You didn't mention your brand or model number, so I can only give you a general response.

It sounds like a shorting membrane keypad.

On Samsung's, they will show the error code "SE".

For detailed do it yourself info and/or an estimate, please post a new FixYa help request and include the model, or contact me here with that info.

Our microwave all of sudden quit working. Had no

Hello :

Maybe there's a problem with the power transformer or the power PCB [ Printed circuit board ] . Or it could be just a fuse . You need to check first . If it's the fuse , then that will be easy to solve , you need only to replace it with new one . But if the problem is with the transformer or with the PCB , you need to take your microwave to the service for repairing .

To locate the fuse, remove the outer cabinet of the unit, which is usually held in place with a few screws. Once the outer cabinet is removed, follow the power cord into the unit. It will take you to the fuse holder, where the fuse sits. The fuse holder is located two or three inches into the unit, and may be attached to a power board .

good luck .

please rate !

'Start' button won't depress, seems jammed; timer knob broke off

the button is stuck because of food buildup over the years underneath the button, this happens even to newer ones after about a year of use, new microwaves are cheap and the lower end models start at only $35 from walmart I would reccomend buying a new one, newer microwaves use less power and are more effecient so a new one will pay for itself in saved electricty costs after about 2-3 years of use.

Arcing Microwave Oven

Look in cavity for any burn marks. If burn marks are present sand and paint area. You have to use paint made for microwaves. If no burn marks, Flash coming from magnetron and it would be time to replace. Yes it can be a safety concern, I would not use until fixed.

No heat from my microwave maytag mmv1153aaw

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)

But if when you start to microwave, if the turntable, inside light and internal light are not on, then you instead have a bad door switch or door switch mount, in which case you should see this:
