Goodman Customer...

"A Goodman customer walks into a bar...." I can think of the possibilities. But every system has it's price point.

:)

BTW: Ed can buy one and get's to keep it when he is done. If not borrow one.... Ed- See Marty at Interstate in Brighton.

    Ed,

    Try installing a time delay relay in condenser wiring compartment on 24v signal . If they have a non-digital tstat it could be tripping because of people fooling w/ the it, not giving it time to equalize pressure before next start-up.

    Whats the amp draw?? I bet you'll be needing a capacitor soon.30/5 370 volt I believe.

    Good luck, Tom

    A few things come to mind

    Locked rotor on compressor, short circuit (squirrel chewing a wire does wonders for your remaining hair), water in system such as a conduit pigtail, breaker may have arced a few times and need to be replaced.

    I would get a data logger with amperage reading, see what trip point is. May be a voltage drop in the system or elsewhere which increases the amperage above limit.

    I imagine this is a 220V setup?

    A what?

    A data logger did you say? Good luck with trying to charge a goodman customer for that.

    I'm sorry just clowning alittle bit..please forgive me.

    I'm with you guys..capacitor,loose wires and, maybe a burnt breaker at the panel box.Plese remove breaker and check for burnt marks on the back of it.

    And one more thing if she has a fan delay relay on her please replace that as well because, it just a matter of time and you will get a call for a frozen up unit.

    Circuit Breakers

    Evening Ed!Low volt connection inside wire nut broken causing chattering or ,is the C.B.panel located in a hot area,like a garage? Or one of the other ideas allready stated! Let us all know what you find out after you fix the problem.Enjoy!

    Could be ANYTHING...

    We need some measurements and a basic explanation where you think it is coming from. What is the FLA when everything is running? Pressures and temps would also help. Breakers DO FAIL, but I will not jump to conclusions here. Have you checked you run CAP?////mfd rating? How do the contacts on the contactor look? What kind of stat, with TDL or not? Why even tackle this if there is no INFO...? It's like saying I have no A/C,..What is the problem.....

    type

    One more thing, is the breaker a HCAR type? The nameplate on the cond. unit usually requires a HCAR rated breaker.

    No A/C

    If all other things look good, I'd check the line voltage connections at the unit and in the panel. Also, if the customer is on the end of a street where there has been a lot of developement(no permits pulled on electrical equipment)you could be suffering a voltage drop at peak usage times. Breakers are cheaper than data loggers:)

    Yeah, but

    the damage caused by oversizing a breaker for a suspected voltage drop condition might have if it exceed the protective threshold of the equipment... (in case you were anticipating up-sizing the breaker and not that you were)....

    Data Loggers Rule :)

    Your point about development and voltage drop is excellent by the way.

    Thanks Mike...

    The list of possible causes for a tripped circuit breaker is ENDLESS.

    Hope you find the end very soon.

    Best of luck.
