How to replace a range oven door lock assembly

This range repair guide gives step-by-step instructions on how to replace the door lock motor assembly for a self-cleaning oven in a range. The door lock motor assembly locks the latch to keep the oven door shut during the cleaning cycle and when the control lock-out is active. If the door isn't locking, replace the door lock motor with the manufacturer-approved replacement part.

This repair guide and video shows how to replace the oven door lock assembly on Kenmore 790-series, Frigidaire and Electrolux ranges. You also can use the same basic repair procedure to replace the oven door lock assembly on some Whirlpool, KitchenAid, GE, Maytag, Amana, LG and Samsung ranges.
