Important note right up front: this switch is NOT UNIVERSAL! It's a specific replacement part for certain Whirlpool dryer models. If your dryer's push-to-start button isn't working, this might be the fix. The part number is W10117655, and it directly replaces the old part number 1448106 (also AH1491565, EA1491565, PS1491565). Fitting is crucial, so please check your dryer's model number against this list (it's long, but here are some examples): 7MMEDC300DW0, 7MMGDC300DW0, MED5600TQ0, MED5800TW0, MEDC300XW0, MET3800TW0, MGD5600TQ0, MGD5800TW0, and many more variations (the full list is in the description). If your model matches, this is the genuine replacement switch you need. Installation usually involves removing the dryer's console or control panel – if you're comfortable with basic tools and appliance repair, you can probably DIY it. If not, a technician can handle it quickly. Always unplug the dryer before starting any repair! This little switch is often the culprit when the dryer won't start with a push, so if you've ruled out the door switch and thermal fuse, this could be your solution.
