Joshua M Portsmouth , OH September 27, 2016 Appliance: Model SAMSUNG FE-R300SW/XAA Oven not heating/ e 08 error code Replaced main PCB, everything working like new. Really easy repair, only tool required was a Phillips screwdriver. These guys ship faster than anyone I have ever ordered from. Less than 2 days from order to door both times I have ordered parts from them. Highly recommend. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
