Hello I have a Goodman CKT42-1B compressor is currently running on and off with air-condition on. Any one have a wire diagram for it? Thanks KX

Is condenser running? Verify amps to be sure both fan and compressor are operating. Should have 2 wires to compressor and 1 to fan on top of contactor. Then on the capactor (herm) terminal is the remaining compressor wire. On fan and c would be the 2 remaining wires for the outdoor fan motor. Then 1 more wire on c that jumps to the top of the contactor on the other side to which the first fan wire connects. GOOD LUCK.

The compressor has three terminals, Common, Start and Run.... The terminals read left to right, top to bottom just like pages in a book. So if theres one on top, its Common then Start will be the first one in the next row. If theres two on top, it'll be Common on the left and Start on the right then Run on the bottom.

The run capacitor wires in between Start and Run and line voltage is applied to Common and Run.

Please check gaz pump in the compressor unit...you´ll find it very hot and most of techs tell you to change it for a new one...don´t...get an tech able to refill pump oil in the compressor unit""
It will go to renewed condition almost for free

Hello...
Apparently, there is an overload or shorted wires. Elequipo Disconnect electricity and check the cables are in good condition.

Get rid of the hard start cap. Hard start capacitors should never be used in conjuction with normal compressor operation. Contact your local dealer for goodman and find the correct dual capactor for your machine and install it. Odds are your dual capacitor is either not functioning properly due to over voltage strike or it is the wrong size. On the wiring to your compressor, black is normally common and lead directly back to your main contactor. The red wire is the running lead and again normally goes to the c connection on the dual capacitor which leads back to the other side of the main contactor. The remaining wire on your compressor goes back to the herm connection on your dual capacitor. You may have swapped the wires for your power supply to your capacitor. I did this once and I figured it out about 5 hours later after I performed a wire by wire check against the wiring diagram. If you switch the wire around you turn the start windings into run windings and vice versa. They are not designed to be interchangeble. Just check your wiring against the diagram and the problem should clear up.
Hope this helps.

Hello, you can Ohm the compressor windings with a multimeter. Just kill power the the unit, remove the wires from compressor and check each winding. You should have resistance, if not the windings are open and compressor must be replaced.

Possible Solutions:
You have no voltage going to the unit. You did not say if the compressor was running.
If no voltage then check the breakers. If breakers are tripped could be a bad motor or a shorted to ground compressor.
If the compressor is running possible solution could be a bad run capacitor.
Check for any lose wiring (MAKE SURE THE POWER IS OFF). Many problems occur because of dry contacts. Simply by tightening any wires and wire nuts and removing and reinstalling any spade connectors.

Hello Check the AMP draw on a running compressor.It should match the value on the compressor tag.It is overdrawing.maybe overcharged system (freon) can cause wire burn.High head pressures will cause it too.

yes, but I would try a "hard-start" kit before replacing the compressor itself

Several problems could be the cause of the air not cooling. 1 the capacitor for the compressor is out. 2 the compressor itself is bad 3 the unit could be low on freon 4 the thermostat isn't wired correctly. All of these problems would need an a/c tech to look at due to the complexity of the system. Good luck hope this helped you somewhat
