Suction pressure too low:
Refrigerant charge too low; add refrigerant.
Air circulation on the evaporator unit not sufficient;
check for the cause and repair.
Expansion device or suction line clogged: check and
repair.
Fan cycling due to its overtemperature protection:
Fan capacitor faulty; replace.
Electrical connections loose; check connections.
Fan bearing seized; check and repair.
Expansion device clogged or covered with ice; drain
