How to replace a trash compactor power switch
This DIY repair guide explains how to replace the power switch on a trash compactor. Located in the control panel, the power switch turns on the trash compactor when you turn the knob. If the power switch breaks, the trash compactor won't start at all. Replace a broken power switch with the manufacturer-approved replacement part.
This repair procedure shows how to replace the power switch on Kenmore, Whirlpool, KitchenAid, JennAir and Maytag trash compactors.
