CAUTION

All electrical parts and wiring must be shielded from torch ame. DO NOT allow torch to touch insulation; it will char at 200°F and ash ignite (burn) at 500°F. Excessive heat will distort the

plastic liner.

FREEZER ICE MAKER INFORMATION

(Where Applicable)

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 complete the cycle.

Water Fill Volume: The water ll adjustment screw will change the ll time. One full turn is equal to 20cc (.68 oz.). The correct ll is 102 to 130cc (3.4 to 4.3 oz.). When a water valve is replaced, the ll volume must be checked.

Notes:

• Always check for pin back-outs, pinched or damaged wires before replacing components.

• Determine whether failure is caused by the component, main control board or wiring. Contact TID before replacing main control board.

• Refer to Service Manual for additional information.

Check resistance between terminals 1 and 2, 2 and 3, 3 and 1.

If all resistances are equal,
