Rooftop A/C won’t turn off

My roof top A/c won’t turn off eve when reaching temperature. It will turn off by the thermostat with on/off, but will not turn off even if I set it to 90 degrees

See if you can set it to "auto", might be set on low or high speed.

Set thermostat to fan and select auto. Then try the AC and see if the fan shuts off.

You didn't mention the model or type of A/C.

For what it's worth, if you have the Atwood AirCommand A/C, when set on auto and A/C mode, the fan will continually run on low when the compressor shuts off. That's how it is designed. It has two fans and the one that runs when the compressor is off uses very little power on low. There have been several threads on this topic both here and on IRV2. Not sure of your model or type but maybe this helps.

If it is a dometic mine occasionally “looses its mind” and will not stop. Kill all 12 v and a/c power to it and the thermostat. Needs a hard reboot. It’s happened maybe 3 times in 2 years. I just shut off the main breaker and flip the whole coach power disconnect.
