8.11 Servicing the
Refrigerator
Before servicing the refrigerator, disconnect it from power. This
precaution will protect you from the possibility of electric shock
when working with the refrigerator.
8.11.1 Electrical System Access the electrical and refrigeration components by removing
the nine screws on the back of the refrigerator (See Appendix D,
Replacement Parts).
WARNING
Removing the front or back panel exposes electrical and
mechanical hazards. Disconnect the power before
performing any service activities. Troubleshooting and
repair activities should be performed by a qualified
refrigeration technician.
The temperature control box assembly, which houses the ther-
mostat logic circuit board, the transformer, and the solid state
relay, is located on the left-hand side of the refrigerator base as
shown in Figure 8-5. Access to these components can be gained
by removing the four screws securing the lid of the temperature
control box. See Figure 8-6.
You can remove the temperature control box from the refrig-
erator by removing the screws from its mounting plate and dis-
connecting the wires from the backside of the box. See Figures
8-7 and 8-8.
