Turned on the A/C's in our 97 U295 with the Dometic Duo Therm A/C units, and the rear A/C will turn on for a sec or two and then shut down. Does this over and over. Front A/C is running fine. I turned the thermostat down and it does the same thing. Any ideas?
Run capacitor or low pressure cutoff would be suspect.
I agree.
Over the past few years I have had to replace the capacitors in both of my AC's. When replacing the capacitors, I replace both the run and start capacitors at the same time. It is not a big job.

It started working again. But, I'm wondering if I should have a couple of extra capacitors handy, just in case this happens while traveling.
That eliminated the low pressure possibility.
