Chris O Port Orange , FL July 19, 2016 Appliance: Model SAMSUNG FR-R300SX Control board (error code e 28) We had a lightning strike on the house and it damaged our Samsung Stove. I initially ordered a new thermistor to replace the one that referenced the error code. It did not fix the problem. After more research it was determined that the control board needed replacement as well. I ordered replacement board from Appliance Pros and it was delivered a day and a half later!! These guys rock! The whole job took less than 10 min. We now have a functioning stove again. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
