Parts for Maytag JMW2330WS00: 08 - Top Support And Turntable Parts

This power supply board, sometimes referenced as the SMS module, provides regulated low-voltage power for the appliance's control system. Replacing a failing board restores power to the controls so the unit turns on and runs reliably.

• Converts AC line power into stable low-voltage DC for control electronics and the user interface
• Distributes power to critical control circuits and relays
• Helps protect sensitive components from voltage irregularities
• Common symptoms: no lights or display, unresponsive controls, won't start, intermittent power loss

• Disconnect power at the breaker and verify no voltage is present before servicing
• Handle the board by the edges and use ESD protection
• Photograph/label connectors; transfer wiring one at a time to avoid misrouting
• Ensure all connectors are fully seated and the board is secured before restoring power and testing

The Turntable Tray is an OEM part for Whirlpool microwaves. This circular plastic tray sits atop the cavity within the microwave. The turntable tray is responsible for smoothly rotating food items during cooking cycles to ensure even heating exposure. It prevents hot and cold spots that can ruin prepared meals. The tray measures approximately 16 inches in diameter.

Causes relate to extended use over time, warping from high heat exposure, or accumulating residue that impedes free movement.

Symptoms of a worn turntable tray include:

• Inconsistent cooking results with some portions remaining underdone
• Squeaking or scraping noises emitting from below during operation
• The tray no longer spinning smoothly on its post seal track

This genuine OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

This turntable support ring sits beneath the microwave's glass tray and lets it roll smoothly during cooking. Replacing a worn or damaged ring restores stable rotation for more even heating and prevents tray wobble or binding.

• Supports the glass turntable as it rotates
• Provides a low-friction track for smooth, consistent movement
• Helps keep the tray level and centered during operation
• Typical symptoms: turntable not turning, uneven heating, grinding/scraping noises, tray wobbling or coming off track

• Disconnect power to the microwave before servicing
• Remove the glass tray and lift out the old ring
• Clean the turntable deck of debris before installing the new ring
• Center the new ring on the deck, reinstall the tray, and test rotation with a cup of water

The Turntable Coupler is an OEM part for Whirlpool microwaves. This part rotates the turntable, ensuring even cooking by moving the food inside the microwave.

Symptoms of a bad turntable coupler include:

• The turntable not rotating
• Uneven heating of food
• Grinding or clicking noises during operation
