JVM1490B - Instructions

My door handle broke off right where the screw attaches to the door, leaving the small cylindrical portion of plastic still attached to the screw. Taking the door apart took a little while because the door handle screws are not easily accessible. It's not hard (with the help of the diagram), just time consuming. The only difficult part was getting the screw out since the plastic was still attached. I had to push the plastic in really hard with one hand with needle nose pliers and unscrew with the other hand.

The spacesaver is mounted over the stovetop. I removed the oven, then removed all the screws from the cover. Removed the cover and located the TCO and removed the wiring and the TCO. Ordered the part VIA internet and replaced it . It helps a little that I was Radar tec. and taught Electronics for 10 years and repaired lots of Microwaves. However anyone could do it just watch what you remove and replace in reverse order.

Had to remove outer cover (special screws involved). Found the correct part at PartSelect.Com and it arrived 3 days later as promissed.

This oven has diffcult electrical connections at switch to get disconnected. I found it easier with the sw loose and in hand so that the connectors can be released with a small screwdriver.

One has to this in order to test the part wirh an ohm meter. I found the sw did not close but remained open and thus caused the oven not to function.

Removing interconnect switch is tricky but not difficult.

Outer cover replacement is not as easy as it should be, especially the sides.

All is well and working.

Microwaves are simple devices if you are know how to read and understand schemetic diagrams.

Replaced

This is the second time replacing this fuse, last time was exactly one year ago. The first time I replaced it, I removed the oven from the wall & disassembled a number of things to reach the culprit. This time I left the oven mounted & was able to access the 2 grille mounting screws on the top of the grille & remove it. Next comes the black plastic air deflector held by two screws & is mounted in front & on the right, it is shown on the parts list just above part #1434. After removing it, remove the two silver cover screws in the front, this cover also doesn't have a part # but is shown to the right of part #1410. At this point you can lift this cover enough to access the fuse which is on the left & held in place by one tiny screw through the clamp at the top, (careful not to drop it when removing). PS: Don't forget to cut the power to the microwave before starting!

This was the second time I've had to open up the microwave. 1st time display would blank out but system would continue to operate. Found solder connections on board to LED display were defective. Resoldered and unit was fine. This time I found the connection to the oven cavity temp cut-off was bad, plastic connection cover melted. When unit operated bottom lead and wire would heat up. Couldn't measure a Discernable distance so either wire or connector connection surface was not sufficient to carry the current. 1st replaced sensor still wire heated up. Replaced connector and there was no sign how heat from resistances.

One small Phillips screwdriver and one fuse puller (I used cord). Unplug unit. Remove the two screws on the vent face plate. Remove the one screw on the panel assembly. Gently let hang. Pull the fuse located on the upper left wall. Replace fuse. Reassemble.

the main issue I had is the appliance manual stating that the bulb should be "unscrewed". when I first read the manual, before I received the bulb on delivery, I tried "unscrewing" the bulb, which actually is a PLUG IN bulb. small wonder that it didn't come out! luckily I didn't break the connections off in the socket!

the online instructions were ideal - just unscrewed the right-hand screw (the only screw) and replaced the bulb by inserting gently but firmly)...getting the old bulb out was a pain, b/c it shattered in my grasp (with little bits of glass all over the stove!), but that has nothing to do with the purchase and installation from this site - all a very good experience

Finnaly found exploded view of door, but had to guess how to remove snap in escution that covered the screws. Broken end of old handel piece spins with screw, so I am waiting for help to hold the front end, so I can remove the screw from the other side. Repair has yet to be completed!

Watched a couple of repair videos on Youtube by searching for the model number. Found out what to do in order not to get shocked by the powerful capacitor.
Ordered the two switches (To be sure, I could have ordered a third switch as suggested in the videos.)
Bought a tamper-proof star bit to get the cover off. Followed the directions to replace the switches. - I broke the harness and had to use some super glue, but it's all good. I should have removed the harness instead of trying to get a switch out while it was still in place.
It's all back together, and the wife is happy!!

Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

Remove the bottom of the microwave and remove/replace table motor.

The repair was very simple. I removed the broken grille and replaced it with the new one using only a screw driver . The procedure took less than five min. I was very pleased with the price of the new grille, which was less than the you know who, and how fast it took the part to reach my home. You get an a+ from me.
