How to Troubleshoot & Replace Samsung AP5648803 / DE92-03045A Pcb Main Assy

I replaced the Pcb Main Assy, in other words, the computer board that houses the clock face and cooking temp face. It really is an easy fix for those who have any mechanical abilities. Mention was made by another about the "flex cable" on the left of the board. NOTICE, the little black keeper does not completely remove, it only slides up just a touch and then the "flex cable" can be gently pulled from the connector. The only other connections that gave me a puzzle for a moment was the 2 "metal" connectors on the bottom left of the board. They have a tiny "release" within the clip, under the plastic hood, that must be pressed in order for the clip to release from the lug. Other than that, anyone with reasonable skill should be able to do this themselves. 

As in any repair <<< disconnect the power cord supply from the wall plug completely >>>> Removed the cover screws on rear top panel, At this point examine the Board to be Installed and confirm the part id numbers match to insure you have the exact replacement board you need ...... Carefully disconnect all the plug in connectors - be careful to mark the original positions for re install... note there is one ribbon cable on left side that connects differently - open latch and pull out the ribbon - reverse install... make positive it is completely inserted all the way on re install . Note there is (2) screws on the transformer that needs to be removed prior to flexing control board loose from its hooks... Replaced the control board and display worked fine. 

Replaced Pcb Main Assy card. First card sent didn't have a display at all so I called customer service and they sent another card and it works great. 

Samsung sent someone for free to diagnose. We were hoping they'd cover the repair. The technician called back with a quote of $500 to replace board and wiring harness. AppliancePartsPros had the board for approx $115 and I was able to replace the melted connector on the wiring harness for $2. Many years ago I was an Aviation Electrician's Mate in the Navy, so I was on somewhat familiar ground. 

Changed the whole board and overlay 

Replaced the main PC board. Also replaced the membrane keypad - just in case that was a problem; but I think the original was okay. 

I had missing segments on the LCD clock display, it was a annoyance but otherwise the stove worked fine. Recently I noticed that my front right burner was getting my food way to hot even when it was set to low. At first I wasn't sure what was happening because it did not do it all the time. It turned out that these Samsung stoves have this problem when the switch that your knob is connected to goes bad. The element would come on and stay on, if your stove starts to act this way you should stop using that burner until you can replace the switch. Be sure to take pictures of the wiring so you won't have any problems hooking the connectors back up. There are several videos on the internet you can watch so that you will help you understand how to disconnect the ribbon cable and other connectors. 

Replaced the pcb main assembly board and the right infinity energy regulator (burner control switch).
