There is a FREEZE SENSOR probe that sticks into the bottom of the blades usually blue and white attached to a white 20 gauge wire. You can reach it from the inside by taking off the ceiling pack and looking up into the blades / coils you’ll see em all u gotta do is look up. It falls out every now and then.
What was the outside temperature while you were running it?
Lack of airflow. The cold from the coils has to be transfered to the air. Wrong air filter? too restrictive? Cool > coils > air > RV. Heat flow in reverse so the coils are getting too cold means not enough warm air over them.
More than likely, air is leaking from the output side of your ac to the intake. Take the bottom shroud off, then use aluminum ducting tape to seal the edges of the foam divider that divides the two sides. Also, check that your thermistor probe is inserted into the radiator because it should be shutting off your compressor before it gets this bad.
To avoid this with mine. I leave the fan always in high and only mess with the temp setting. Ps. Cats are fine with 75 degrees imho
Had a similar issue in an otherwise working unit. Switched the fan to low/high instead of auto and haven’t had a problem since.
Could be a bunch of factors.
Is it a bigger unit for what ventilation you have.
Is it getting airflow
Has it been running nonstop with windows or doors open?
Source: New ac, worked for a few weeks now it’s frozen, any ideas? I’m losing my mind over here
