86130 - Instructions

tested all 3 of the door switche for continuity, the top switch was faulty, replaced it,for approx $4.00 and saved a $350 dollar microwave.

I unwired the overload and installed the new overoad. Plugged the starter in to the back of the compressor and wired it up. Now I'm trying to get the freezer filled up again!

Note: also had to replace turntable. Removed top cover using secure driver set. Placed microwave on it's front, using a soft towel. Removed edge screws from bottom plate (leaving 4 screws in center attached to heavy transformer). Separated bottom plate from body of microwave (leaving transformer wires still attached) exposing Synchronous motor. Removed two screws holding motor and electrical plug. Swapped new motor in its place. Re-attached bottom plate with its screws. Placed microwave onto it normal position. Re-attached top cover with its secure screws. Installed new turntable inside.

Removed micro bottom - 5 screws. One screw on the motor and a clip. Reversed the sequence, turned it on and watched it turn.

Remove the cardboard access cover at the bottom back of the fridge. On the left side, locate the run capacitor. Remove it by prying it loose from its socket, after first removing the wire hold down clamp. One wonders why the clamp is there, which makes it difficult to get the run capacitor out. Be careful not to disrupt in any way the copper refrigerant tubes. If you mess them up, you will have wasted your time and effort trying to repair the machine. I was lucky, since a failed run capacitor is the problem only about 12% of the time, based on what I’ve read. Hallelujah! It was the problem with my fridge.

Opened mailer and bag and place the drain plug into the drain. fit perfectly. In fact it is better than the one lost since the original needed a screwdriver or tool to remove the plug. This one has a flang or finger turner on it so that it can be removed. Also, does not interfere with items in bottom of freezer.

Remove 2 Philips Head screws on left side of microwave. Remove 3 Philips Head screws from bottom rear of microwave. Remove 4 security screws from back of microwave (holding the cover to frame). These are the security type tips that are like a Torx bit, but need to be hollow in middle to accommodate pin in center of screw. Then back plate of microwave with heavy transformer still attached slides up and away. The wires aren't long enough to allow it to rest flat on the bench, but weight is low so it's easy to hold it upright while removing the motor unit. Separate connector from motor (simple) Remove motor by unscrewing 1 phillips head screw and rotating counter-clockwise a tiny bit. Remove Motor. Reverse steps to re-assemble. Note that there are a series of tabs at the bottom of the back cover that fit into holes in the baseplate of microwave. It can be a little tricky to line them up with the weight of the transformer, but it's not too bad. Once lined up, it drops in nicely and all the various screw holes line up. The microwave is a bad cooker when the plate doesn't spin. This simple and inexpensive fix saved me from having to buy a whole new oven.

Removed the MW from the wall. Took the top screws off the air vent. Then removed the two screws holding on the display. I then moved the display to its side and it revealed the micro switches. I removed the plug in leads from the micro switch one at a time. I did this with all three micro switches only one at a time. I reinstalled everything and plugged it in. No more fans starting when the door is opened.

Removed outer cover

removed lower door switch

installed new switch

Wa La!

Turned the microwave on its side. (Recommend turning it on its top. i had to fish the wire connection back to the center after it dropped away from the motor.) There is a spot under the rotation motor where an access port was stamped in the tin but not cut out. Used the small side cutter to complete the cut where tin had been left between holes. I unplugged the wires, removed the old motor by removing one screw, and installed the new one by reusing the same screw. The motor must have a reduction gear inside the case. The motor coil tested good, about 128 ohms, but it acted like there was a stripped gear inside. I wasn't interested enough to try to open the motor and confirm.

Had to go to the garage and get a small sheet metal screw to close the new trap door.

The "new" motor had scratches on it, made me wonder if it was really new, but it works fine and will probably outlast me.

Ordered the Capacitor and the Thermostat Control. Parts were received in a matter of a few days, easy to install, but did not fix the problem. Had to call a repairman to fix the problem (compressor relay - this part not available to order for this model number with Parts Select). Will continue to use Parts Select in the future for other parts, but not happy that the actual part I needed was not available - had to use other methods.

tested cap. with ohm meter which showed a short. A new HV cap., a fuse and it is working fine again.

I looked up my problem on the internet and found a very helpful video. Microwave on video was different brand but the internals and methods were very much the same. The video made it simple and easy to fix. Found the replacement switch on the LG parts site and ordered. Two different switch types. One with red switch, the other green. Part was $7.28. Saved a bundle in service costs. Here is the repair video.

A little research told me the hum plus no cooling was either the compressor or the relay. I ordered the new relay and put it in but it didn't fix the problem. I ended up having to buy a new fridge, but it was worth the $30 gamble to see if I could fix it on the cheap and it saved me the money a service call would've cost. Pretty easy installation, just in a tight space on my model.

Take off cover then the bottom. Transformer is on the bottom plate and wires won't let it come all the way off, too many wires to pull off so will have to position the bottom plate so you can get to the motor. Remove 1 screw on motor and remove motor. Install new motor connect wires replace bottom plate, replace cover. All done (hope & pray it works ok) mine worked perfect. Hope this helps.
