First, it was going to cost $95 for an appliance guy just to look at it! I figured there would be an upcharge on the parts + labor on top of the $95, so I took a chance & decided my husband & I could fix it cheaper; we were right, but it was a 3 week process (luckily, we have another microwave in the basement we were able to use in the meantime). I googled the microwave model #, then price checked the same item I thought we needed; printed off the diagrams of the various microwave "systems" & labeled them, so we knew what every item was called. Checked various websites for the best price (including shipping), before placing my order. In hindsight, I wish I would've opened it up first before placing our order (I would've seen the burned harness wire end at that time), so I could've ordered all possible parts at the same time to save on shipping costs + time; I would've just sent those I didn't actually need back afterwards. Anyway, I purchased a motor turn part online & after the part was received, I unscrewed the trim kit & removed it from cabinet base & then we gently flipped the microwave on it's head on a hard padded surface (towel on counter or table). We replaced the turntable motor in the base (used metal clippers around the outside base of metal shield/cage, replaced part by unplugging the old & replugging the new motor, then rotated shield door to slide brackets into place). Turned right side up. Removed exterior screws to slide off the entire outer stainless steel shell "walls", pulling away from the functioning door, backwards off the microwave (there are grooves, so when you go to put it back on, set the unit with the door facing flush with countertop, using 2 people to slide it on using even pressure & speed, placing pressure of base corners). Noticed harness wire end blackened & melted, while still plugged into the bottom door switch set. Ordered entire harness wire (couldn't find just one end for fix) & replaced, still didn't work. Ordered door interlock switch kit (2-pack) ) & replaced it & voila, it turned! Tested the original turntable motor & it still worked, so we swapped it back in & then sent the new motor turn back. Total costs: harness wire $48.41 + 2-pack door interlocking switch set @ $46.81 = $95.22!!! Same price as it would have been just to have someone tell me it's broken. However, the downside is that the refund on the 1 item I shipped back was originally $46.55 minus the $8.95 shipping costs + my $4.45 shipping costs to send back means U lost $13.40 on that deal! So actual cost were $95.22 + $13.40+ $108.62 when it's all said & done...still cheaper to do it ourselves.Decided to storing the original harness wire + 2nd unused door interlock switch with receipts & diagrams, should the need arise again. Good luck! Hope this info. was helpful.
