This electronic circuit board frequently experiences a specific failure mode where the transformer connection tabs or terminals fracture and separate, preventing proper power distribution. You can diagnose this issue while the unit is energized by applying gentle pressure to the transformer component—if you hear a relay activation sound, this indicates a broken terminal connection causing the power failure. Depending on severity, this condition may be serviceable through repair, or the control board can be replaced entirely.
