Bedroom A/C not working.

[MikeJ]

I have a 2019 jayco talon and the bedroom ac stoped working when running with the generator. The man living area ac worked just fine. Also tried running the bedroom ac when connected to shore power and it worked fine. Checked all the breakers on the gen and in the breaker box, and they seem to be ok. Also noticed when running the generator that the microwave does not have power. Any help would be would be great.

Bad connection or bad contactor in the transfer switch is a possibility.

I am assuming this is 50 amp service. This connection feeds 120 volts in to your rig through 2 different lines. If you lose one line the other will still power half your rig. It is normal to have one AC on each leg.

Since it works on shore power you have narrowed it down quite a bit. Like Grumpy mentioned, I would start with the transfer switch. Tighten all connections with no power applied. You can measure the voltage coming from the generator at the transfer switch. If you measure it coming in but not going out, the switch may have a bad contact.

If you don't measure it coming in, the next check would be at the generator. Loose connection, bad or partially tripped breaker, or perish the thought a failed generator.

Voltage tests will tell you where the problem is.
