Component Voltage Test - Monogram ZET1PL1SS Technical Service Manual

Component Voltage Test

The voltage applied to certain components can be tested individually. Enter the Service Test Mode and
select the step for the operation of the desired component. Check for proper voltage on the relay board as
described in the table and shown on the diagram below.
Note:
• N (Neutral) can be measured from the J7 terminal on the relay board or from the U12 connector on the
Power Supply board.
• L2 can be measured from the orange wire on the common terminal C of the Double Line Break relay or
on the black wire at the 240 VAC power harness.
