Won't heat food on any setting. Could it be a fuse? Where would it be located? Don't have a manual.

9 out of 10 times if all else is working then it is the magnatron rod that does the heating chances are it will be more expensive than to purchase a new microwave.

If it has a platter does it turn? (possible safety switch in the door issue) Other than that a Diode, inverter board (diode might be on it) or the Magnetron bad.

emerson mecrowave mw81195bm clock works but I can heat anything it doesn.t work inside

Check to see if it has a DEFROST SETTING if Defrost setting is on it will not reach an adequate temperature

The problem is caused by a bad magnetron, inverter board, "7 years old or less" and possibily the keypad control board.

Nearly (maybe all) small appliances with a heating element are equipped with a thermal fuse. This prevents the meltdown of heating elements, most of which are encased in aluminum. These fuses are not only unreliable (China is the biggest supplier) but generally unavailable as replacement parts since they are most often spot-welded to the ends of the heating element and would have to be replaced in the same way since solder melts at a much lower temperature.
I would suggest you replace the pot.

Hi!

The most common cause of the problem you described is a burned fuse. It is normally located inside the case, directly on a wire leading from the transformator to the magnetron. If you are not sure about those parts, please get a professional to fix the issue.

Good luck!

GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.

Rust can form from the steam and condensation as you say, and it's a good idea to always cover food and wipe the oven out after using it. You can sand off the bad paint and rust the same way you can on a car, and then touch up the paint if it's a minor amount. Spray paint specifically made for microwave cooking cavities is available. (You don't want to use paint that may have metallic components.) It may be available locally if you have appliance parts stores in your area, and you can find the paint online as well. There's no need to replace the oven just yet, unless you find a good deal on a new one and you're looking for an excuse.

The clock must be set before you can use the microwave. When you plug it in, it should read all zeros. Enter the time, and press "Clock Set." Time is in 12-hour format. There is no daylight saving time.

For basic microwave use:
1. Press "Power."
2. Press the keypad corresponding to the desired amount of power, e.g., "High," or "Defrost." (The numbers on the keypad have little words on them, like "Warm," "Med," and "High".)
3. Press "Time."
4. Enter the desired cooking time, e.g., "1-0-0" will be 1 minute; you could also do "6-0" for 60 seconds. You can do as little as 1 second, up to 99 hours 59 minutes. "1-0-0-0" would be 10 minutes. "2-0-1-2" would be 20 minutes 12 seconds.
5. Press "Start."

NEVER operate the microwave when it is empty. Put at least a glass of water in it. Never put a glass in it empty; make sure the glass has something in it, like water. Be careful when taking out a glass of water that's been heated; the water has been known, in rare instances, to "explode" and severely scald people.

It is okay to use the approved metal rack (it's coated with ceramic to prevent arcing) when using the microwave in microwave mode. Of course, the metal rack is also fine for use in the convection/combination mode.

"Defrost" cycles between microwave and nothing, microwave and nothing, microwave and nothing. You can hear the cycles. If defrost takes too long, try "Low." Try to avoid using "High," as it kills most nutrients in the food. Opt for "Medium" for slightly longer time; it'll be more evenly heated and healthier. Some things, like popcorn, require "high" power.

To stop the microwave in the middle of cooking, simply open the door. (There's no such thing as microwaves escaping the oven and bouncing around the kitchen and zapping you. I have a microwave tester, and the moment you open the door, all microwaves dissipate; the reading at the door is "Zero" once it's opened.) Or, press "Cancel." If you open the door, you may test the food, and if it needs further cooking, you may close the door and press "Start," and it will resume where it left off. If you're all done, just press "Cancel."

There is no way to disable the 5 beeps at the end of the cycle. If the baby is sleeping and you don't want to hear the beeps, simply open the door right before the beeps when the countdown is at zero. Pressing "Cancel" will give you one beep.

If you have the Combination feature, that cycles between microwave and convection heat, giving the best of both worlds (cooking inside with microwaves and outside with convection), for things such as a whole meats.

To use Combination:
1. Press "Combination."
2. Consult the chart on the microwave (below the keypad) and choose a number from 1 to 4, depending on what type of food you're preparing (i.e., lamb, pork, etc.).
3. Press "Time."
4. Enter the desired time, using the method described above.
5. Press "Start."

The Convection feature simply blows hot air across the food, at the temperature and duration that you set. It's a great way to toast slices of bread for the whole family at once, or bake a pizza.

To use the Convection feature:
1. Press "Convection."
2. Choose the temperature (the degrees are printed on the keypad, such as "350 degrees."
3. Press "Time."
4. Enter the length of cook time, using the method described above.
5. Press "Start."

Be sure to cover foods (with a paper towel or suitable plastic cover) that are prone to splattering. Don't let foods explode and get up into the motor. Clean the inside regularly with a soft sponge and mild detergent, NOT harsh or abrasive chemicals like Comet. Then rinse the soap off with a clean sponge.

Be sure to close the door firmly before cooking, but don't slam it. Slamming it will wear out the latching part, but being too gentle in closing the door may cause the safety switch to not engage, and the microwave won't work (it'll count down and the light will turn on but the motor won't run).

Note: the Convection feature uses more wattage than the microwave counterpart. The volts and amps are listed in the door jamb; multiply them together and you get total watts (although the actual amount will vary depending on your "power" settings).
