Model # ckl49-il serial # 0506126514. This unit stopped working yesterday, noticed the fan on the outside compressor wan't turning, how do i test the capacitor and fan to see which one to replace?
By far the most common problem with air conditions is the relay (known as a "contactor") by the air conditioner industry. This allows a low voltage (24 volts) electromagnet to turn on the 220 volt motor for fan and compressor. A replacement will generally cost about 50 to 75 dollars on Amazon.com.
Look for the wires entering the unit, The pair of wires entering the unit will go into a small (4" x 2" x 2") unit (the contactor). Another pair small diameter wires will go into the contactor (those are from the thermostat (or control panel of your furnace blower) and control the electromagnet switch.
The pair of output wires exit the unit and go to the compressor motor and fan.
You can check the output power by
1) Turning off the circuit breaker to the A/C
2) Unplugging the switch (must be a second switch within 3 feet of the A/C) near the house
3) opening up the outside panel on the A/C
4) Set voltage meter probes on the two output wires on the Contactor (make sure voltage meter is set to 220 volt AC range or higher)
5) turn on the outdoor switch
6) turn on the circuit breaker (if no body is near the unit and you can see the voltage meter without touching it)
7 check voltage meter to see that is says 220 volts AC
If not, then the contactor is bad and needs to be replaced.
A professional can usually do it for $200 including service call. I highly recommend calling a professional if you feel uncomfortable in any way about working with 220 volt systems. This voltage will kill you if you make a mistake!
