You turn power off to the unit at the breaker. Unscrew the one or two screws that hold it on with a philips screwdriver. Cut both wires on the old one close to the box of the bad part. You need to splice the 2 sets of wires together, normally using porcelain wire nuts to insulate the raw wire or if it comes with shrink tube, install the tub on one wire before you twist the raw wires together, then slide the tube over your splice and heat it with a lighter evenly until the tubing shrinks covering the raw wire.

Emerson model#CR519B. The unit just stopped working. If plugged in a motor runs for about 8 seconds and clicks off; about a minute later it repeats. Help

I had the same problem with a small wine cooler. It happened to me twice in 6 years. Both times I had to replace the starter relay.

I couldn't find any repair facilities willing to work on these small wine coolers or refrigerators, probably because the bill would be more than the used fridge is worth. If you feel confident around a volt/ohm meter and electricity, you could learn how to test this and maybe fix it yourself.

You shouldn't do any of this if you aren't familiar with using a Volt/Ohm meter and can safely and confidently work around electricity.:

  1. Unplug the fridge
  2. I first tested the compressor with an Ohm Meter (see how with youtube video below or by reading how at It was good, but it kept starting and stopping within a few seconds.
  3. Basically my starter capacitor/relay wasn't working. It supplies temporary starting voltage to the starter relay in the compressor, then cuts off to allow the motor to run.
  4. I bought a Supco 3-in-1 on Amazon for less than $13 and hooked it up according to the supplied instructions. It lasted about 3 years.
Of course, the factory recommended repair is to buy the original replacement relay, but it will be more costly and harder to find.

I bought a Supco 3 in 1 Hard Start relay sized for the HP on my compressor. Mine was the Supco RCO810 (see link below).

NOTE: Before I replaced the starter relay and overload protection with a Supco 3 in 1, I learned how to test the compressor with a Volt/Ohm meter. If you don't have a meter, you can buy them online or inexpensive to free with a coupon at Harbor Freight.

Installed 3n1 start kit - did not help. compressor shows good resistant between all windings, not grounded, but hard start kit did not start it either. But this video might help You to wire 3n1.

Removing compressor from skybox

Maytag never offered a replacement compressor for the SkyBox units. It was not a cost effective repar to make. If you are sure the thermostat is supplying 120VAC to the compressor, you can install a Supco URCO410 relay/capacitor/overload kit. This part should only be installed by a qualified service technician.
