To test the compressor relay pull the relay

straight off the compressor without twisting it. If

the relay has an external wire coil, hold the relay

so that the word top is up. Set the multimeter at

RX1 and place the probes on the terminals S and M.

the multimeter needle should not move. Next remove

the probe from M and place it on the side terminal

marked L. once again, the needle should not move.

Finally, remove the

probe from S and place it on M. the needle should

sweep across the scale, showing full continuity.

Now turn the relay upside down and perform the same

tests. You should get the opposite results:

continuity between terminals S and M and between S

and L; no continuity between M and L. if the relay

fails any of these tests, replace it: push the new relay onto the compressor terminals

and replace the terminal cover. If the relay passes these tests, test the overload

protector.

To remove the overload protector use a screwdriver to gently pry open the circular

spring clip that secures the overload protector to the compressor and snap out the

protector. Pull the two wire connectors off their terminals.

To test set a multimeter at RX1 and touch a probe

to each overload protector terminal. The

multimeter needle should sweep across the scale,

showing full continuity. If the overload protector

passes this test, test the compressor. If not

replace the overload protector. Reattach the push-

on connectors to the new overload protector, clip

it in place on the compressor and replace the

terminal cover.
