Verify drum rotates freely by hand (no bearing seizure) – should complete 3+ rotations when spun.
Inspect drive belt tension and condition – replace if glazed, cracked, or stretched (proper tension: 1/2″ deflection with 10 lbs pressure).
Check suspension rods for proper tension (all 4 should have equal resistance when pulled down 2 inches).
Test hall sensor operation as per 3E procedure with drum rotation.
Measure inverter DC bus voltage during startup attempt with multimeter (should maintain >300V DC under load).
Replace main PCB DC92-01543A if DC bus collapses during startup attempt indicating faulty power components.
