board

BLU "H3-4" to "H3-6"

NOTE: All checks in this flow chart are based on the assumption a high speed agitate and spin cycle have been selected.

(#) Numbers next to voltage checks correspond to the locations marked on the wiring schematic.

After checking for correct wiring, refer to Section 7 or Paragraph 6.
