Marc B Port Orange , FL February 18, 2018 Appliance: General Electric General Electric GSH25JSDBSS Ge Refrigerator Gsh25jsdbss / : Front door would no longer dispense cold water. How to replace Refrigerator Main Control Board. After some simple troubleshooting, determined that it was likely the (rear) main control board. Once the new board arrived, it was installed in 5-10 minutes once the refrigerator was pulled out from the wall and the area cleaned up a bit. My only negative feedback was that delivery was too slow by today's standards. Fedex Post was used and in my experience it usually adds an extra 2-days compared to other ground shipping methods. The part was ordered on Sunday night. It shipped out of Georgia on Monday but the USPS delivered to me in central Florida on Thursday. That is very slow considering that Central Florida is only a few hours north of Daytona. Most of the delay was with FEDEX. USPS has become quite fast and efficient in recent years. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
