Remove the two thermostat leads and placethem together using electrical tape. This willby-pass the thermostat from the electricalcircuit. If the refrigerator begins operatingwhen the leads are by-passed, the thermostatis defective and must be replaced. Be carefulnot to touch any surrounding metal parts withthe thermostat lead ends when performing thisprocedure, as this will needlessly blow the 3amp. protection fuse.(101)The main switch contains many differentfunctions in the A.E.S. refrigerators, whichincludes controlling the heat sources. In thissection we will discuss the troubleshootingprocedures for the entire switch functions,,including the mode switch lamps as well as thefunction lamps. Before gaining access to theswitch, visually inspect the switch cable forany cuts or shorts. Check to see that the plugconnector is properly inserted into the printedcircuit board connection.(102)Next, disconnect the positive and negativebattery leads from the terminal block. All ofour diagnosis on the switch will be made withcontinuity or ohm’s resistance. Failure todisconnect the DC power supply duringdiagnosis could result in switch failure if itinadvertently touches metal.A-4-35
(103)Refer to the RM3801 switch diagnosistroubleshooting section of the A.E.S.Diagnostic <strong>Manual</strong> for a detailed explanationon how to troubleshoot these switches. (Seepages A-8-l to A-8-5)(104)The next component to diagnose is thesolenoid valve’s internal winding. The A.E.S.control system uses the solenoid winding toprovide a ground circuit to the printed circuitboard for all modes of operation. If thesolenoid winding is defective, the refrigeratorwill not operate on any heat source.(105)To check the solenoid winding, remove allpower sources from the refrigerator, AC andDC and unplug the connector at the solenoidby pulling firmly outward.Measure the resistance value across the upperand lower terminals on the valve assembly.The proper valve should be 20 ohms withtolerance range of 10 percent. Values outsidethe tolerance range or no ohms reading wouldindicate a defective solenoid valve winding.A-6-36
