Parts for Maytag MMV4207JB0: Interior And Ventilation Parts

This magnetron capacitor is the microwave high-voltage capacitor that helps supply the magnetron with the pulse of energy needed to produce heat. Replacing a failing capacitor restores normal heating performance and reduces arcing or loud humming. What it does

• Stores and releases the high-voltage pulse required by the magnetron so the microwave can generate heat.
• Prevents unstable magnetron operation that can cause weak or no heating.
• Common symptoms of a failing capacitor: oven runs but doesn't heat, intermittent heating, loud buzzing/humming, or visible arcing inside the cavity.
• A failed capacitor can also cause blown internal fuses or tripped circuits.

• One capacitor.

• Disconnect power and verify the appliance is completely de-energized before servicing.
• Capacitors can hold dangerous charge; discharge the capacitor safely with an insulated tool.
• Use the exact replacement part and follow the appliance service manual for routing and connections.

This oven temperature sensor senses cooking cavity heat and sends accurate temperature readings to the range control so your oven can reach and maintain set cooking temperatures. Replaces a failed or intermittent sensor for consistent performance. What it does:

• Detects oven cavity temperature and relays readings to the controller
• Helps the oven maintain set temperatures for proper cooking and baking
• Common fix when oven won't heat correctly or displays inaccurate temps

• One oven temperature sensor (W10557536)

• Disconnect power to the appliance before servicing to avoid shock
• Handle the sensor and connector carefully; avoid bending or crimping the probe
• Verify connector type and routing match your model before final assembly

The Interlock Switch is an OEM part for Whirlpool microwaves. It monitors the position of the microwave door and signals to the control board whether it is safe to operate. 

Causes of a bad interlock switch can include normal wear over time as the switch contacts open and close frequently with door usage. Lubricant breakdown or damage to wires/connectors may also cause failures.

Symptoms of a faulty interlock switch include:

• The microwave running with the door open 
• Failure to start the microwave regardless of door position
• Inoperative door or faulty door latching 

Replacing with this genuine OEM switch restores an essential safety feature. With accurate door monitoring, microwave energy transmission only occurs when intended.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.
 

This thermistor is a refrigerator temperature sensor that monitors internal air temperature so the control board can regulate cooling. Replaces a failed sensor to help restore accurate temperature readings and more consistent cooling. What it does:

• Senses internal refrigerator temperature and sends a variable resistance signal to the control board
• Helps the control system cycle the compressor and fans correctly for stable temperatures
• Commonly replaced when refrigerator runs too cold, too warm, or has irregular cooling cycles
• Can address temperature-error codes or defrost control issues when the sensor is faulty

• Disconnect power to the appliance before inspecting or replacing the sensor
• Handle the sensor and wiring harness carefully to avoid damage to the probe or connectors
• Install in the original sensor mounting location and secure wiring away from moving parts

The Light Socket is an OEM replacement part for Whirlpool microwaves. This socket holds and supplies power to the light bulb inside the microwave, illuminating the interior when the door is opened or when the microwave is in use. It ensures that users can easily monitor the cooking process and check the condition of the food.

Over time, the light socket can become worn out or damaged due to regular use, electrical surges, or the heat generated within the microwave. Corrosion or buildup on the contacts can also impair the socket’s ability to provide a stable connection to the light bulb, leading to intermittent or complete failure of the light.

Symptoms of a bad light socket include:

• The interior light not turning on when the door is opened or during operation
• Flickering or dimming of the light
• The light bulb frequently burning out
• Electrical arcing or sparking from the socket area

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

The 40W Light Bulb is an OEM replacement part for Whirlpool microwave ovens. It is a standard-size bulb designed to provide illumination inside the microwave cavity, allowing you to easily view and monitor the cooking or reheating process.

Symptoms of a faulty microwave light bulb include:

• Dimming or flickering light during operation
• Complete bulb failure or no illumination within the cavity
• Discoloration or physical damage to the bulb itself

Causes of a bad microwave light bulb can include normal wear and tear over time, electrical surges or voltage fluctuations, or physical impact or vibration during use.

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

This Whirlpool Microwave Interlock Switch is an OEM part specifically compatible with various Whirlpool microwave models. This safety component ensures that the microwave operates only when the door is securely shut, thereby preventing accidental exposure to microwave energy. 

The failure of microwave interlock switches is often due to mechanical wear, electrical faults, or alignment issues. A defective interlock switch can result in the microwave not starting, running with the door open, or displaying erratic behavior, all of which are serious safety concerns.

Symptoms of a failing microwave interlock switch include:

• The microwave does not start or operate intermittently.
• The appliance runs while the door is open.
• Sudden stopping of the microwave during operation.
• Unusual sounds when the microwave door is opened or closed.
• The control panel is unresponsive or behaves irregularly with the door closed.

This genuine Whirlpool OEM replacement part is compatible with Maytag, Jenn-Air, and Kenmore models.
