Refer to the RM3801 switch diagnosis

troubleshooting

section of

the

A.E.S.

Diagnostic Manual for a detailed explanation

on how to troubleshoot these switches. (See

pages A-8-l to A-8-5)

The next component to diagnose is the

solenoid valve’s internal winding. The A.E.S.

control system uses the solenoid winding to

provide a ground circuit to the printed circuit

board for all modes of operation. If the

solenoid winding is defective, the refrigerator

will not operate on any heat source.

(105)

To check the solenoid winding, remove all

power sources from the refrigerator, AC and

DC and unplug the connector at the solenoid

by pulling firmly outward.

Measure the resistance value across the upper

and lower terminals on the valve assembly.

The proper valve should be 20 ohms with

tolerance range of 10 percent. Values outside

the tolerance range or no ohms reading would

indicate a defective solenoid valve winding.
