reduced capacity
10. Moisture in System
1. Faulty wire
connection
2. Faulty Thermistor
3. Program Issue
Remedy
6. Remove thermistor, check in ice
water and compare to thermistor curve
chart. If faulty replace, if thermistor
tests o.k. check wire harness
connections. If all connections are
sound possibility of control board
issue. (Contact Electro Freeze Factory

contactor for proper operation,
and possible voltage drop, ohm
compressor windings to check
for a short and proper winding
resistance, check compressor
starting components for failure, allow
compressor protector to reset and
check for proper amp draw.
10. Recover refrigerant, change filter
drier, change compressor oil (Contact
Electro Freeze for proper compressor
oil charge), Evacuate system to a
minimum of 200 microns or less.
Repeat if necessary
1. Locate faulty connection (Wire
