REMEDY
 Replacement of the expansion valve.
 Repair leakage and add refrigerant
gas.
 Replace the thermal switch.

Replace the system with a more
powerful one.
 Lower the load and improve insulation if
possible.
 Run a defrosting cycle.
 Identify the heater and eliminate it.
 Clean the condenser.

Replace the condenser with a correct
one.
 Replace it with a correct relay.
 Reassemble the relay in its correct
position.
 Replace the condenser with a correct
one.

Adjust properly.
 Replace the expansion valve with a
suitable one.
 Replace, increasing the evaporator
surface.
 Improve air circulation.

Adjust the valve or replace it with a
properly sized one.
 Clean the valve of any foreign
substances or replace it if necessary.
