Diagnosing Electronic Control Boards
Diagnosing the main control and UI control are
covered in this section. Many components can
be checked from the main control, which can be
accessed with the door on or removed if needed.
Some connectors are located through the bottom
cover to allow easy access to AC supply connector,
door harness and ACM or Appliance Control Module.
The ACM or Smart Appliance allows the appliance to
communicate with the utility meter when peak rates
occur, and allows the appliance to respond and
operate in a manner that will reduce energy usage
of that appliance at high/critical demand rates. For
more on the module and display, refer to Smart
Appliance documents.
WARNING: GE Factory Service Technicians are
REQUIRED to follow Lockout / Tagout (LOTO) 6
Step Process prior to beginning repair.
