Question about Dometic Rooftop RV Air Conditioner

1 Answer

My thermostat has to be set to 85 to get my trailer heat to 65 - when set to 90 I can reach 75. Could not find a contact to clean - wondering if there is something else I can try?

    Sounds like your t-stat is off. Is it the type you can rotate or is it a digital one?

Either replace the thermostat or if it is an old thermostat it has an antisipator setting if it is not digital it may have to be calibrated or it is to close to something that gives off heat so it is being tricked
