JES1289S General Electric Microwave - Instructions

After looking up on the computer a schematic of the unit, all that was needed was removing four screws to remove the top and side cover which was one piece.
Next was removal of electrical connection to burned out lamp, then removing burned out lamp and installing the new lamp and reconnecting electrical connection.
Job was complete after reinstalling the cover.

Microwave now working with new lamp lighting when in use.

Door microswith was stuck on. This is caused, I discovered, by frequently stopping the oven, while running, by opening the door rather than using the stop button. Causes the switch to arc and eventually fail. This causes the safety microswitch to trip the breaker when door is opened. There are little nubs sticking up on the spade connectors. You must squeeze them down before you can remove them from the switch. The main door switch is the upper one, mounted at an angle. You have to remove the latch assembly to remove the switch. The problem was obvious once I got the switch out. This problem could also blow the fuse, but in my case the breaker tripped first. Use an ohmmeter to check switch and fuse. The door switch is normally open. The safety switch is normally CLOSED. Instructions inside were helpful and described this problem. So, avoid this repair by always stopping oven with stop button!

I happen to have a set of "security" screw driver tips which are required for this appliance - available for about $10 at Home Depot or Harbor Freight. Remove three security screws from back of housing, lift up and aft to remove the cover. The light is on the left in a "snap in" mounting so use a flat blade screw driver to push back the retainer and lift out the old bulb then disconnect the two "push on" wires and install the new light. Total time about 10 minutes. The only issue is the requirement for a security driver set.

removed 3 screws to take off outer housing ( did not have proper screw driver but was able to remove with pliers). used flat head screw driver to pry light socket w/bulb off of snap-in mounting & unplugged socket wire attachments. plugged in & reattached new part.

Removed the three screws holding the cover on. then rmoved the two wires from the capacitor. Removed the screw holding the end of the zener diode to the chassis. Removed the diode from the capacitor. installed the new capacitor and replaced the blown fuse then reversed the removal process.

Went on line and saw the Video - very simple to follow - very easy to remove and install the new switch -- went like a breeze!

removed 3 screws from back took cover off pulled out socket pulled off terminal replaced bulb then reverse order back together. all while unplugged.

Fast & easy. I was able to determine that this foot would work from the descriptions on online!! Thanks

they had everything I needed, friendly service, fast shipping, no problems

Remove the door and order the part. With in a day the part was at my front door. 30 minutes later was using applicance. Superb service from this company!!!!!!!!!

Replacing the light bulb is easy and takes no more than 15-30 minutes. The light bulb is located behind the grill on the right hand side of the microwave as you face the microwave. To get to the bulb you have to remove the outside cover. On mine there were three screws that had a special head and required a special tool. That was a surprise! To work around that, since I did not have the tool, I used a pair of needle nose pliers to grip and turn the screw head. They came out easily. I replaced them with the same size Phillips head sheet metal screw when I put the cover back on.
1. Remove the screws that secure outside cover and take the cover off.
2. Locate the light bulb and unplug the power wire. It is a two prong plug that pulls off with little effort.
3. Remove the old light bulb. It is held in place by a plastic tab. Push the tab toward the outside of the base plate with a small screw drive or your finger and lift the base plate. The bulb will come out with the base.
4. Install the new bulb. Align the holes in the base of the new bulb with the tabs on the socket and put the bulb in place, ensuring the tab secures the bulb base in place.
5. Reconnect the power wire to the bulb.
6. Reinstall the outside cover.
7. The light should come on when you open the microwave door.

Simply remove the cover after unplugging the Microwave. The light is attached to a bracket and unplugs from the electrical system and then pops out. Replace with the new bulb and bracket, reattach the electrical connection and replace the cover. Less than 15 minutes. Just need a special star screwdriver bit with a hole in the middle to remove and replace the screws holding the cover to the frame.

It took two people because we have built-in unit. The power plug was in cabinet above.First had to remove front frame in cabinet with Phillips screwdriver. Removed microwave from cabinet box (be sure to wear gloves, edges are very sharp). Then unscrew outer shell of microwave - easy process. Easy task to remove bulb/socket piece. We ordered part from Part Select - friendly service and the price is the best. Even with minimal shipping costs, the local prices were more than double. Important, it is a bulb and socket part.

Our microwave oven stopped working one day when the door was closed. The clock stopped showing, the light didn't come on when the door was opened, and the microwave couldn't be started. It acted as if it lost power. So, we did the usual things such as check the plug and the circuit; these were fine. I then removed the cover (need special bits called "Security Bits" which you can buy from Home Depot for $8.00). After removing the cover, be sure to discharge the capacitor (do a Google search to learn how to do this; fortunately, this microwave has a resistive circuit to ground to discharge the capacitor after about 30 minutes of being unplugged). After I discharged the capacitor, I checked the fuse and it was blown. So, I went to the store to buy a new fuse. When I replaced the fuse, and plugged the unit back into an outlet, the circuit blew as soon as I opened the door. This made me realize the faulty components were the "interlock" switches. These are relays (an electric switch) that cause the microwave to shut off when the door is opened and the inside lamp to illuminate when the door is opened. There are two "primary" switches and a "monitor" switch. I checked both primary switches for continuity (do a google switch for "checking interlock switch"). The one interlock switch was bad, meaning, it wasn't opening when it was suppose to. I ordered a replacement and also replaced the Monitor switch too (not sure why, I guess because it was only $6 to buy). After replacing the bad primary interlock switch, I put it all back together and we're working now!

Remove bezel (4 Phillips sheet metal screws). Pull out unit and unplug from wall. Remove three sided steel cover (T15 or T20 safty bit required). Unclip double wire plug from base of lamp. Unclip and pull up on the lamp/bracket - discard. Push down new lamp/bracket, plug in wire socket to base of lamp/bracket. Replace steel cover and 4 'safety headed screws'. Lift unit, replug into wall socket. Insert into wall. Replace bezel and 4 Phillips sheet metal screws. Without the special "safety screw bit", this repair is impossible.
