Noise/humming while cooking; especially popcorn; intermitent on other food

I have a Kenmore over the range microwave that I purchased in 6/6 and have had it about 1.5 years. Model 761.80523500 (#80413). It just started making a load humming noise while cooking popcorn. Tried some other stuff like water and it only did it briefly (intermitent).

    Thanks. It looks like it is doing it now for other foods. It is at the Sears Service center for repair. I will keep Fixya posted.

    Just got a status update from sears repair....repair will be delayed due to order of parts..."bushing Kit"....does anybody know what this part is ?? Is it have something to do with the high voltage part of the microwave, insulators ?? Thanks.

  • Y2k600f4 Dec 23, 2007

    Thanks for the input. I was not thinking it was the fan, before I sent it in I investigated it (parts department on the phone told me it was probably the fan; which was $10 if I ordered it) according to the symtoms. However I competely removed the fan and the symptoms did not go away. Maybe I am missing something; I will investigate further.

    Update: Just went to pick up my "repaired" microwave today.....and I found out it was NOT fixed !!! Apparently they now say it is not repairable "inside cavity metal burned near magnitron". Called sears parts and the part (Goldstar) is no longer available. Does anybody know if I could possibly get that part and what would cause such damage ??? Thanks,

  • Y2k600f4 Jan 03, 2008

    To clarify I believe they are talking about the waveguide; right above the magnetron the metal is charred. I know it would need to be replaced (they won't ?) but what would cause this ??

Sounds like a mounting bracket insulator for the fan. Like, maybe they had a recall because of this???? This is not normally a service item. Fight 'em for any charges.

Popcorn is heated by a metallic insert in the bag. This causes some additional power consumption by the magnetron. It is no cause for alarm.

Kenmore microwave 85609 has a 5E code on it
test this steps and fix it. God bless you
  1. Power Issues

    • If your microwave oven won't come on, ensure that the power cord is plugged into an outlet and that the power is on. Replace any blown fuses, and reset a tripped circuit breaker. If the microwave won't run, see that the door is completely closed and that nothing is stuck in it. Ensure that your door is not broken. Replace if necessary. See that you have not started the timer as opposed to the cooking function. Press "Start/Enter" to start your microwave.

    Clock

    • Your display will flash if your power goes out. You must reset the clock. If you do not hear a tone at the end of cooking, ensure that you have enabled the audible tone. Also check that you are using the right command. If your power goes out while your food is cooking, you must reset both the cooking time and clock.

    Cooking

    • If you see sparks while you are cooking, remove any metal objects or plates with silver or gold trim. If your food is taking too long to cook, ensure that you have selected the correct power level for the food item. Remove any other appliance from the 20-amp circuit line. Additional appliances on the same amp will draw too much power away from the microwave. Also ensure that you have selected the correct food item in the preprogrammed menu. Each microwave has its own error codes. Always read your manual to determine what the error code means. Examples of error codes include "E-11", "E-12" and "E-13." This means that you have a defective sensor, and you must get your microwave serviced. The "SE" error code indicates an issue with your control panel.

    Additional Problems

    • You may hear gear noises, especially a humming noise; the fan will automatically come on while your food is cooking. If your turntable plate makes noise, first clean it, and then see that it is positioned correctly over the roller ring. If your nearby appliances are experiencing electrical interference, move your microwave farther away to correct this problem.

Spacemaker (JVM1871SK) 1800 Microwave doesn't microwave
Remove the case and see if you can localize the smell. Likely suspects are a shorted high voltage diode (replace) or a shorted stirrer bearing (replace stirrer)--a fan-like device located within the sheet metal waveguide near where the microwaves enter the cooking cavity. Make sure to have a cup of cold water in the cooking cavity when looking for problems. The problem could also be the high voltage transformer or the high voltage capacitor, but these are more rare problems. There are no radiation problems with the case off, but there are high voltages associated with the magnetron and it's power supply.

Bad to cook popcorn in the microwave?
I have run a lot of popcorn thru the microwave with no effect on the oven.

I've never seen any cautions to not do that or to even be careful doing it.

A lot of microwaveable popcorn is sold, so that's a good indication.

GE Spacemaker XL1800(JVM1850CF001) - Loud Humming noise
You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

Toaster Master 1979 has less power
Because the microwave energy is beamed into the interior of the microwave and then dispersed by a metallic "stirrer," the pattern of the energy can be fairly consistent, rather than completely random. But this pattern sometimes causes certain portions of the food to overcook (creating tough spots) and others to undercook. A microwave oven with a carousel is far better at cooking the food consistently--the pattern becomes quite random while the carousel is turning.
