Whirlpool 99002739 Middle Arm Assembly Oem

Product Description

The WHIRLPOOL 99002739 is an OEM middle arm assembly designed as a direct replacement for compatible Whirlpool dishwashers. The middle spray arm distributes water across the interior during wash cycles, directing flow to both the upper and lower rack loads. When the arm cracks, clogs beyond cleaning, or breaks at the hub, water distribution becomes uneven and wash performance drops. This part restores proper spray coverage to the mid-zone of the dishwasher tub. Installation is handled by appliance technicians or experienced DIYers during routine dishwasher repair service.

This middle arm assembly fits within the dishwasher tub, mounting between the lower and upper rack positions. It is intended for residential Whirlpool dishwasher models where the original middle spray arm has failed or degraded. No specific compatible model numbers are listed in the available product data. Verify the part number against your unit's model and serial tag before ordering to confirm fitment.

Key Features

• OEM part manufactured to original equipment specifications
• Direct replacement for a failed or damaged middle spray arm
• Restores even water distribution across the mid-rack zone

Compatibility

Designed as an OEM-style replacement middle arm assembly for compatible Whirlpool residential dishwashers. Confirm fitment using the model and serial number located on the dishwasher door jamb before installation.

Installation Notes

Disconnect power to the dishwasher at the circuit breaker before beginning any internal service. The middle arm assembly typically snaps or threads onto a central hub mount inside the tub and requires no special tools for removal or installation. Inspect the hub fitting and water feed port for debris or damage before installing the new arm. Appliance technicians should follow manufacturer service documentation for the specific model being serviced.
