The unit will run and the compressor will come on when i push in the button on the outdoor power supply on the unit. How can i solve this problem ?

    something has it locked out

    check 24 vac from transformer be sure you have it

    check primary side of trans. should have 240vac there

    jump red green and yellow at thermostat

    remove the wire before you do this or you could fry the cooling anticipator

    jump red and green you should get indoor fan add the yellow and you should get compressor too,?

10 year old Goodman central AC won't come on after mini power outage. Breakers and wall thermostat OK.


Check the start capacitor for proper value and replace if necessary.
Ditto for thermostat. There are also some fuses in the air handler that might need replacement.

You may have had a power surge that had a bad effect on electronics of unit. Make sure that unit is receiving power for one thing. U might try to reset the electronics by completely shutting off all the breakers to compressor and air handler and waiting a few minutes and then reconnecting.

Generally, the fuses are located in a box outside by the outdoor unit. The box has a door on it and you will probably have to pull a cartridge out and the fuses will be behind the cartridge. If you don't have an ohm meter to check the fuses , just go to home depot, lowes or another hardware store where they can check them for you. Be sure to check the circuit breakers too.

1 posible cause.the thermostat supplies 24 volts to the outside unit to control the contactor if you hear a ligth huming on the outside unit this is the being activated. if this is the case then
check to see if any ants are in or around the unit see video, they will usually climb to dry areas before during or after a storm and for some reason they like the contactor if this is the case cut all power to the unit and clean contactor spray the area around the unit with an insecticide ( not the contactor) replace cover and test unit.

Central AC comes on but won't stay on. Could it be low on coolant?


this is possible only if there is a Low Pressure Switch on the unit. Most residential units do not have those but it is possible. I'd look else where, such as thermostat for starters.

Hello BWOOD Check the thermostat FAN button is in AUTO position not ON position.That might be it .The relay is in the blower unit but they RARELY become frozen/welded stuck on.

Furnace runs on heat, air conditioner does not


If you have a Gas furnace in the Attic then the answer is yes. The outside condenser will not run if in fact you have a gas furnace.

My goodman cple18-1c model central AC unit blowing hot air


Ths sounds like the outside unit or compressor is not kicking in, check for power to the unit at the breaker box, or at the bottom of the contacts!

Goodman Furnace/AC unit not working 3a fuse blows even after replacement. once thermostat is turned on and clicks to start ac unit the fuse blows


3 amp is standard.the fuse is blowing to protect the transformer.It is telling you that there is a short in the low voltage wiring.Goodman also had an issue with the coil shorting on the contactor.To prevent damage.....i'd call a pro.It should be a fairly simple repair.

Goodman CK60-1C model central AC unit blwing hot air


Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.
