Removing the Control Box

The Control box is attached to the bottom of the divider wall separating the freezer and refrigerator

compartments. The control box contains the defrost timer and the operating thermostat.

the separator.

2. Pull the control box forward to release the two (2) tabs securing the back of the control box

to the bottom of the separator.

3. The control box can now be dropped down to allow access to the defrost timer and the

thermostat.

Servicing the Defrost Timer

There are two different types of defrost timers, depending on the model being serviced. Figure 27

shows an Electronic Defrost Control. Figure 28 shows a typical Electromechanical Defrost Timer.

Both types of defrost timers are secured in the control box with the same mounting screws as

shown in Figure 28.
