UPDATE UPDATE

Newly purchased used pop up. AC runs great for about 5 minutes then the breaker flips. 122 volts coming in. Standard OEM cord. Nothing else running. Original AC unit on a 2002. AC cools great for 5 minutes. One split breaker, 15 amp to AC and 20 amp to the rest. 20 amp receptacle service. Breaker feels warm. Bad breaker???? What an I missing? Thanks

The spare 25' cord that was attached to the camper cord was bad at the connection. YEAA. $30 fix. Thanks for the replies.

odd to have 122 volts and a bad connection.

About 4years old, buddy's breaker acting up and needs replacement.

OP found his problem. Loose connection in cord.

Sounds like low on Freon. That will cause too much cooling, and then freeze up.

A 2002 AC unit, 16 years old, isn’t working or working well, and your question is? Enjoy the five minutes! Or replace the AC.

Maybe just a loose wire connection at the breaker. Check the screw!
Otherwise since it gets warm, replace it. they wear out.
