How to Troubleshoot & Replace Samsung AP5272126 / DE34-00330D Microwave Touch Pad Membrane Switch

Simple repair - removed defective piece & installed replacement part. 

After searching the internet ran into the AppliancePartsPROS.com website, Found that the problem was the "switch mambrane". I ordered it and received it withing two days as expected. The part was easy to replace and seems to have slolved the problem, microwave is working fine. 

I replaced just the membrane. Unplug. Then remove two Phillips screws on top of the vent/diffuser, shift slightly and remove. Then remove one screw holding the touchpad. Lift up then out. Gently remove four connectors and the ribbon connector on the board and the touch pad is free. Remove three or four screws holding the circuit board to the metal bracket inside the plastic touch pad housing. Remove the metal bracket by gently separating the plastic tabs. A knife or small flathead can be used to pry a corner of the old membrane up then peel it off. It is about as thick as a credit card but flexible. Run the ribbon connectors through their slot and adhere the peel and stick new membrane. Reassemble in reverse order. 

I ordered the control panel and switch membrane. Replaced the control panel and microwave works great! I'll be keeping the switch membrane just in case we have any more issues with our microwave. Shipping was insanely fast, ordered on a wednesday during lunch hour and received the parts the next day before lunch and hubby had the install done in just a few minutes!
