Thermostatic Switch Malfunction
Tip:
The low side gauge needle may fluctuate in a very narrow
range compared to a normal range. The compressor clutch
may be cycling on and off more frequently than it should.
The low side gauge needle may fluctuate in an above nor-
mal range as the clutch cycles. This may be an indication
that the thermostat is set too high (someone may have at-
tempted to adjust the factory setting). A new thermostat may
have been installed incorrectly (capillary tube not inserted
between the evaporator fins in the proper position).
Cause:
The thermostatic switch is not functioning properly or at
all.
Repair Procedure:
Replace the thermostatic switch. When you remove the
old thermostat, replace it with one of the same type. (They
operate in a factory preset temperature range.) Take care in
removing and handling the thermostat and thin capillary
tube attached to it. Don
·
t kink or break the tube.
Position the new thermostat capillary tube at or close to
the same location and seating depth between the evaporator
coil fins as the old one. Connect the electrical leads.
