To fix this problem you'll need to do the following:
- Check the outdoor unit is clear of any obstructions, the outdoor unit requires good air flow to keep the coils clean
- Check the outdoor unit sensors are connected the PCB correctly
- Check the sensor sockets are clean, these sensors are exposed to condensate water so the sockets can corrode, clean the sockets with a small light abrasive brush
An engineer will be needed to check the refrigerant level is correct if the sensors are not a fault
