PROXIMITY SWITCH VOLTAGE CHECK
3 Relay Circuit Board Proximity Switch Check Procedure
NOTE: These checks should be done with proper
line voltage.
Set the multi-meter to read D.C. voltage - turn the
ice machine toggle switch to the center (off) position.
Disconnect the Red, White and Black leads of the prox-
imity switch from the control board. Turn the toggle switch
to the up position (ice). Check for voltage at the positive
and negative terminals on the control board.
NOTE: Voltage above 24 VDC will damage proximity
switch - replace both the control board and
proximity switch.
Voltage below 13 VDC proximity switch will
be intermittent - replace control board.
