Samsung model mr1034ubd

get a tape measure and measure thea external dimension of the dead microwave
go to a retailer and measure the dimensions of new microwave ovens and one with the same or slightly smaller dimension will fit in
the power or wattage of the unit is of little consequence but don't get smaller than what you had but a a bit bigger will be good

best bet is to take a tape measure and measure the width , the height and the depth, write down those measurements then go to an appliance shop and measure all those on display

Use a tape measure to get the measure ments..use that information when shopping for a new one.

Measure what you have and compare those measurements against those of the new one. Then you will have the answer to your question.

Almost all over the range micros are 30 inches wide. They did make a few 36 inch models but most are 30. Top to bottom back measurement can be between 16 to 18 inches. Most makes are similar in size. Back wall mounting plate will have to be exchanged since each company has a slightly different design but the wall plate comes with the new unit along with mounting hardware.

Take your measurements and compare them to the measurements from various microwaves online, then go to the store that has the same measurements. I wouldn't use the microwave for fear of a fire.

You can do an exact power measurement by putting exactly
500 ml of water in a glass (Pyrex) or plastic measuring cup in the microwave. Measure the beginning temperature and record it, preferably with a digital thermometer. Run the unit on high for exactly 18 seconds. Use a digital watch or a stop watch, not the timer on the unit. Remove the measuring cup and stir the water to make sure that all the water is a uniform temperature. Record the temperature rise. Say the temp rise is 20 degrees Fahrenheit Multiply that figure by 38.75, this would indicate that the power delivered into the cavity is 775 watts. This is the old standard of measuring the power. The new standard called the IEC 705 would add 10% to that for a total of 852.5 watts. This matters more than the rating of the unit because if the power output is more than 15% below the units rated power, the magnetron is probably getting weak and needs to be replaced. Probably not worth the cost to repair. The voltage at the wall could also cause a low power output output. 'Google' the model # to see if you can find any info on this model #......

If I had a tape measure and was with your microwave or knwe what make and model it was, I could help you but I am neither and cannot.

Is the interior flaking the only problem with it?

It can be sanded smooth and clean and dried thoroughly, then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Otherwise, if you want to replace it, I would suggest contacting Jenn-Air Customer Care here and telling them your model number.

They can probably give you the model number of a new "drop-in" replacement.
