    I'm having the same problem and I plan on replacing the magnetron once GE delivers it. Does anyone know where I can find instructions on the web for how to replace it?

When a magnetron goes bad, it has to be replaced. A magnetron cannot be repaired.

The parts and labor warranty for most brands is one year, and the magnetron warranty is usually about 5 years.

If it fails after the first year, you will have to pay for the labor for the home call and replacement of the magnetron, which often runs about $125-165, depending on your market.

They should not charge you the part cost of the magnetron.

HVM1750 won't heat


The magnatron is likely to be the problem... though I have seen the fuses go , they usually follow the magnatron.
If your unit is under 5 years old , the Mag is covered under warranty and all you need to do is contact GE at
gechsconsumerrelations@ge.com

with the serial number of your unit and they will send you the replacement magnetron imediately and free of charge.

You are responsable to have the part installed , but there are videos on Utube that will walk you thru it no problem.

Tip

Microwave Oven will not heat.


When your microwave oven has power, the fan runs, carousel turns, light comes on but the unit does not heat up you have a bad high voltage diode, bad filter capacitor or a bad magnatron in that order. The diode and capacitor do not cost very much. You can get them at www.mcmelectroncs.com or www.repairclinic.com . Replacement would mean removing the unit from under the counter (if not a tabletop unit) and removing the case. Locate the diode and capacitor. They should be near the power section behind the transformer and display. The diode is attached to the chassis on one side with a screw and on the other end with a spade lug to one side of the filter capacitor. The diode is brown and has an arrow on the side. The filter capacitor is a large oval silver can with two spade lug connections on one end. After replacing both parts if the unit will not heat you would need a new magnatron. The part is fairly expensive, but depending on the cost of your unit, it may pay to replace it. You should be able to get the magnatron at www.repairclinic.com . The magnatron replacement is not difficult. About four screws and several wires on spade lugs. Just be concientious or mark everything for correct reassembly. Also make sure the part is correctly installed and all seals are in place. You do not want microwave energy to leak out.

Microwave makes a loud roaring sound when start is pressed to cook something. The turntable turns and lights go on, but sound is horendous. We quickly stop it fearing it might be melting down.


Most likely it is the magnatron has gone bad, this or the fan for the magnatron. If your handy you can dissasemble the unit and look for a damaged fan, if none found then the magnatron is most likely bad.

Microwave light comes on and turntable revolves when food is put in, but it doesn't heat food up. Food remains cold, can you help? thanks Dee


9 times out of ten it is the magnatron that has gone bad, that is the device that creates the microwaves for heating the food. Check inside the cabinet for fuses and if none found or blown then it is the magnatron. These are available widespread but most cost about as much as a new oven, so do a google search on your make and model of microwave and search for a magnatron for that unit. This will bring up parts suppliers and their prices and you can decide if it is worth fixing or replacing

Power works, everything seems normal but no heat


microwave ovens do not produce heat, they produce microwaves. the heat comes from whatever is excited by the microwaves. In your case i would bet that the magnatron (microwave tube) has become defective. If this oven is less than 5 years old, the magnatron may be under warranty. depending on the model it may be repaired at no cost to you. In the case of Kenmore (Sears) you would take the oven to their customer service dept and they will send it in for you for evauation. they will charge you $50.00 US this amount will be applied to the repair if you choose to have it fixed. If the Magnatron is bad and is under warranty, they will fix it, and return it to you along with a refund of you $50.00.

Everything else seems to work fine but when I take


Magnatron has failed, possible internal fuse to the Magnatron,or the Magnatron itself has gone bad.
Both are replaceable, but the microwave will have to be taken down to gain access to these parts to be serviced.
Now, depending on the age of the unit, it may not be wise to invest the cost for this repair, unless, is it still under the manufactures 1 year warranty or did you purchase an extended service contract on this unit?
Good Luck !

GE spacemaker not heating


the magnatron has gone bad and maybe still under a warranty need to check with ge.if it is not then in most cases it is cheaper to go buy another microwave than to have it replaced.

GE Spacemaker XL1400 Microwave works but does not heat. From the research I have done it sounds like the Magnatron has gone up.


If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

NOTE: There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

THE MICROWAVE DOESN'T HEAT UP?


Is the unit under warranty? If not, you can try to remove the cover and see if there is a blown fuse in the section that powers the Magnetron. How old is the unit? Typically, no heating of food, indicates a bad Magnetron (tube).

Good Luck,

Food want get hot


Magnatron is the problem you need to replace it. I believe that this is still under warranty, so you can get a replacement free of charge.
