Inspect wiring harnesses: Check all connectors to sensors, pumps, fans, and the control board. Reseat and secure them.
Check for heat damage: Look for discoloration or warping on the control PCB and surrounding plastic.
Test sensors under movement: Wiggle sensor wires while monitoring resistance with a multimeter to detect intermittent breaks.
