Pungoboy64 Report post Posted June 27, 2017 My rear air conditioner on my 2002 Holiday Rambler Ambassador seems to keep going on and off too often. When it comes on I hear the fan start and then the compressor will kick in. It is blowing cold air but will cut off after about 2 or 3 minutes and then will start again after 3-4 min. What could cause this to happen? Share this post Link to post Share on other sites
wolfe10 Report post Posted June 27, 2017 Is it ducted? Are forward vents open, bedroom vents closed-- that should help if you have ducted air. Bedrooms are very small. Depending on where the temperature sensor is, it can cause short cycling. Be sure the vents are not aimed at the sensor. Share this post Link to post Share on other sites
elkhartjim Report post Posted June 27, 2017 I assume you have a dual zone thermostat. The thermostat could possibly be failing for the zone controlling the bedroom. Share this post Link to post Share on other sites
hermanmullins Report post Posted June 28, 2017 Jim, Correct on the dual zones. Could one be set on one temp and one set on another. Even though you have two zones they are still both ob the same compressor. Pungoboy check both zones and set them on the same temp or turn one off and see if that makes a difference.

Pungoboy64 Report post Posted July 17, 2017 Thanks to all, I do have 2 separate units with 2 thermostats that are both ducted, I did have a vent aimed toward the bedroom thermostat so I redirected it and that made a big difference. Share this post Link to post Share on other sites
