Parts for Maytag MMW9730AB01: 02 - Control Panel Parts

Fix an oven that won't heat, has error codes, or unresponsive controls with this electronic control board. Moderate difficulty repair for most models.

This power supply is the electronic control board that provides the regulated voltages and control signals needed for the appliance's user console and main controls to operate reliably. It restores proper power distribution so controls can respond. What it does:

• Converts incoming AC to the low-voltage DC used by the console and control circuitry.
• Powers display, buttons, and control relays so the appliance can receive and execute commands.
• Common symptom: blank or unresponsive display/console.
• Common symptom: intermittent or total loss of control functions, or failure to start cycles.

• Disconnect power before servicing to avoid electrical shock.
• Handle the board by its edges and avoid ESD (static) damage—use proper grounding.
• Reassemble panels and secure connectors fully; test control functions after installation.

The blower wheel is a fan component that moves air through your appliance, whether circulating heated air in a dryer or pushing conditioned air through a refrigerator or HVAC system. It spins at high speed to maintain consistent airflow throughout the cycle. Replace this part if your appliance is noisy, vibrating excessively, or not moving enough air to heat or cool properly.

A shoulder screw that secures appliance components and provides a precise pivot or spacer point. Replaces a missing or worn screw to restore alignment, reduce rattling, and keep panels and assemblies securely in place. What it does:

• Provides a fixed-diameter shoulder for pivots, spacers, or mounting points in assemblies.
• Holds panels and moving components at the correct distance to prevent binding or friction.
• A missing or worn shoulder screw can cause misalignment, rattling, or loose parts during operation.
• Used where a smooth-bearing surface and controlled clearance are required between parts.

• Disconnect power to the appliance (unplug or shut off breaker) before servicing.
• Handle small fasteners carefully to avoid dropping into assemblies; magnetic pickup tools can help.
• Start threads by hand to avoid cross-threading; tighten snugly but avoid overtightening.

This foam seal fits between mating parts to create a tight barrier that helps prevent leaks and rattling. Replacing a worn or missing seal restores proper sealing and helps keep your appliance running quietly. What it does:

• Creates a compliant gasket between components to limit air or moisture passage
• Helps dampen vibration and reduce rattling/buzzing where parts meet
• Helps maintain proper airflow or fluid routing as designed
• Typical symptoms include leaks, condensation/frost near a joint, or new vibration noises

• One foam seal

• Disconnect power; turn off the water supply before service
• Note the original seal's routing/orientation before removal
• Clean and dry all mating surfaces; remove old foam and residue
• Install without stretching or over-compressing; ensure even contact with no gaps
