The Harness Assembly is an OEM part for GE dishwashers. It contains multiple electrical wires and connectors that transmit power and signals throughout various areas of the dishwasher. This includes distributing power from the control board to components like motors, heating elements, and sensors located in the base and tub. 

Proper wiring is essential to ensure these parts receive the correct voltage to operate as intended. The harness routes electrical signals back to the control board to communicate cycle progress and diagnostics.

Symptoms of a bad harness include:

• Motors, heating elements, or other components failing to activate 
• Inability of the control board to monitor cycle steps accurately
• Intermittent electrical connections causing unreliable operation

Causes can be cracked insulation, loose connections due to repetitive component access, or damage over time from water, detergent, or other contaminants. 

This part is compatible with Hotpoint, RCA, and select Kenmore models.
