Burt N Mesa , AZ August 07, 2021 Appliance: Model 795.775436000 Interior lights not working. After I paid a tech to repair the lights not working in the fridge and after $400.00 to replace the switches they still didn't work. He said I need to replace the main circuit board and that would be around a $1,000 dollars to to that. I found the circuit board and replaced it myself for under $150.00 and 15 minutes of my time. The lights are working now 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
