  If the compressor won't run, it could be due to several reasons. First, the overload might be open, in which case you should check and correct the cause. Another possibility is that the pump motor is off, so you should start it. Check the thermostat settings and set it properly if it's too high. Also, low line voltage could be the issue, so check and correct it. Finally, safety devices might be open; in that case, check the cause and reset them.

  If the pressure switches are tripping frequently, it might be due to several reasons. First, check and adjust the water flow or temperature, as improper condenser water flow or temperature can cause this issue. Another possibility is that the condenser tubes or coil are dirty, so clean the condenser. Also, improper entering air temperature could be the cause, so check and adjust it. Finally, a low refrigerant charge might be the problem, so add refrigerant.

  A ratting or squealing noise in the fan section could be due to a few reasons. The bearing might be broken and needs replacement. The fan could be rubbing against the housing, so fasten the fan wheel to the shaft. There might be foreign matter in the fan housing, so remove it. The belt could be loose or worn, so adjust the tension or replace it.
