Title: compressor just clicking and not coming on
Post by: VMC 81 on January 18, 2010, 03:32:41 pm
I have an 81 and when it is powered on I hear a click click sound and the compressor does not kick on. It was working but now this is all that happens. Any ideas?

Your compressor is drawing too much current for some reason & the over-current "Klicit" (an over-current & over temperature circuit-breaker built into the start-run relay area of were the electrical lines enter the compressor on its side. ) is cutting out to prevent it from over heating.

Why?
A)the compressor is starting to seize up.
B) the compressor is over heating due to a defective cooling fan or blocked air-flow through the condenser coils ( dust bunny's plugging the fins) OR it may be over heating because of a low charge of freon due to a leak ( a compressor uses the freon to transfer it's motors heat into the air-flow by dumping it (the heat) into the high pressure gas going to the condenser coils this way as well as the metal case of the compressor itself).

C) a defective overtemp/current "Klicit" or start-run relay itself. or a loose electrical connection(s) on the relay itself.

D) it just doesn't like you.  :tounge:

The attached picture is from a Vendo V-110 but you'll see that it has all the basic components to help you identify them on your compressor.

Thanks for the information, I will check the connections and clean them up and try it. It was working one day and literally stoped the next.

More likely it's the start-run relay is bad.
