I have a Dometic Brisk II 13.5 air conditioner that is about a year and a half old. It runs great, however fairly regularly after it reaches the set temp on the thermostat it shuts down as normal, however it does not start up again as the temp in the trailer rises. If I shut the thermostat off for 10-15 seconds than reset it to the a/c it will start up and run fine. I have replaced the thermostat, but it does the same thing. Does anyone have any ideas?
