Very easy fix to eliminate the SE error...Hopefully permanently. APP shipped my part so fast it basically arrived the next day without paying for overnight delivery. For about $40, my microwave is up an running again. I tried all the other non-part fixes and none worked for more than a day. The fix was simple. Remove the two screws holding the vent. Push vent to the left and with the micro door open, pull out from the micro. Next, remove the one screw holding the control panel. Push the control panel up and away from micro. Disconnect the wire harnesses and remove panel completely. Next, remove the ribbon cable by pulling up on the white portion of connector. Do not pull the ribbon cable out until you have unlocked it from the circuit board by gently pulling up on the white connector. Now remove the 4-5 philips head screws holding the circuit board and remove. Remove the board and set to the side. Next, place a screw driver between the plastic control panel and the aluminum housing. There are four retention tabs, so pull up on the aluminum housing as you release them with the screw driver. There will be metallic ribbon ground attached to the back of the aluminum housing that simply hooks onto the housing. Once you have the aluminum housing removed, you can use a small screw driver to pry up the touch panel on the front of the control panel. It will likely separate as you pry it off, but you need to remove the entire touch panel until you are down to the plastic base. Watch as the LED cover is now lose and can fall out. Just put it back in if it does, but be sure it's in place before placing the new touchpad. Clean all the excess glue off with goo gone or something similar. DO NOT REMOVE THE ADHESIVE COVER ON THE NEW TOUCHPAD YET. Once the housing is clean, you'll need to slide the two ribbon cables through the slot in the housing. Do the small part of the larger ribbon cable first. Once you get the larger ribbon cable partially through, you'll need to shift it up to then fit the larger portion of the ribbon cable through and also the grounding ribbon. Position the edge of the new touch pad and test fit it on the housing. If all looks good, put the edge closest to the ribbon cable into position,and then remove the adhesive cover. Lay the touch pad down slowly. You only have one chance to get it aligned. Thuroughly press the pad down so it's nicely secured. Now you can re-install the aluminum housing. Start by hooking the grounding ribbon cable to the back of the housing. This ribbon cable does NOT come through the slot in the aluminum housing. It hooks to the back. Now feed the ribbon cable through the slot in the aluminum housing. Now your can push the aluminum housing down until it snaps back into position. This may take a little time to get it to snap back in, but it will go. Gentle pressure should do it. Now you can place the circuit board back into place and fasten with screws. Attach the ribbon cable by gently pushing into the connector until it stops, then push down on the top of the white connector. The cable should now be secured. You are now ready to reinstall the control panel. Attach all the wire connectors and re-install. Now you can place the vent cover by inserting and pushing to the right. Attach with screws. You are now ready to plug in micro and start cooking! So much easier and cheaper than buying a new one. Appliance Part Pros is an awesome website!
