PROBLEM
CAUSE
REMEDY
6.11 Compressor starts and continues
to run until
freeze up and will not cut off.
A. PCB malfunctioning or faulty ice
bank probe.
B. Ice bank probe positioned
improperly.
C. Ice bank probe shorted to ground.
A. Disconnec ice band probe from
PCB.
1. If compressor continues to run,
replace PCB.
2. If compressor stops, replace ice
bank probe.
B. Check positioning of ice bank
probe, and replace if needed.
C. Replace ice bank probe.

problem persists:
1. Determine reason and correct.
2. Electrical circuit overloaded;
switch to another circuit.
D. Measure voltage across common
and run terminal on compressor. Volt-
age must not drop below 90% of rated
voltage.
E. Replace PCB assembly.
F. Refer to wiring diagram and correct.
G. Replace ice bank probe.
