Moisture coming from GE Spacemaker stovetop microwave

After about 5 min of cooking with high moisture item (potato, water, etc)water runs down the back wall from behind micro. Repairman says nothing wrong - Tech Service says normal, turn of exhaust fan. Micro under warranty but no help coming. My thought - bad design - has separate cooling fan but cooling air no longer circulate thru micro cavity on this model - air comes in and goes out on component (touch pad) side only. HELP! Suggestion on how to proceed?

SOURCE: New microwave; loud fan when heating items

Update: I took it back. After speaking to GE, they said that's just how it is, there is no way to silence or quiet it. I took it back and bought an LG. I love it!

sounds to me like the magnatron has shorted out. i don't know of a way to test them unless you have some high dollar equipment. a continuity test prob wont tell you anything. what reading did you get on the cap when you tested it?

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

If it's still out, the problem may be on the control panel, which we regularly repair nationwide for $39.95 postpaid.

SOURCE: my microwave doesnt work

The radiation module built into the microwave has burnt out. The way a microwave works is that the radiation module produces radio waves that make the molecules in your food speed up, and the kinetic energy in the food makes it warm. The sound you hear is a fan cooling off the module and the light is just so you can check the food. Because of the nature of the module, it cannot be replaced and the entire machince needs to be replaced.

While baking a sweet potato, the potato exploded and caught on fire. The microwave no longer works.a fire bro


I haven't heard of such a thing. You must have cooked it until there was no moisture left in the potato. That would also account for the failure of the oven. It would be the same as no load in the oven.
A thermal protect part is your current problem.

Shorted touch pad


That can be remedied by either a replacement keypad or control panel frame assembly, or by getting rid of any moisture or grease on the control circuit board.
Please post a new help request here on FixYa and include the full model number from the tag in the cooking cavity or elsewhere on the microwave, such as the door frame, controller frame, etc. and detailed symptoms and when they occur.

Microwave stops working when heating food


Foods that are low in density or low in moisture (such as bacon and popcorn, respectively) can cause the magnetron to overheat.

That's because there is not enough of either mass or moisture to absorb enough of the microwave energy put out by the oven.

The excess energy then reflects back to the magnetron and causes a standing wave (like a poorly tuned transmitter antenna) and causes the magnetron to overload and overheat.

When the mag gets too hot, it trips the magnetron thermostat, a protective device which rests when it cools.

If this overheating is a persistent problem, a stopgap is to put about 1/3 to 1/2 a cup of water in a microwave-safe container (a Pyrex measuring cup is ideal) in a REAR CORNER of the microwave whenever you cook such items. This will help absorb excess energy, but you may have to increase cooking time just a little.

And of course I always suggest that food items be placed off-center in the microwave, NOT in the center of the turntable, otherwise the food is not exposed evenly enough to the microwave energy and will not heat as efficiently as it could.

(Placing it in the center is sort of like stirring paint by twirling a stick in the center instead of pulling it around in a circle in the paint can).

Such inefficient heating wastes the energy at best, and at worst it puts a strain on the magnetron.

If a magnetron is repeatedly subjected to such stress, it will prematurely fail. It will also draw excessive current, which can strain the high-voltage transformer.

That in turn will often lead to the oven's drawing excessive current, resulting in a hot cord and plug, and the fuse will blow - hopefully before the transformer or magnetron does!

An overheating magnetron can be due to:

  • operating oven without cover(s) in place
  • wrong magnetron installed in oven
  • an old or otherwise failing magnetron
  • cracked magnetron magnet
  • improper power line voltage (should be 110-125VAC)
  • foods low in moisture (popcorn & bacon, e.g. - add 1/2 cup of water in rear oven)
  • failed or inoperable cooling fan or hood vent exhaust fan
  • deteriorating foam weatherstripping seals in air ducts or on outside cover
  • blocked air vents (dust, animal nest debris, insufficient free air space behind & around oven, etc.)
  • clogged or greasy charcoal filter or grease filter
  • blocked duct in hood vent exhaust

We have a GE Spacemaker XL 1800 Microwave. There is dirt and moisture that has collected between the inside and outside glass. How can you clean this?


HELLO.

This is the solution to the cleaning issue.

1. Wipe the microwave inside and out with a soft cloth dampened with a warm, mild detergent solution. Rinse with a soft cloth dampened with plain water. Dry with a soft, dry cloth.

2. Put 2 cups of water into a 4-cup measuring cup. Place the measuring cup in the microwave, then heat on high for 5 minutes to loosen food particles that are stuck to the inside walls. Leave the measuring cup inside the microwave for 1 to 2 minutes, then remove and wipe the interior as in Step 2.

3. Remove the glass turntable and wash it in the sink with mild detergent or in the dishwasher. Handle carefully, as the turntable is breakable.

Thanks.

Shuts down on potato button only


Not much info to go on here. Are you putting in the number of potatoes vs.the cook time? Most microwave potato functions would not read "5 minutes." It would be read as a request to cook 500 hundred potatoes.

yes, at the back of the microwave there are 4 or 6 screws, take them out and then pull the cover follow the cable( the one you connect to the outlet) going to the inside of the microwave inside you will see the fuse change it with the same size, it is a slow burn fuse

GE Microwave won't heat or cook - one year old


More than likely the magnetron has failed. This could be for a number of reason. Do you use your microwave to heat wheat packs or warm plates? If so, you may have dried the magnetron out (they use the moisture in whatever you're cooking to heat it, and plates/wheat bags have no moisture).

I'd say a trip to your local Microwave repairer could be in order. It could also be the High Voltage Fuse which has failed. Either way a repairer will be able to tell you!

Actually, you should always use the hood vent exhaust fan when you're cooking on the stovetop, but I don't think that caused this problem, although it's possible.

Instead I would most strongly suspect a shorted high voltage rectifier diode, which is a pretty easy fix.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

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.

d:%5cele%5crepair%5cmicrowave%5cge_hotpoint%5cmini_manual_behind_grille_small.jpgdee77f7.jpg

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

(if it's not shorted or burned, it's probably okay)

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

I always recommend that folks use the vent / hood fan anytime they're cooking with the stove.

Was it on at the time?

If not, moisture can certainly get into the works and cause problems or damage. If it dries out, it's fine but if not, it could cause damage.
