    Ice o matic not making, compressor very cold

    We have a 1985 ice o matic that the R12 compressor went bad. It was replaced with a 134a compressor. It won't make ice and the compressor is very cold when we turn it on. Where do I start diagnosing this thing? I know this is a basic question and I'm a newbie and guess I'll have to take my hits, and I'm willing to deal with all that in order to learn. So thanks in advance for not giving me too much hell. 😁

    R-134A is not a replacement for R-12 in low temp.

    BTW
    Who replaces a compressor in a 35 year old unit?

    I know enough to know, I don't know enough
    Why is it that those who complain the most contribute the least?

    Sorry, I wasn't clear. We have a customer who has a ice o matic blah blah blah. We didn't replace a 35 year old R12 Compressor with 134a, the customer did. Thanks for the information.

    In that case explain the unit was destroyed by not knowing what they were doing!

    Why would you ever modify an IM?! Only thing worse than 134 in a LT app is a 134 condensing unit installed outside.

    They require a LBP compressor. We also don't know how much capacity was lost with his 134a compressor.
