Ronald T Lancaster , CA December 13, 2022 Appliance: Whirlpool Refrigerator WRF736SDAM12 Whirlpool Refrigerator Wrf736sdam12: Whirlpool ice maker not working. How to replace Refrigerator Ice Maker Assembly. I was able to find a YouTube video that showed how to replace the ice maker. It didn't appear too complicated so I ordered the part from my favorite site AppliancePartsPros.com. Like always I quickly received the replacement and was able to make the repair in about 45 minutes. Pretty easy and now we have ice again! Love this site!
