Replace all three door switches with these

If it is a post 2013 Frigidaire or Kenmore replace this as well

Don't forget to transfer the little flipper fidget from the bottom between the two switches.

The switches all have three terminals. Just make sure the wires go back on the same terminals.

I was able to source all the parts on Amazon domestically except the relay, which either has to come from a parts specialty place, or from a Chinese seller on Amazon marketplace or eBay.

Primary door switch: https://smile.amazon.com/gp/product/B002CRSOR0/ (use only the bottom of the two side terminals and cover the other with electrical tape; this is the one recommended by u/HeadOfMax)

Replace the switch. It will give you trouble again. It's $7.
