I just got back home in my 2001 Diplomat 38A. I plugged into my 30 amp service as usual. It showed I was plugged into 50 amp service. I played with the circuit breakers. Still said 50 amp service. I tried the front AC, it didn't work either. Strange. I was just using it.
I pulled out the circuit breaker and this is what I found.
The breaker was blown out on the rear side. Since it was on the power side of the breaker the breaker never tripped. I pulled the rest out and saw 4 more beginning to split in the rear. The main 50. Amp breaker was starting to melt on one side. I've never seen this before on the power side of the breaker. I replaced all the breakers with new ones. Now I read 30 amp service and my AC now works.
I will be checking these breakers on a regular basis.
Any ideas why this would happen on the power side of the breaker.
