6.2: Main Control Board
WARNING
Prior to removing the access cover to the machine compartment, disconnect the
supply voltage to the appliance; failure to do this could result in an electrical
shock or possible death.
CAUTION
It is recommended that a grounding strap be used when working with any solid
state control board application.
6.2.1: Control Board Replacement
1. The main power board is located at the bottom rear, left hand corner of the machine
compartment.
2. To replace the board, remove the Phillips head screw securing the mounting bracket to
the machine compartment.
3. For ease of access, lower the leveling leg so that the threaded section is lower than its
threaded bushing.
4. Remove both large connectors on the bottom left hand side of the control board. Press
the release and pull each connector off its terminal.
5. The board can now be lifted out of the machine compartment.
6. The main board mounting bracket and the machine compartment bottom are
manufactured for a positive fit upon installation.
a. The control bracket has a notched recess on the bottom rear of the bracket.
b. The machine compartment bottom has a slotted tab to facilitate the recess of
the control mounting bracket when installed.
7. Each wiring harness at the board is labeled as to its corresponding location on the
board. Prior to removing any harness, double check to insure that the identification on
each harness is legible for correct placement when repair in completed.
8. The control board terminals are also marked as to the correct harness locations.
