I have a Sanyo microwave, EM-S7595S, and it does not start. All the control panels are working, the inside light is working, but when I push the start button it does not start.

When I close the door, the inside light also turns off. Does that mean that the door is closed properly? While inspecting the latches I noticed that there is one bottom latch. Is it supposed to have a latch on the top as well?

What else could go wrong. Please advice.

This might not be your problem, but who knows? I had a similar situation several years ago. Everything seemed to be working till I shut the door and pressed start, then nothing. I asked my son to check it out as he is/was an electrician. Sure 'nuff he found the problem. I had a loaf of bread on top of the microwave.

The plastic opening was hanging over the edge. When I shut the door a bit of the plastic was in the way, blocking the connection. Moved the bread and all worked fine. I would check to see if anything however small is blocking the connection.

My start button did not work, after reading some of the answers I checked around the latch and sure enough there was a small piece of plastic of some sorts hung on the latch hook plate. Cleaning it with a Qtip fix the problem right away. Thank you.

After being unsuccessful using all the suggestions I sprayed some canola oil in the spaces that receive the latches. I shut the door and pushed start. It works again.

This could be a fuse issue, with this microwave!

I would unplug it and replug it. That may clear out its memory and get it to work again.

Microwaves are dangerous to repair. Find a blow out diagram of the parts to order correctly: most repair sites have this. T

To repair the microwave, when it does not start means that the latch seat is worn. This is a job you can repair yourself. Unplug the machine and let it sit.

Remove the cover and set aside the screws because they are specific. Do not touch any parts that are active to make microwaves. The part that is worn is where the hook fastens. Remove and reorder the part. Replace. Place cover back on and try MW. If it works screw cover back on.

If your light does not shut off when the door is cloes it is a problem with the latch on the door. The door needs to be latched and closed in order for the oven to work properly. You need to see what is in the latch and if a spring is broken inside it or not.

The buttons will not work if the door stays open and the oven can not start with the door latch broken.

I find it helpful to talk to the customer services for the company. If you find the brand and make and model of the device, you can easily locate their customer services and give them a call (Google usually brings it up quickly with a few key words like the brand and the phrase customer services).

I would not attempt to do microwave repairs on my own, but if it is something as simple as checking a latch, that may be doable.

You don't mention how old your device is. If it is 3-5 years old, I have learned that that is about how long these newer ones last. It is terrible, but true.

I hate to see these get trashed, so my last suggestion is see if you have one of these community repair places that are popping up in coffee shops around the country and if they can fix it.

Here is a link to one of the groups...called Repair Cafes:

How long have you had your microwave? Sometimes it won't be an easy fix and you may need a new one..

My over-the-range microwave doesn't work. When opening the door, the light is not on, but I could enter the cooking time; then when clicking the Start button, the message just appears "Open ... Close", is there an easy fix or should I ask a certified technician to take a look?

In this case it may be the circuit board. But first, try holding the off/clear button on the keypad for 5 seconds for a soft reset.

My Spacemaker GE microwave is working fine when I use 30 seconds, or 1, 2.. minutes, but when I manually add the time and press the "start" button then it's not working, the "stop/cancel" button is not working either. The bottom line is it's only working on other buttons. What caused this issue?


Thanks very much.

It sounds like the sensor to those buttons isn't working. It probably is more cost-effective to replace than repair.

No buttons work on our microwave except the temp control and power button.
We have replaced 2 main control panels and the touch panel. The light comes on in the microwave and goes off when the door shuts. This is a built in microwave that has hardly been used, but is out of warranty.

Any suggestions? At this point we have put so much money into it we are kind of committed. Does anyone know what else could be wrong with it? The start buttons and others don't work but the temp control and power button does. Sure would appreciate any help.

There may be a problem with the membrane switch. Here is an excellent website for troubleshooting microwaves: www.partselect.com/.../

I had a Sharp over the range microwave put in in 2005. Everything works, but the start button. The lights and fans work fine. I called for a tech; they charge $75 for just coming to the door. I am better off buying a new one, unless someone can tell me how to fix it. Any suggestions anyone? Thank you.

Microwave Start Button Does Not Work

I once had a microwave like that and I found the door latch spring broken. The door latch, in most cases must close a switch and this tells the microwave that the door is closed.

As you know they will not work with the door open. A good handy man should be able to check and see if the latch springs are good. (01/20/2010)

Microwave Start Button Does Not Work

Definitely don't bother paying for a repair person and definitely 'do not' pay extra for a warranty on a new microwave because that's just a way for the company to collect extra money for a service that might not be available/in business after four years anyway. (01/21/2010)
