Re: My Microwave does not heat up or cook...

We have a 1000W microwave oven by emerson. MW8119SB. I fixed popcorn in it and started to fix another bag in it. Cannot get the clock to work and I can only get 99 seconds to come up. Heats good. What can I do to get the clock to work and to get the minutes to work correctly.

Our MW8111SB just started to overheat. The vents on the side and bottom are not obstructed, but once the microwave is turned on it begins to get excessively hot.

If it's new and under warranty, I'd contact Emerson. They should stand behind it and support you so you can be sure you're using it right.

Get help using your appliance 1-800-898-9020 ; Get help locating a servicer or parts 1-800-695-0098.

If it's not under warranty and you or a friend want to work on it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, linked here on Fixya:

Why doesnt my microwave heat up emerson 1000watt

If it is not heating properly, then the klystron is probably bad. The klystron creates the energy to cook the food.

My mother just bought an Emerson MW8119 Microwave and can't figure out how to only set say 15 seconds cook time. Is it possible?

Hi! I just purchased the same microwave, and came online to find the solution. I was then able to find the correct answer to this problem. On this model, Emerson does not put a "time cook" button for odd cook times such as 15 seconds. Instead, they have you push the "Power Button" prior to setting the cook time.

If you want to cook on full power, press the power button once, and then enter your cooking time and press start. If you want to cook on 50% power or 30% power or something like that, push the "Power Button" several times until the appropriate power level is displayed, then enter the cook time and press start.

The reason that it starts up right away when *********** pushes the 1 button is because Emerson has the quick cooking feature for 1 minute through 6 minutes. You only have to push the number once to get the 1 minute cook time or anywhere through 6 minutes respectively.

Hope this helps!

Microwave caught on fire.

I agree! That is an extreme hazard. Possibly due to over voltage of the power supply or faulty relay systems. Emerson is usually a cheaper brand anyhow. I would get the money back instead of exchange.

Hi I have an Emerson microwave oven MW8998B. The turn table will not rotate while cooking. The smaller bags of popcorn just burn the bag. Does this need a repairman or can I fix it myself. Also, I am able...

Hi, I had the same problem with my Emerson microwave. As I rent out the house, and the turntable stopped working while I was away, my rental agent bought another Emerson microwave. On my return I tried using the new (brown) plastic turntable on the old microwave, and found it worked perfectly. Maybe it would be possible for you to order a replacement turntable part. Hope this helps. Good luck, Rosalind

My microwave quit working

You have obviously damaged the circuitry. Service is expensive. Unless the unit is under warrantry my advice is to replace the oven. The newer ovens are very reasonable and have great features. Check Home Depot.
