Question about Microwave Ovens

1 Answer

Daewoo KOC1B0K We have a Daewoo KOC1B0K and when it is operating everything works fine except it doesn't actually microwave anything at all. The clock, turntable, timer etc all work but it doesn't cook. A faulty Magnetron has been suggested but we'd like to know if anything else could be the problem. If it is the magnetron is it easy to replace oneself or should a professional be employed? Thanks

    Light is on and turntable moves. The noise is exactly the same as when it used to function normally - the only difference is that it does not heat anything.



    Thanks

    Do the inside light and turntable come on when you try to cook?

    Is it making any unusual noise or is it louder or quieter than normal?

In that case, the most likely problems are:

- loose or corroded connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron
- shorted high voltage diode

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Microwave lights, clock, and everything works except when you press start, it just counts down like its cooking, but the microwave is actually not on. No hum as usual or plate rotating. It just counts...


Hi, one of the most common reasons why the turntable won't rotate is that the microwave isn't clean. The turntable guide and carousel can get sticky, preventing the turntable from properly moving. If you have built-on food particles or liquids, fill a bowl with 2 or 3 cups of water and 1 tsp. of liquid detergent and lemon. Run the microwave for about 3 minutes. Clean the microwave with a cloth, including the base of the turntable, guide, carousel grooves and microwave base. Your microwave turntable won't rotate if the grooves on the base of the turntable do not sit right on the carousel. Also, check the position of the turntable guide. Place the guide directly under the turntable. Remove the turntable, and then reposition it into the carousel grooves.
Motor The carousel motor is located beneath the base plate of the microwave. If the carousel isn't turning at all, check the motor. Disconnect the microwave from the power source, and remove the turntable, guide and base plate. Try turning the motor to see if it's just stuck. If it doesn't turn freely after a few seconds, examine the motor to see if it's burned out or corroded. Use an ohmmeter to see if the motor has continuity. If not, you must replace the motor.
Bushings The drive bushings are plastic components that sit underneath the cooking plate. Remove the plate, and examine the bushings. Use a magnifying glass if necessary to see if any debris is caught in the plastic. Clean the bushings, and reinsert the plate. Turn the microwave on to see if it rotates. If the bushings are extremely worn or if some of the plastic is broken off, you need to replace it, which is a complicated repair for consumers. Contact a service technician for assistance.

Doesn't heat anything


It sounds like the micro generator has died.

Yes, you should buy a new one as the cost of repair is likely to be high.

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also


if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

Sharp 1870 just quit cooking and no turntable


The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

Everything works except the cooking part/no heating/turntable not turning, help!


you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt

Daewoo MT1510B problem


Chances are your magnetron is overheating, activating the magnetron thermostat, which resets and restores power when it cools.

Your manual may call for you to put a paper plate under the popcorn bag to heat better and to protect the turntable. (And always place the food slightly off-center on the turntable, for the same reasons!)

You should first confirm that the outlet reads about 110-120 volts AC and that the microwave is on its own breaker. If a microwave shares a breaker with another high current device (or even lights) it can affect operation.

Then be sure the microwave's internal cooling fan is running.

If this is an over the range model, it will also have a exhaust hood vent fan which you can turn on and off at will, but this is not the fan I'm talking about.

The internal cooling fan should be on whenever the oven is cooking. If not, the magnetron can overheat and eventually be destroyed.

The next issue is how long you've had the oven.

If it's within the 30-day dealer exchange period, I'd take it back for a new one pronto.

If it's within the full warrranty period (usually 1 year) Daewoo's service center should fix it free.

You can visit Daewoo online or call them at 1-800-323-9668 or 1-800-553-4355 to find parts or find your nearest authorized service center to have them do the work.

GE microwave oven


Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
