I think the compressor is short cycling

[globalcompressors]

Klixon overload.

It drops the common side power input
on the compressor itself. When the unit cycles too often and is still under a load, often the overload protector will drop the power until
the pressures equalize and the compressor is able to start. It's only good for a few times then will begin to burn or crack the disk.
When this happens, the compressor will either stay open and not start or will burn up if the protector is welded closed.

Yes, you do need an equal replacement. Different size compressors have different amp loads and require different overloads.

Go with a 3 in 1 start kit. It will work.... for a while.

Usually by the time the overload is shot or the relay has burned up or some other problem occures in a 30 + year old compressor, this is usually the only other, cheap option.

klixon  duh not clicks-on. I am an idiot sorry

mine made contact with metal and burnt a hole in it. I assume its not ok to use this klixon anymore

No you're not... and if you don't ask...how will you learn?

If you are not in the "business", how would you know what it's called? The overload does "click" when it's called for.

Good call on the burned spot. I wouldn't use it either. Like I said above, get a replacement or use a "3 in 1" start kit for that size
compressor, probably a 1/4 hp.

Good luck!    '>

I am going to order one from sodajerk.  I think I have a wiring problem with the uss-8-64 and not a bad T- Stat.   Steve at sodajerk told me to disconnect one wire from the T-stat to test it and the compressor still didnt shut off.

Also what setting should I run the T-stat at? Some one told me to run it on 3
