12 SERVICING PROCEDURES
12.1 Safety Considerations
CAUTION
ALL TERMINALS AND INTERNAL PARTS SHOULD BE
TREATED AS LIVE.
ALL SERVICING SHOULD BE CARRIED OUT WITH THE REFRIGERATOR
DISCONNECTED FROM THE POWER SUPPLY.
Before servicing this appliance, your body should be at the same voltage potential.
An antistatic wrist
strap must be used when handling electronic components.
Printed circuit boards removed from the refrigerator for return to Fisher & Paykel must be protected from
possible electrostatic damage (ESD) while in transit by the use of the specialised packaging in which the
replacement was received.

12.2 Electrical Safety Test
Whenever any part of the electrical circuit is serviced or disturbed in the course of carrying out service
adjustments or procedures, it is essential that an insulation and earth continuity test be carried out using a
two-scale megger. This is to be done with the appliance disconnected from power.
Insulation:
At least 1 megohm
Earth Continuity:
No greater than 0.5 ohm
NOTE:
Electronic printed circuit boards can be damaged if meggered incorrectly as phase / earth or neutral
/ earth.
Therefore to carry out an insulation megger test where the appliance is fitted with a electronic printed circuit
board, short out both the phase and neutral conductors together at the 3 pin plug with one test lead of the
megger. Connect the other lead of the megger to the earth / cabinet of the refrigerator under test.
Earth continuity can be measured between the earth pin on the 3-pin plug and the cabinet of the refrigerator.
