[Sundance]

Rear unit not working, when 2nd comp. try's to start, it spikes Amp on L2 to 40 !
Didn't pop breaker because we turned it off ....
Jimmy is neighbor (Wow!! another great Guru and super guy) suggested to just try one compressor...we did and it worked for about 30 min at 10-12 amps and was cooling...then Amps spiked to about 30 on it and we turned it off...seems to be freezing up....
So no AC but cooler weather and rain forecasted...
Looking at rear unit per Ron's suggestion Jimmy and I pulled wall out from behind tool box and gained access to side and then pulled side panel off unit...didn't see control board but could see crimped freon pipes that taps could be added to...

Looking at front unit coils with light from nose of coach, they have lots of road gunk...
What have you others done to clean these, and how often?

Knowing these are 18yrs old...Jimmy and I think pulling rear unit, getting it rebuilt and re- installing is best option for now...thoughts?

Thanks
