20 Most Recent GE JES1142SJ Microwave Oven Questions & Answers

most times you have to take the outer case off (the stainless steel part) and then you can see all the wires circuitry etc. thats how you get to the light bulb. make sure you unplug the microwave first and do not touch where it says electric shock hazard it will shock you even if not plugged in

I would remove the outter shell and check the glass fuse inside next to the power converter.

It seems likely that the cyclotron has failed. If it is under warrantee then I suggest you return it to the place you bought it from to get it repaired. If it is out of warrantee, then you need to decide if the cost of repair is worth it, or whether you just buy another one.

If the timer counts down and nothing else happens, the secondary interlock switch is bad. This switch completes the cook circuit and this is why it doesn't run. You need an ohm meter to diagnose and find the right switch. Switch failure is caused by opening the door when it is in cook mode. Push the stop button first before opening the door and this failure will cease to occur. BE CAREFUL !!

follow this test and fix it. God bless you

1. Inspect the power cordUnplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
2. Bad door switchIf your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
3. Blown fusesTo determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
4. Bad fan motorLocate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

Call Lowe's to see if the warranty has run out. If still good, take it back. If not, call the manufacturer of the unit and see what the problem is. Sounds like the door support or hinge has weakened and the unit will not operate with the door slightly ajar. Unplug the unit for safety's sake until you find out what is wrong.

Try unplugging unit for 5 minutes then plug in and clear cancel. Re-set clock and tryto program. If this does not work, call service tech. A quilified tech will open up & test touch panel and control board.
