Test Procedure Repair
Disconnect power. Remove both leads from the
switch and measure resistance across switch
terminals. Resistance should read less than 1 Ω in
this position and higher than 10 MΩ when switch
is open.
Disconnect power. Remove the cover of freezer
door hinge located on top of the unit and
disconnect the connectors. Check BU wire (pin 3
of 10-pin connector) for continuity.
With PCB powered, press the Main dispenser
switch. Measure voltage on pin 3 (BU wire) of 10-
pin connector. Voltage should read 120VAC.

Amana specifies a minimum supply pressure of 35 psig for water filter units. Minimum pressure
requirement ensures that water valves close and sufficient water volume is available to fill icemaker.
Proper fill is 140 cc. of water in 7.5 seconds. Failure of water valves to close because of low pressure
will result in fill-tube freeze-up or dripping at cavity.
