If all resistances are equal,
compressor is operative.
All electrical parts and wiring must be shielded from torch flame. DO NOT allow torch to touch
insulation; it will char at 200°F and flash ignite (burn) at 500°F. Excessive heat will distort the
plastic liner.
FREEZER ICE MAKER INFORMATION
Test Cycling: Remove cover by inserting screwdriver in notch
at bottom and prying cover from housing. Use screwdriver to
rotate motor gear counterclockwise until holding switch circuit
is completed. All components of ice maker should function to
