Question about Dometic Rooftop RV Air Conditioner
2007 Mandalay Presidio. Have two 13,500 roof units 620525. Just got back from a trip where we did not use roof air and experienced freezing temps a couple of times. Back in Florida I discovered the neither unit will cool. They will blow warm air for about a minute and shut off. Is there a freeze reset?
Yes and no .. Freezing temps should not affect your A/C at all ... BUT .. there is a freeze control box, its called a control unit to prevent itself from freezing up and burning out, take down the lower cover and you will see it. Your problem is more likely to be more central since neither are working Thermostat or even the control box's in genera, even could be a freon problem if the cold weather was really bad and you could have a leak on your lines, check it out and see what you got!
