Question about Samsung MD800SC Microwave Oven
What i did here is very dangerous and nobody should ever try this. because: i have a friend who ,15 years ago, lost a bet and burned up 2 fingers messing with the voltage in a junk microwave. it is deceptively high and incredibly destructive and lethal. he woke up in the hospital and to this day calls hi right hand "the claw" lol... hmmm.. hes a great person.. but now he hates microwaves and gets nauseous at at the sight of one that not in use. ********i made a homemade key pad. ********** first i pinned out the key pad matrix, then i soldered cat5 strands to the ribbon receptacle.( on the display board ) then stripped and soldered 5" lengths cat5 strands on to 3 "clicky buttons"(i got from a dead car stereo face) then i cut a 1"wide 2" tall piece of 1/8" thick pvc plastic to fit over the old keypad to mount the new clicky buttons on. then i heated the ends of the clicky button wires with a mini blowtorch and melted the red hot ends of the wires threw the plastic home made button mount one at a time. then i scotch taped taped the plastic to the face of the microwave over the disconnected keypad . then straitened the wires so they were uniformly and adequately sepperated wile using a 2" wide 4" long piece of scotch tape to take them to the plastic face of the microwave. and around the right end of the the plastic face to the back of the plastic face. i put about 4 or 5 layers of tape to ensure insulation from the metal frame. then i mated up the wires and trimmed the excess wire. then i soldered the mated corresponding wires together where they were mated. then i reassembled the button pannel thing and tested it. (shielding my face with one hand to deflect any exploding electrolytic caps that may explode!.. lol.. it didn't blow up) then i put all the screws back in and put the cover back on and tested it again. then i labeled the new button pannel with a piece of paper laminated in 2" scotch tape and scotch taped it beside the buttons on the right with another 4 layers of 2" scotch tape. works perfectly.
