    Old Walk-in Compressor Starter

    I am trying to repair an old walk-in refrigeration unit made by Cavalier. It has an Aspera compressor with the following numbers:

    A5170A 145BG20

    I'm trying to replace the starter relay (current activated, no capacitor). I know that it was made by GE, but that's all of the information that is available on the outside of the unit. It is the type that plugs on two of the three motor winding pins that exit the compressor.

    Johnstone Supply sell replacements that look similar in the catalog, but I'm not sure of the exact one. Does anyone have some old books on Aspera that could provide me with some information? I they now part of Embraco and I've sent them an email, but they have not responded.

    Thanks for any help that you can provide.

    BrewBoy,

    The compressor you have is a 1/4 hp R12 unit. This must be a small walk in cooler. I have the old specs at work and will check it out for you Monday.

    There is a Supco solid start relay/overload push on relay that should work fine. The part number is PRO41, Johnstone number B11-924.

    powell

    Thanks, Powell.

    It is a small walk-in (5X7X7) that is only kept at 50F and is currently working great, even in a typical Texas summer. I had to repair the starter and while it may work for many months, I think it should be replaced. Any additional information would be greatly appreciated.

    BrewBoy,

    I could not find a parts list for this compressor. It is pretty old. I would try the solid state relay.

    Okay, I'll give that a shot. I've Googled every way I can think of and I come up with nothing on that compressor. Must be fairly old, however it's runs well and is fairly efficient. The starter is actually working, but I know it's on its last leg.

    Thanks again.
