Remove the two thermostat leads and place

them together using electrical tape. This will

by-pass the thermostat from the electrical

circuit. If the refrigerator begins operating

when the leads are by-passed, the thermostat

is defective and must be replaced. Be careful

not to touch any surrounding metal parts with

the thermostat lead ends when performing this

procedure, as this will needlessly blow the 3

amp. protection fuse.

The main switch contains many different

functions in the A.E.S. refrigerators, which

includes controlling the heat sources. In this

section we will discuss the troubleshooting

procedures for the entire switch functions,,

including the mode switch lamps as well as the

function lamps. Before gaining access to the

switch, visually inspect the switch cable for

any cuts or shorts. Check to see that the plug

connector is properly inserted into the

printed

circuit board connection.

Next, disconnect the positive and negative

battery leads from the terminal block. All of

our diagnosis on the switch will be made with

continuity or ohm’s resistance. Failure to

disconnect the DC power supply during

diagnosis could result in switch failure if it

inadvertently touches metal.
