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.

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.

CAUTION

Always purge the system with nitrogen. NEVER USE AIR to

purge the system.

Always recover the refrigerant.

When recharging, do not leave a line tap in the refrigeration

system because of possible corrosion or leakage problems.

Access the electrical and refrigeration components by removing

the sixteen screws on the back of the refrigerator (See Appendix

D, Replacement Parts).
