Should have a dry contact on the board, cant remember what number (m4?), possibly loose wire or cut. Put a jumper and see what happens

Mr slim ac shuts down and restarts to frequently.


Changing the setting won't affect the way the unit works, only how long it runs for. Rapid switching off and on will kill your compressor in time - check the refrigerant level. Usually short cycling on lp switch.

Mr slim Mitsubishi - how much fill


On the data plate for the outdoor unit it will tell you what type and how much refrigerant you need. If the line set is longer than 25 feet you will likely need a bit more than what it says. A 40 degrees evaporator temperature is ideal, approximately 65 psi for r22
