operating the unit.

Well you need to set your defrost cycle on every 30min,that doesn't mean it comes on every 30 min,it just checks it,there's little black or white switches on the board and on the door it show you how to change them for your time,

Here is what to do . Pull out or turn off Electrical disconnect behind unit . Carefully remove panel covering controls in unit . Note most units have a flat panel with a few screws, but some GE units have a welded metal box on top of unit which needs to be removed. After exposing controls. replace or turn on disconnect. Then take a plastic handled screwdriver and push in on center of contactor (boxlike part with a lot of wires hooked ) If the compressor now comes on release contactor , and check for 24 Volts AC at base of contactor where thermostat (small wires that run on outside of black refrigerant line ) with thermostat on and calling for cool you should measure 24 to 28 volts . If voltage is present replace contactor after disconnecting from power. If no voltage go inside , remove cover from thermostat, and check for 24 volts between red ( R) and yellow (Y ) terminals on thermostat , If voltage is present , replace thermostat , no voltage check voltage in heater / air handler if you have voltage at air handler , replace thermostat wire from heater to thermostat / if no voltage check for blown fuse in heater , this should be either an inline fuse or an automotive type fuse plugged into circuit board (with power to heater disconnected check broken wire or black mark in fuse when held up to light. If fuse good turn on power to heater and check for 230v to one side of transformer, if you get voltage to Primary (incoming side ) of transformer, check output side of transformer for 24 - 28 volts. If transformer shows input but no output replace transformer after turning power off. If you heard a buzzing or grinding noise , when pushing in contactor , but compressor didn't start look at run capacitor (this is round or oval shaped object with wires going to contactor and compressor ) Looking at area where wires plug this should be a flat surface , if it looks domed shaped or bulging out , it is blown and needs replaced , use same mfd rating and 440 Volts to be on safe side. / If there was no noise from compressor when contactor was pushed in , put your hand on top of compressor (black object in center of unit ) If hot , allow to cool for at least three hours with power to unit turned off and retest . If compressor comes on after cooling , check for bad fan motor in outside unit (it may make a squealing or wining noise and stop runing for a while , also check for / clean outdoor coils
Hope this helps .
Thanks,

Hi,
If it is just the fan then the motor needs to be replaced...let it cool a few hours and then try it and see if it is just the fan or the fan and compressor that does not work...
If neither will start then either the t-stat is not working right or the contactor in the outdoor unit has gone bad...

Start by making sure its getting the right voltage (line and load side of the contactor) then check the capacitor/s. Let me know what you find so I can go further if I need to.

your indoor unit is only circulating the air in the house. for your condensing unit. check your breaker in the electric panel. your contactor or your capacitor.

The board is bad, what you can do is splice into the common (blue) and Yellow t-stat wires and connect them directly into the contactor and hopefully the reversing valve engages, giving you cooling for the time being

I have a Rheem heat pump/airconditioner, Mod # RPFA-036JAS, that I have had problems with for at least 5 years and have paid over $1,000 in parts and service calls. I can vever recreate the problem when a tech is here. It usually happens in the middle of the night. I hear a Click, ckick, click sound, through the unit and it sounds like it is comming out of my air handler, but the outside unit also clicks at the contactor and the condensor cooling fan moter will start and stop about every half secongd or second. Both contactors have been replaced, the small one twice, one capaciter
has been replaced. I allow the unit too cool down and its alright for a few hours. That is difficult when the outside temp is below zero. HELP PLEASE!

If the T-stat is on cooling take a volt meter and touch one lead to each side of the low voltage termanals on the contactor and if you have 24 volts the contactor is bad, if not start back tracking
