I un-screwed light bulbs to keep refrigerator from getting so hot.. Repairman called in a few days and said parts unavailable. I asked for refund but they told me that was for diagnosis...duh! I looked on internet and found your website and videos. Ordered new switch which came in the next day. I replaced switch, removed light bulb holder and cleaned it up. Installed it and is working perfectly. Found a new light bulb holder on eBay and ordered in case the old one goes bad. Thanks for video and switch!
