Whirlpool W10422269 Microwave Noise Filter Board

The Whirlpool W10422269 is an important component for your microwave, serving as a noise filter board. Consider it a little gatekeeper for electricity. Microwaves require a precise voltage to operate correctly. This board regulates incoming household current, lowering it to a level that the microwave's sensitive internal components may safely and efficiently use.  A defective noise filter board may prohibit your microwave from starting at all. Despite its modest size, it is critical to the effective operation of your microwave. The good news is that this part is interchangeable with many Whirlpool models and can be purchased as a replacement if your appliance is no longer working owing to a faulty noise filter board.
