AC overheats flips breaker on AC unit (3807)

Postby justtls » November 21st, 2015, 1:47 pm

Greetings all and thanks for taking the time to read this. I finally got all three of the AC units to run correctly. Unfortunately the unit in the back stateroom runs for about 15 to 20 minutes before it overheats and flips the breaker on the AC pump itself. All 3 AC units get water from a central water pump and discharge through separate areas so I dont think its the intake, could it be low on freon? Can that cause a unit to overheat. Thanks again for your help.

Regards,
TLS

How is the flow from its water discharge? May have a semi-clogged heat exchanger? I know somebody sells something you can flush the lines with, but the name escapes me.
Thanks

Are you sure the the breaker tripping is the result of something on the unit overheating? What is exactly is overheating?

I had a similar issue on my 93 Silverton. AC would run for 30 min and then breaker would shut off. After much investigation it turned out that the breaker was weak. I replaced the breaker with the identical new one and it is still running strong with the new owners.
