Hello Joyride and . We look forward to reading of your adventures and experience. I am sure you will enjoy the website and forums. Good luck and keep us posted.
Is your coach a 30 amp or 50 amp? If 30, the rear air cond. may only come on with the generator running or may have a switch that selects front or rear unit. Please give us the make and model of coach.

Thanks for the reply it's a 50 amp, I turned the front ac off to check if it was that but no response from the unit, the coach is a 2004 National Tropi-cal

I am sure you have checked the circuit breakers. Do you have 120 vac at the roof unit junction box? Have you checked connections at both ends. I have seen an electrical circuit push a volt meter but break down under a load. Will you be able to troubleshoot a control board with some direction?

On mine the rear unit wouldn't work. Took the cover off (inside the RV) and reached in to try to spin the fan, it was frozen. Gave it a firm twist and that freed it up. Worked perfectly after that. I'm assuming the problem with mine was that it had just sat for too long. I of course did this with the power to the unit off. Just a thought.
