Mariner Posted December 31, 2015 Report Share Posted December 31, 2015 Just had a new rear rooftop Dometic heat pump installed. It seems to be cycling on and off on the A.C setting too fast. The fan comes on, then the compressor kicks in as it should, but will shut off again in less than 10-15sec. After the usual 2 min. wait it will kick back on, and then run for a short while before it again kicks off. This can't be normal, our old one never did that. Is there a setting somewhere that sets the temperature range for starting and stopping? Link to comment Share on other sites More sharing options...
