Tim M Hanford , CA October 27, 2017 Freezing up in the refrigerator water running onto floor Replaced heater, thermo switch bi - metal switch. The replacement parts didn’t have the correct connectors so I removed the old ones and soldered them on the new parts( I am an aircraft mechanic by trade). All went well , works great! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
