I was wondering if anybody knows how to check properly if the compressor is working or not. It appears that the compressor starts to kick in but shuts down, I dont know if it is an electrical problem or somerthing. any help would be appreciated.

thanks...

what do you mean when it starts in and shut down??? does it do it alot? if it comes in and out alot within a minute its fine

no.....it like kicks in and tries to start but then shuts down and doesnt come on again...

Probably low R134 level kicking out the safety switch. You need a gauge set to check the system.
