Mmv4250ba Parts

The High Voltage Capacitor is an OEM part for Whirlpool microwaves. This component allows the microwave to store and discharge high voltage current to the magnetron tube for generating microwave energy. 

Symptoms of a faulty capacitor include:

• Slow or incomplete cooking even on high power levels
• Inconsistent or uneven heating inside the microwave cavity  
• Sparking, burning or smoke emitting from inside components
• An appliance that fails to start or runs intermittently

Causes can be regular wear and tear over many years of use. The capacitor endures heat stresses each time the magnetron operates.

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