I just bought the emerson mw8999sb. I opened the box, read the manual, plugged the guy in. The buttons all work, clock set, timer. But when I hit power and then set the time.... it will not start cooking. Why? What do I do? The light stays on when the door is shut... is that normal? Please help!

Sounds like a classic bad door switch or switch holder. If you or a friend decide to work on it, we have *critical* safety info, info on door switch testing and replacement, and oven disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383

SOURCE: Shuts off, must reset clock

I had this problem also, but what happened with mine is that it popped about 1/2 the bag and then the light popped inside the microwave and it shut down completely. My husband went out to see if the circuit breaker popped, it didn't, but he switched it anyway and the microwave came back on. So he put the micro on a power surge protector, and we tried again, but this time we used the minute timer and it just popped about 1/2 the bag and then blew. The surge protector still was working and so was the outlet, but the microwave was blown. About a 1/2 hour later, I looked in to see the micro and the clock had come back on. We just purchased this at Home Depot this past weekend, should we take it back and get another one? or is it our electical outlet?

SOURCE: Hi. I pressed the 'quickstart'

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. Then let us know if the hard reset does not fix it.

It may be a problem with a door switch or door switch mount.

SOURCE: JVM1190 wont cook

You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

SOURCE: Microwave Oven Does Not Start Cooking

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

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.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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:.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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 & testing.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I have an Emerson 900W Microwave MW8999SB and it will randomly assign DEF1 and the rest of the keypad is difficult or not functioning. None of the quick buttons work, and only the 30-second button works....

Pressing the Clear/Pause button works. Sometimes. Most of the time, about a microsecond after pressing Clear/Pause, it goes right back to def1. Most of the time, pressing ANY button doesn't work. Usually takes me 10 to 20 tries to get anything to work. My microwave is about 3 months old. I will never buy Emerson again.

Emerson microwave not working 900 watts

The Emerson MW8999SB 0.9 cu. ft. 900 watt Microwave Oven is relatively compact, and certainly inexpensive, but doesn't skimp on functionality. We were surprised at all the options you get with this little microwave. It's only 20 inches wide, 11.3 inches high and 16.1 inches deep yet. The interior can still accommodate a regular size dinner plate or small (10-inch-square or round) casserole. Plus, there are 10 power levels, eight one-touch function buttons, six Express Cook settings, timed and automatic defrost options, and a rotating glass turntable to circulate the food for more even cooking.

We were very pleased with the performance of the Emerson MW8999SB. It did a fine job heating water for tea, cooking a couple of baked potatoes, reheating leftovers and steaming fresh vegetables. Even the automatic defrost proved surprisingly efficient, letting you enter the weight of the item(s) to be defrosted (4-100 ounces) for easy operation. Chicken breasts were almost fully defrosted after one cycle. We needed to stop and separate the food pieces to finish the defrost cycle.

The unit is styled mainly in black but has stainless steel trim around the door and control panel. The smooth touchpad control panel is attractive and easy to wipe clean. We loved the one-touch Express Cook buttons, which let you activate the unit at 100 percent power for 1-6 minutes, by pressing the corresponding number pad. We also appreciated extra touches such as the Start/+30 sec. button, which can be used to start the oven or add an extra 30 seconds each time it is depressed.

It's hard to go wrong when the functions are so simple. The only tricky part was identifying certain codes used on the display screen. When changing the power level, for instance, PL10 is displayed on the screen. Pressing the button additional times lets you toggle through the different levels. Likewise, the Auto Cook settings may need to be pressed multiple times to obtain the correct weight or portion for the food being cooked.

We were amazed that a machine costing so little also offered two-stage cooking, which lets you start cooking (or defrosting) on one setting and finish on another. All in all, the Emerson MW8999SB is an excellent value.


Pros: Touchpad controls, eight one-touch function buttons, six Express Cook settings, two-stage coking option
Cons: Limited interior capacity can only accommodate dishes up to 10 inches, no sensor

I have the black/stainless steel m/v MV8999sb. Just today, when I used the any express cooking button, instead of cooking, it is acting like a kitchen timer. It is also flashing to icons on the top; one...

The two icons are normally present for any timed cooking in this microwave. If you are not getting the food to heat (since express cook is at 100% power), the magnetron, thepart that produces the microwaves, may be damaged. If your unit is out of warranty, it may be easier to replace it.

The part itself is fairly cheap: http://www.partstore.com/SearchResults.aspx?q=Magnetrons&cft=Microwaves+_gt_+Magentrons&cfilt=374&sort=salesrank&ctf=Parts&ctfn=Parts&ps=100&bf=731&bfn=Emerson . However, you need to avoid damaging the seals to avoid having the radiation leak. (It makes the microwave inefficient and can be dangerous to people and pets nearby.) Additional parts for microwaves are also available at partstore.com: http://www.partstore.com/Content/CategoryPages/Kitchen-Microwaves.aspx .

The manual for the MV8999sb is available here: http://kitchen.manualsonline.com/manuals/mfg/emerson/mw8999sb.html . Click the Get this Manual button. See page 13 of the PDF for the pictures appropriate to the Quick Cook option.

I hope this helps.

I have an emerson 900w microwave mw8999sb sn908003050mm. I have tried cooking in it and setting the timer at the same time to time something else that I am cooking. Can it be done with this type of...

The owner's manual is here, and it does not mention that as a feature.

One way to prove that is to press the "Kitchen Timer" pad while the oven is cooking and see if anything happens.

No modern microwave that we know of has this dual function, but it sounds interesting.

  1. Unplug the unit for a minute then plug unit in.
  2. Press the clock (clock/timer) button once.
  3. Using the keypad, input the time you wish to set.
  4. Press the clock (clock/timer) button once.
  5. Press the stop/clear button, Time should remain.
Hope this works, if not, let me know.

Please take the time to give this solution a fix ya rating.
