Tip & How-To about Maytag Trash Compactor Motor Switch - 780164

Trash Compactor Switch Repair p/n 780164 or777971

Before buying the replacement switch for $80-$100 try fixing it. I've done it and it took only 5 minutes. If you have the skills to replace the switch then you have the skills to fix it. The switch itself is very simple inside and probably costs about $3 to manufacture. Remove the switch from the compactor and disconnect all the wires. Instead of throwing it in the trash, open the switch by pulling the top half of the plastic shell off. You may need to use a small screwdriver to help with that. Once open note the position of the two contact sets. Snap a picture to help you remember how they are oriented if you like but it will only go back together one way. Remove one set of contacts and note the charred contact points. GENTLY, use a small, fine file or a piece of emery cloth to burnish the contacts so that they are smooth and bright. Be gentle! They don't have to look perfect just smooth enough to make good contact. Put the contacts back in the shell and repeat the process for the other set. Put the shell top back on and secure with a piece of tape. Reinstall the switch and reconnect the wires and you'll be good to go!In the time it would take you to order a new switch you can fix the one you have and save yourself a hundred bucks on a grossly overpriced part.
