Parts for Maytag MMMF6030PW00: 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.

The Diode is an OEM part for Whirlpool microwaves. The diode plays a key role in regulating power flow and protecting other sensitive components from voltage fluctuations.

Causes of a bad microwave diode can include component failure due to age or heat exposure over time. Diodes are also susceptible to electrical damage if exposed to power surges.

Symptoms of a bad diode can include:

• The microwave failing to power on or having intermittent power
• Food not heating up properly or unevenly
• Strange sounds like buzzing or humming emanating from inside
• The door lock mechanism not engaging or release properly
• Repeated tripping of fuses or circuit breakers

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

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

This replaceable refrigerator water filter cartridge helps restore clear, better-tasting drinking water and ice by capturing sediment and common impurities. Designed for a quick swap to keep your fridge dispensing clean water. What it does:

• Filters sediment and particulate to reduce cloudiness in water and ice
• Helps improve taste and odor commonly associated with older filters
• Restores normal water flow and delivery when a clogged filter causes slow dispensing
• Supports routine maintenance to help prevent scale and buildup in the dispenser system

• Shut off the refrigerator water supply before removal to limit spills
• Follow the refrigerator manufacturer's removal/installation motion (push, pull, twist, or bayonet style)
• Flush several full glasses of water after installation to clear air and initial carbon fines
• Check for leaks at the filter and housing after restoring the water supply; discard the old filter per local regulations

This is a thermal safety fuse that opens the circuit if temperatures rise beyond a safe limit, protecting the appliance from overheating and preventing further damage. Replacing a failed fuse restores power to the affected circuit once the underlying cause is addressed.

• Monitors temperature in a protected circuit and cuts power if unsafe heat is detected
• Helps prevent overheating-related damage
• Typical failure signs: no power/no operation, cycle won't start, shuts off mid-cycle after overheating event
• Must not be bypassed; replace if open and investigate the root cause of overheating

• Unplug appliance or disconnect power before service
• Verify the fuse is open with a multimeter; replace only after correcting any airflow/overheating issues
• Install in the same orientation and location as the original to ensure proper temperature sensing
• Handle wiring carefully; transfer connectors one at a time to avoid miswiring
