JVM1190BYC03 General Electric Microwave - Instructions

Removed upper face plate and fan cover with small cross point screw driver. Attached 24 inches of cord string loop to the driver end of the belt, lifted the belt off of the pulley, removed the belt from the fan, pulled the belt and cord string out. Attached the new belt to the cord and reversed the drill. Replaced the covers. It took me longer to write this note than it did to replace the belt.

I took instant pictures at each step to make sure I put the wires back correctly. Removed the front panel. Discharged the capacitor with a voltage meter. Removed parts in front of the magnetron. Removed and replaced the magnetron. Reassembled. Works find now. Small hands, a flashlight and a magnet (for dropped screws) would help. I did not need the pictures.

First, unplug microwave. Unscrew two screws at top of microwave, slide grill cover left and remove. This allows access to single screw holding control panel. Remove this screw and lift up control panel to remove. Secondary door switch is black switch at lowest position. The switch is held in place by a lever in back and very hard to get to. Remove the wires plugged into the switch, then remove two screws holding the plastic switch mount that holds all three switches. These screws use a "star" type screwdriver. Once the plastic mount is free, lift it up, right, and tip it slightly to find the lever that will release the black secondary door switch (the lowest switch)...release the broken switch, snap the new switch in its place. Replace the plastic mount by lifting and replacing back into position and replace the two "star" screws. Now, replace the wires onto the new switch, and test operation. Replace control panel, and top grill. It goes faster than it writes...getting the old switch out through that difficult to reach lever was the hardest part...still less than thirty minutes.

Because the microwave is old and the bulbs, I believe, had never been changed I carefully tried to unscrew the bulb. However, when I went to unscrew the bulbs the end of the bulb broke off and remained in the socket. I used a few different tools then remembered that sometimes a raw potatoe can be used to unscrew the remainder of the bulb, but to no avail. Finally had to unscrew the whole underside of the microwave to remove the broken bulb. May I suggest that you have the socket face away from the wall to screw in the bulb instead of the socket pointing toward the wall. You need to know yoga just to manuver the bulb into the socket.

every thing is working, but no hot

First, there are three door operated switches in this model. The monitor sw, the secondary sw (both of these are on the bottom in the same bracket) and the door sensing sw on top. The door sensing and secondary switches are both N.O. and have the same part number (probably why you show just two switches). The monitor sw is N.C. and it was not my problem. The secondary sw was bad on my oven but I had replaced the door sensing sw (which wasn't bad) on a previous order and kept the old one so I used it to make the repair. All three switches can be accessed without removing the oven by removing the discharge louver (remove two flat head screws on top and slide the louver to the left) then carefully remove the control panel (one screw on top and lift out). The switches are held in place by a plastic tongue that fits into the rear mounting hole on the switch. I used a common screw driver with a small tip to gently lift the tongue and slide the switch out with needle nose pliers. The new switch just snaps back in. The switch holder bracket looks like it would be easily broken so be gentle. I don't know what the symptoms would be if either of the other switches were bad so I would recommend buying all three and you would have them if one of the others failed in the future. The information I gave on the switches came from a schematic I found inside the control box. Hope this is helpful.

Microwave would not turn on. Lights and fan worked fine. Before the microwave stopped completely, it would turn the microware fan on even when door was open. I read the reviews and they were exactly the same issue that others were facing. Once I opened the front panel and got to the switches it was easy to figure out which switch was bad as it was the one that was soft (When clicking it). It was hard to take it out though (it seemed stuck). So, I used a plier to yank it out. I put in the new switch and everything worked just great! I would like to thank other comments that were left on the site to make my task much easier. Thank you (to the commenters on PartsSelect), you not only saved me money, but also ensured that I learn about the microwave more and give me the confidence that I could fix it.
