Top 20 Goodman CKL42AR42 Air Conditioner Questions & Answers

possible a failed start/run capacitor call an electrician for a proper diagnosis

3 1/2 ton

the model you have in your question is a 3 & 1/2 ton condensor.

the name plate on side should give you that answer

150 is low for high side pressure. may have to add more r-22 to system. if you had a blockage high side pressure should be higher. have you turned both service valves at condensor ccw completely?

Their is a swicch on the door that you opened . Reinstall door, making sure switch closes. .

mine is also doing the same thing. only thing i can think of is maybe the valve in the compressor is stuck. but im no tech so dont hold me to that . email me please if you have found an answer to why it is that way. thanx Tim K. Email: [email protected]

bad capacitor or motor.

check to seif you have 240 and 24 volts available at unit. remember electricity kills. if you are not qualified to check it get a professional.

42,000 btu

not all electronic leak detectors pick up r410a-puron. Evaporator coils are notorious for leaking puron. your coil should be under warranty.

The compressor has to be replaced if the bearings are bad in the compressor. Replace the condenser fan motor if the fan motor bearings are bad.

65 psi on the big line in cooling is kinda close but this greatly depends on indoor and outdoor temps

118psig on low side & 350 psig on high side.

3 amp fuse blown in air handler, bad contactor in od unit, no 240 volt power to contactor.

typically it goes to yellow from tstat. it breaks circuit to od unit contactor.

Hello, try spinning the fan blade with a thin object such a a stick or long screwdriver, if this gets the motor running the capacitor must be replaced. If it does not get it going the motor is fualty and will have to be replaced.

Could be the run capacitor is bad. Usually they bulge at the top where the connections are, but sometimes they are bad but appear to be fine physically. You would need a multimeter that reads microfarads to see if yours if good.Below is a link to the part in question. Yours should be rated at 50/5 mfd, 370 or 440 volts.50/5 MFD 440 Volt Round Dual Run Capacitor

That depends upon the operating environment of the a/c system.The high side is directly related to the outside temperature and the low side depends upon the indoor temp, air flow across the evaporator coil, the relative indoor humidity and the static pressures of the duct system. There really is no rule of thumb to go by here but if all is operating properly then you should see something like this:

At 80° F the high should read from 277 psi to 295 psi with a clean condenser coil and the low will be about 116 psi to 130 psi or so if the blower and inside coil are functioning properly and the house temp is not too high or low.

*CAUTION*
If you are working with the high pressure of R410A refrigerant, also known by the trade name of Puron, then please take precautions to avoid accidental exposure of the face, eyes and exposed skin of the refrigerant and the POE oil it contains. Severe frostbite, lung damage and loss of eyesight may occur if exposure to raw refrigerant is experienced. Please consider calling a professional in your area to work on any refrigerant system.

Hello
There are a few things here that could be wrong.
1 Fan motor start capacitor is bad.Silver battery looking device on side of fan.Remove and replace with a new one.

2 Contactor for fan motor is pitted or burnt .If this is the case you will need a new contactor.

3 Fan motor is bad.Check top two before assuming this.
Check all fuses and circut breakers also.
