20 Most Recent GE XL1800 1100 Watts Microwave Oven - Page 9 Questions & Answers


HI. Your symptoms are a strong indication Magnetron failure. This is the principal heating device, that is used to produce microwaves that , essentially, excite the water molecules in the food, thus, producing the heating effect. When this device fails, generally, the unit will run, but not heat. This device is very fragile, and can injure you if you are not qualified to handle this type of component. There is a High Voltage Capacitor, that is used to help provide the necessary current for optimal Magnetron operation. This capacitor must be discharged correctly. If not, you could risk serious injury, during the repair, if it is accidental touched.

The Magnetron is linked to a cut-off fuse. If the magnetron becomes unstable, this fuse will shut the device down. It is standard procedure to have this fuse test for continuity. If the fuse has blown, this will be the culprit. Replace the fuse. Now, if the fuse continues to show continuity, this will confirm that the Magnetron has failed. I would advise to inspect the Capacitor, and HV diode for visible burn marks, or swollen top(Cap).

Access can be ac hived to these parts by removing the outside cabinet screws. Once the screws are removed, the cover can be removed, as well. Once the cover is removed, the internal components will be exposed for testing, and visual inspections.

WARNING: IF YOU ARE NOT A QUALIFIED SERVICE TECH, THIS WILL NOT BE A NOVICE DO IT YOURSELF JOB. MICROWAVES ARE VERY DANGEROUS, AND CAN CAUSE SERIOUS INJURY. I RECOMMEND TO CALL FOR SERVICE, IF YOU ARE UNCOMFORTABLE WITH HANDLING THE CAPACITOR, OR MAGNETRON.

It is usually the magnetron tube that fails which then blows an inner-cabinet fuse. The world seems full of bad Asian made magnetrons that fail prematurely due to air infiltrated internal vacuums from leaking metal to glass seals. It will probably cost more in parts and labor to repair than a new unit. A well made magnetron should gradually lose output power over time (years), not just quit. Hope this helps!

Hello :

To locate the fuse, remove the outer cabinet of the unit, which is usually held in place with a few screws. Once the outer cabinet is removed, follow the power cord into the unit. It will take you to the fuse holder, where the fuse sits. The fuse holder is located two or three inches into the unit, and may be attached to a power board .


CAUTION: Your microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. We strongly suggest you seek the assistance of an appliance repair technician when conducting any microwave oven repair.

good luck .

Hello :

It could be bad door switch or loose door switch mount . There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

or it could be problem with the control panel .


good luck .

Voltage will be the same as your household and the appliance, and 99% of the time that's 110 if you're in the US.
What matters more are 2 specific shopping details; Wattage and base size (width)...The first detail is stamped/printed on the original bulb, and base width (not diameter) is easy to determine by laying the old bulb on a ruler.
Overall bulb size doesn't vary much, and is easy to match at the supplier.
Which was the other part of your question: Where to buy.

Most Walmarts carry a small selection of appliance bulbs, as does the local HomeDepot...You will need those 2 shopping details to zero-in on the replacement, then verify that the overall size of the glass is the same of smaller.
(A bit smaller is OK, provided the wattage and base-size are the same...but too wide or too tall, and you can't get the cover back on.)
Best Buy can order the bulbs for you if their service dept doesn't have it in stock, and Sears offers the same service.

When all else fails; Hit the Yellowpages under "appliance parts" for a local parts shop...The bulbs are for the most part fairly generic, and any decent parts shop will have a few in stock.

I gather that GE would replace the part under warranty but you need to pay labor? $200 to replace a magnetron seems way out of line just for labor.

The magnetron is the most likely part to cause your symptom. Capacitors and diodes usually fail by shorting, and cause the oven to make loud humming noises or blow the fuse. But the trouble might also be due to the control circuit board, either bad parts or solder connections.

Unless you have the proper tools and experience, trying to diagnose where the trouble is can be very hazardous. There are lethal voltages present with the cover off and the oven operating. You should leave the repair to a professional. An independent shop might be able to diagnose the problem and give you an estimate for a lower charge, and then you could decide whether to repair or replace.

Now this is not quite clear enough to give an accurate single answer.

Is it the fuse within the microwave or the general house supply fuse that blows?

If its the latter then an electrician needs to create a separate fuse line to reduce the overall load on the fuse, 15amps generally. Many houses have too many plugs being used at once on the same circuit TV, dishwasher, fridge/freezer, electric jug etc all drawing power. Big screen Tv's are the worst offenders.

If it is the fuse within the Mwave, then it needs attention,as a short has developed in the unit and needs to be corrected.

I will assume it is less likely to be this and punt for the first solution ( House fuse box overload)

Sometimes a random glitch will cause this, and a "hard reset" (cycling power) fixes it.

Other times, you may have a failing controller.

Hi,

On most Occasions, it is Magnetron. If you ON your Oven and hear an Humming noise, that usually confirms Magnetron Problem.

If the microwave functions normally while cooking everything else, but is only burning popcorn, there is no component problem that will cause this. You cannot adjust or replace any internal component to make it not burn popcorn. All power levels and program options are contolled by the consumer at the control panel. Refer to your owner;s manual for their recommendations.

If the oven is equipped with a popcorn feature button, it is programmed for a recommended power level and time. This is an ESTIMATED program feature. The manufacturers of both the oven and the popcorn will also give directions that tell you to turn the oven off when the popping slows to about a pop every 2 seconds. Failure to do so can result in burning.

If the microwave does not come with a popcorn feature button, the manufacturers of the popcorn have directions on the outside of the box that tell you what POWER LEVEL and TIME to set the oven on for the desired result. Again, the you still have to listen as the bag pops to ensure it does not burn.

In addition, on some microwave ovens, there is a feature that allows you to select the SIZE of the popcorn bag. Some popcorn manufacturers have smaller snack size bags that don't take as long to pop. You have to select the appropriate size to get the correct program option.

In any case, you never are to place popcorn in a microwave oven and walk away from it. All these program features are ESTIMATIONS based on manufacturers testing and recommendations for the best results. All microwave ovens are different and operate at different power levels. Your best judge is to listen as it pops.

I hope this helps you.

sounds like the transformer is shorted/burned,i would that you purchase a new one

GE XL1800 1100... | Answered on Dec 12, 2009


We have a sound clip here of what a microwave should sound like when the cooling fan and high voltage section are working.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)


http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)


You can find links to helpful exploded view diagrams and part ordering help here.

If you still need help, to allow us to help you effectively (at no charge), please post a NEW problem to FixYa, and please include your brand name and the full model number and date of manufacture from the tag in or on the unit, your exact symptoms, as well as the answers to these questions:

- When you try to microwave are the inside light, internal cooling fan and turntable all working?

- Is there any unusual noise or is it louder or quieter than normal?

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

- Did you ever spray cleaner on the controls?

- If it's an over the range type. do you always turn on the hood vent exhaust fan when you cook on the stove top?
