GE XL 1400 Spacesaver is not heating things up AGAIN!

My GE XL 1400 Spacesaver is not heating things up again. Same behavior as last time, but this time, ohm testing the magnetron did not see anything wrong with it. (See my post (name sclieu) 2 years ago about similar problem with the same microwave: http://www.fixya.com/support/t336131-ge_spacesaver_over_range_microwave_oven)


I am not sure if the HV Capacitor is bad. It has 3 prongs, not 2. Is there a way I can test to see if it's good or not? If I can't test the HV capacitor via ohm testing it, what is a safe way to test it during load? Could it be the damn magnetron again???

It's what, about 7or 8 years old? I'd buy a new one on sale. Probably not worth messing with just to squeeze out another year or two. You can pull out the Capacitor and take it to any electronics appliance repair place and have it checked for little or nothing, but if it's bad and you order a new one you have no microwave for a while. IF that's the ONLY thing wrong you're back in business.

SOURCE: spacesaver micro not heating

I have a spacesaver profile and after 4 1/2 years the magnatron went out. magnatron has a 5 year warranty so it was replace,But I had to pay for labor. 1 1/2 later it went out again. haven't replaced it yet. had a friend buy the same one at around the same time and the exact thing happened to them. I'm trying to find out if this a recall or if GE will stand behind there product. lets face it the time a microwave gets used at minutes at a time it really isn't much

SOURCE: GE Spacesaver over the range microwave oven

GE Microwave ovens, and Microwave Ovens produced by GE but released under different brand names, have had several power problems for the past 20 years. Because it is so easy to sell parts and charge outrageous rates for repair GE never corrected the problems. They just continued it in the next model. They found that you would most likely purchase a new unit rather than paying $75. for a service charge, and $150. for labor plus parts (if out of warranty period).
Most failures were cold solder connections on the power relay board. These would come completely dis-connected after arcing and burning away the solder. Could be 1 month, could be years, but they knew it would happen. This power relay board feeds 120volts to the LV (low voltage) side of the HV (high voltage) Transformer. No High Voltage,,No cook. Everything seems to run normal, but if you listen carefully you will not hear the low tone from the HV Transformer. Over my thirty years in the business I have re-soldered rather than replace so many I couldn't count.
Next to that, a defective Magnetron.

SOURCE: What size are t top mounting screws on the GE JVM1350 spacesave

You may be looking for the philips flat head 1/4 x 28 tpi (threads per inch) threaded bolt that is about 4" long. The tip of the bolt does not have threads, which aids in locating the threaded hole in the top of the microwave:

General Electric's part number for their OTR microwave cabinet mounting screw is WB01X10180 (or AP3205964 or 942461 as listed on some repair parts sites).

A set of three is GE's p/n WB01X10125 (or AP3185225 or 910236 as listed on some repair parts sites).

This flathead screw is used on most Advantium Speedcook microwave ovens such as the SCA2001BSS03 or SCA2000FWW03 or SCA2001KSS03.

Here's a picture of three screws:

SOURCE: Wires to magnetron

It matters!

The wire from the high voltage transformer high voltage tap goes only to one side of the high voltage capacitor. No other wire is connected to that terminal of the high voltage capacitor.

The other side of the high voltage capacitor connects to the anode (A) of the high voltage diode and to the "FA" terminal of the magnetron.

The cathode (K) of the high voltage diode is connected to chassis ground.

The pair of wires connected to the secondary (thinner) winding of the high voltage transformer are the filament wires and are connected to the "F" and "FA" terminals of the magnetron.

427ca4f.jpg

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

It has the overall wiring diagram and schematic.

SOURCE: My spacesaver dated September of 2004 shuts off

I solved the problem by buying a new microwave and it was not a GE. I feel that GE should have had a recall on this problem, since it seemed to be a major problem in their system. I will never buy another GE product.

Have ge profile spacesaver xl sensor. will not heat strange buzzing sound and burning smell. clock, light, vent still work


This is most likely a defective magnetron, especially with the burning smell. There are two other parts that can be a problem, the high voltage capacitor and diode, all three work together to heat food. If the magnetron is the culprit, probably cheaper to replace the microwave oven.

Light's on, plate rotates, no heat


When the microwave works properly but just doesn't heat, then the magnetron is bad and will need to be replaced. You can get the part and the diagram at partselect . com or repairclinic . com

Ge spacesaver 1400 does not heat


The most common fault with not heating is the high voltage fuse. I advise to either take it to a authorised repair agent to prevent shock or injury as many components still hold a large charge even after being switched off. Otherwise reply to this post and I will talk you through how to repair.Good Luck.

GE Spacesaver Microwave no longer heats JVM3670SF02


I would bet that either the first time or this time it is/was the magnetron tube, which has a 10 year warranty on the part, you pay for labor. Check and see what they did the last time, but they did have some trouble with the mags in these microwaves. If it was the mag, I'm not sure what area you are from, but $200 is a little high just for labor.

Its a free country Bage, but microwave energy is extremely dangerous! Repairs are not feasible unless performed by factory personnel under warrantry, and certified. I suggest you contact the manufacturer about the problem.

GE XL 1800 quit heating


I don't like to pass on your problem but it sounds very much like either the high voltage supply ot the magnetron has bit the dust.
Either one would make the repair marginal at best.

This is apparently not a very good unit, many microwaves jsut kind of fade away as their magnetron emissions decay.

This one seems to have a bad rep. look at this link:

Sorry, have owned a lemon or two myself.

Your magnetron, HV diode, Capacitor, or control board maybe bad most of these components run with high voltage and difficult to test without the proper equipment

GE Spacesaver doesn't heat


if you are as lucky as i was...i have a ge spacesaver model jvm130...same problem. first unplug unit and check fuse on the "power control module". if fuse is ok...unscrew the screws holding the "power control module" in place...carefully tilt module and see if a solder joint needs to be re-soldered. my problem was the solder joint under the front plug (5 large wire plug). you may have to unplug the three connectors to the board to get access to bottom. this is the second time i had to re-solder...last one was several years ago though. best of luck tennisrme
