I have a 2005 Mandalay with a Dometic refer, model NDR1292. During colder temps outside my refer turns off. Once the outside temps gets back into the higher 50s or 60 d range, the refer turns on. I don't believe it's an electrical issue. Any help/suggestions? Yhanks

Have you tried turning 'Low Ambient Switch' ON when outside temps drop below 50*F?You have 2 switches under top panel (open door and look up)One is a 'Climate Control Switch'----used during high summer temps/humidity. It energizes a 12V DC heater strip to help keep condensate from occurring (it pulls 12V DC continuously) The other is 'Low Ambient Switch'----used when outside temps drop below 50*F.It keeps the interior light on when door is closed.

Clarify. Is the refer eyebrow control panel turning OFF (no indicator lights) or the refer just does NOT cool? Doug

When it goes out all lights on panel go out. When the on/off button ispushed the lights come for a second and then go out until the outsidetemp gets above 60, about. The refer goes out usually when the outside temp dips below 50. Thanks for the responses.
