Air Conditioner Issue

[marbilupton]

My air conditioner is stopping running and then in a few seconds starting back up again. It is doing that 3 or 4 times in a row. Does anyone have an idea what might be causing this?

marbilupton, funny, we are having the same thing happen with both our a/c's. I posted in here too. I will keep an eye on your posts as well as my own to see if anyone comes up with a good reason. We did reset our thermostat by following this from another post.....Posted By: ac650 on 09/21/11 08:30am

I'm a retired Telecom and computer tech. Sounds like you may have a communication problem in the RJ-11 jacks. To test comm integrity, start with the on/off switch OFF on the comfort control unit. While holding both the Mode and Zone buttons down, turn the switch ON. The display should show "FF". Release the Mode and Zone buttons. If comm is OK the display will show both units in the off mode. If display shows "EE" there is probably an issue with the RJ-11 wires/jacks but you could have a bad board in one of the roof units. RJ-11 jacks are infamous for poor connections. Telecom guys HATE them!

...Had that happen several years ago as well on our TT. Turned out to be a faulty thermostat. Problem went away after replacing it.

'Twas a cheap and easy fix, not much lost if it doesn't fix it, so I'd start there.

Low voltage coming into the motorhome?

Had that situation on our front A/C. Turned out to be a faulty thermostat.
Had it replaced and no more trouble.

Describe more, but may be a thermostat.

If it a basement A/C that is normal. Has to shut down for a few seconds to start or stop the second compressor
