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.

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 fill adjustment screw will

change the fill time. One full turn is equal to 20cc (.68 oz.).

The correct fill is 102 to 130cc (3.4 to 4.3 oz.). When a water

valve is replaced, the fill volume must be checked.
