I have an Emerson microwave that recently became only a big kitchen timer for some unknown reason. The cook function will not work. I unplugged it a couple times, once for over an hour, thinking that it would auto-reset but it didn't. What happened? How can I fix it?

I googled Emerson electronics and came up with the following. I also came across some pages that customers of emerson products thought they were junk. You could also take the microwave to a electronic repair shop and get another opinion. You should be able to find them in the yellow pages. When my cd player stopped working I asked Best Buy folks who did their repair work and took it there for repairs.

I hate to say it but you will probably be better off just getting a new microwave :-( But the good news is that there are so many really inexpensive ones on the market now that will work for a long, long time and in the long run it would cost less to purchase a new one rather than wasting time trying to find out how to fix it or by paying repair money to have it checked out and fix it :-(

If you're really in a pinch and can't afford, say a $70.00 on sale at a Target or other stores for a new one, you can check your local Goodwill or Salvation Army stores for one that might be around $20.00 and they will let you plug it in there to test that it works. Good luck and let us know how it goes for you. Oh, and don't get the Emerson brand again ;-) LOL ;-)

Microwave ovens are something you need to be careful with. I had a GE built in microwave over my stove. What a real pain in the back that was to install! You might know it one week out of warranty the turn table stopped turning. Also the inside of the microwave door is all chipped! I don't clean with abrasives, I only use a damp handiwipe cloth with baking soda.


I have had GE washing machines which died an early death as well. So as far as I am concerned GE products suck big time.

Do a consumer report check on them to get an idea what is a good product. Also ask friends and family what they have etc. I think buying too cheap is a big mistake! Made in the USA is what I look for. With used microwaves there is a potential for safety issues.You don't know if they leak radiation.

Amandablue has a good point about used microwaves so I will add that if you are going to purchase a used one be sure to check out consumer reports for that company and model and check that the seals are in good order.

I try to always buy USA made products too but, not trying to be mean or unpatriotic, both GE and Emerson products are USA companies.

Go to the website and put in your microwaves info and they probably have some ideas for you to try. If not click contact us and either call them or email them. I just did that last night for my brand new printer. they emailed me back within a few hours, it didn't help so i called them, it's all taken care of no problem.


If its still under warranty they will replace. I got a heating pad replaced because it would work in low but not on medium or high. I paid to send it back to them but they sent me a brand new one so I didn't complain. If its under 3 months old the store may replace it. Walmart does on furniture and I think appliances, not sure on that. I would try all that before I replaced.

Exactly the same thing just happened to my Emerson microwave. It is now nothing more than a count-down timer no matter what buttons I push and how often I unplug it. Child lock is not set, so that is not the answer. Did you ever get an answer to this dilemma when your microwave did this?

Just subtract 1 second from the time you want to enter.
For example, if you want to cook something for 3 minutes, enter 2:59.

Hey Southern Saver! That is the first think I thought of, too!


I guess great minds work alike and this is a cheap and easy fix.

I am also chiming in that the first thing I thought of was Southern Savers advice and there's no repair time or cost involved ;-)

Step 1
Using a multi meter you will need to test the motor for continuity.

Step 2
If the glass tray is not turning, there could be a problem with the drive coupling. It might be broken.

Step 3
Gently pull the coupling off the shaft of the drive motor.

Step 4
Inspect the drive coupling for damage

Step 5
Replace the drive coupling if it is damaged or broken.

I have a one year old GE microwave that works fine, once, then I have to unplug it for approximately five minutes. After five minutes or so, I plug it back in and it works perfectly, once, but then I have to repeat the process: unplug, wait, plug it in, and use.

Any guidance is appreciated.

there is a you tube vid that addresses this problem. I repaired mine by wrapping paper around ribbon cable that connects to control panel about a year ago. It has worked fine since.

Sometimes the reason for the start button on your microwave not working can be detected though some careful examination of the latch. Otherwise the choice comes down to repairing it or buying a new one. This is a page about microwave start button does not work.
