Frigidaire FFRERAMWDW189 Installation manual

Check at the connector from

the service cord into the

inverter (typically PUR and

WHT wires.)

Is Inverter receiving 115

VAC from power supply?

Check voltage supply.•Check and repair

service cord wiring

and connections.

IMPORTANT SAFETY NOTE

The information provided herein is designed to assist qualified repair personnel only. Untrained persons should not
attempt to make repairs due to the possibility of electrical shock. Disconnect power cord before servicing this appliance.

IMPORTANT

If any green grounding wires are removed during servicing, they must be returned to their original position and
properly secured.

CAUTION

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.

ICE MAKER INFORMATION

Test Cycling

Press the momentary contact on the ON/OFF switch for approximately 15 seconds. Ice maker
will continue to complete the cycle.

Water Fill Volume

The water fill can be adjusted without removing the ice maker cover. To adjust the fill size,
remove the small round plug next to the On/Off Switch. Insert a #2 Phillips screwdriver into
the hole about an inch or until it engages the Water Fill Adjustment Screw. Turn the screw
clockwise to reduce the fill size; turn the screw counterclockwise to increase the fill size. One
turn equals approx 20cc (0.68 oz). The correct fill is 85 to 95cc (2.75 to 3.25 oz). When a
water valve is replaced, check the fill volume.
