Question about Microwave Ovens

1 Answer

It completely shuts off after 3 or 5 seconds of operation, it happens on all cooking times and power levels. no matter if the vent fan or light is on or off. The failure is intermittent and started like a year ago but now is more frequent and annoying since time and date have to be set every time GE JVM1650BH01 SpaceMaker

Sadly, we hear of this over and over.

This is usually due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

GE had a campaign (but not a recall, mind you!) covering several models.

Details are in their bulletin at http://207.234.249.73/mwd/ge_mw_mag_kit_bulletin.pdf

Even if your model is not on the list, the same problem can occur, requiring a kit. I just think the difference is that GE has stopped paying for the repairs.

The parts kit (that GE used to pay for) is part # WB27X10489 and is shown here: http://207.234.249.73/mwd/wb27x10489_ge_mag_stir_kit.jpg

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

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

Our microwave, a (built in cabinet with venting), will tend to shut itself down if we cook something longer than, say, 8 minutes straight. No power, lights on panel out. Then a few minutes later i


Not enough venting. Imagine putting your hair dryer on full and putting it that cabinet. Would your venting keep it cool? Your microwave oven uses about the same current

Panasonic Microwave suddenly won't cook.


Your microwave is detecting an internal shot and shutting down, Most likely due to a faulty Magnetron which is not a part that is worth replacing due to the cost of the part and the decrease in cost of new microwaves.

Does the exhaunst fan turn on automatically when we cook or warm food items in our Samsung Microwave -- SMH 9187W?


Some interesting reading on page 8 of the owner's manual:

"Boilovers cause smoking and greasy spillovers that may ignite and spread if the vent fan is operating.To minimize automatic fan operation, use adequate sized cookware and use high heat on surface units only when necessary."

And on page 20:

"If the temperature becomes too hot around the microwave oven, the fan in the vent hood will automatically turn on at the LEVEL 2 setting to cool the oven. The fan will automatically turn off when the oven has cooled down sufficiently. This is an automated process and cannot be turned off. The fan may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. The Vent Fan will only operate in 1~4 levels modes while the microwave is working."

"Using the Vent delay off button
1. Press the Delay Off button once to turn the fan off after 1 minute.
2. Press the Delay Off button twice to turn the fan off after 3 minutes.
3. Press the Delay Off button three times to turn the fan off after 5 minutes.
4. Press the Delay Off button fiour times to turn the fan off after 10 minutes.
5. Press the Delay Off button five times to turn the fan off after 30 minutes."

If for some reason you don't have your owner's manual, you can still download it free here.

I have Emerson Microwave #mw8999sv which has the Express Cook option- cooking 1 - 6 minutes. How do I cook for 1 minute 30 seconds, etc.? Thank you.


The owner's manual is here. On page 10 we find:

COOKING IN ONE STAGE
1. Press the POWER button; the Microwave and High
Cook indicators will light and “PL 10” will light in the
display.
2. Press the POWER button different times to set the
desired power; the display will show the percentage
you chose. If selecting power level 70%-10%, the
Low Cook indicator will light instead of the High
Cook indicator.
3. Press number keys to set the desired cooking time.
OPERATION(CONTINUED)
4. Press the START/+30SEC. button to start cooking;
the Microwave and one of the Cook indicators will
blink and the display will countdown the remaining
cooking time in minutes and seconds. It will beep
five times when cooking is completed.

Samsung MU3250W Shut down


It could have been steam or humidity.

If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

When in doubt feel for air flow through the vents.

Good luck.

1800 XL JVM1860BD - won't work


It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.
