Question about KitchenAid KCMS2055SSS Microwave Oven

1 Answer

Timer runs 10 times speed

After re-setting clock on m/w, the cooking timer now runs at about 10X speed & magnetron doesn't seem to come on. Timer runs regardless of how cooktime is selected (add a minute, key time, or pre-sets). This unit is 22 months old. Worked fine until I re-set the clock! Haven't powered it off yet since it's a wall mount & haven't taken trim kit off to get to power plug.

Sounds like a classic bad door switch or switch holder. If you or a friend decide to work on it, we have *critical* safety info, info on door switch testing and replacement, and oven disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383

SOURCE: Sounds like it's running but no heat

Those symptoms are what I would expect when the controller or keypad gets wet. Tipping it is not an issue, unless that allowed the water to run into the controls more than just the wet soapy washcloth did. You may get lucky - it may dry out by itself in a few days. If not, and if careful targeting drying doesn't fix it, it will need a new keypad or controller.

SOURCE: Kitchenaid always shows "CLOCK SET", I think keypad is STUCK

F2 on a newer Whirlpool / Kitchenaid microwaves means you have a shorted keypad.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs.

But please note that for some models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame which comes with a new keypad.

In this case, you simply move your circuit board into the new frame.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: Microwave beeping and F2 error code

hi,
The F2 code is a keyboard failure. Since it's intermittent I would check for a loose wire/connection. open the control panel and reset the ribbon cable on the circuit board....


thank you,

Sharp convection microwave oven model R1875F. It's cooking on the left side faster then the rest of the oven. It seems to burn on the left side and not cook in the middle.


see the next causes. God bless you
Diode The high voltage diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron which emits the energy that cooks the food. If the diode burns out, a lower A/C voltage reaches the magnetron, which is not sufficient to power the magnetron. When the diode fails it is often visibly burned out. If it appears to be good, it can be tested with a volt-Ohm meter capable of testing diodes. High voltage diodes frequently fail and are one of the most common points of failure in a microwave oven.

Door Switch If the microwave does not heat, one of the door switches might be defective. Microwave ovens normally have three door switches, if any of them fail the microwave does not turn on and does not heat. Check the switches for continuity with an Ohm meter.

Magnetron If the microwave oven doesn't heat the magnetron tube might have burned out. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the microwave oven is turned on when it is empty this can cause the magnetron to burn out. Once it is burned out it has to be replaced, it's not repairable.

High Voltage Capacitor If the microwave doesn't heat the high voltage capacitor might be defective. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor is burned out the entire high voltage circuit stops working properly. The high voltage capacitor can be checked with a special VOM meter which has a capacitance testing capability. Be aware that the high voltage capacitor can retain a charge of more than 3,000 volts and can injure or kill a person if not handled properly. Only trained technicians should perform this type of testing.

High Voltage Transformer If the microwave does not heat, the high voltage transformer might be burned out. Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food.

Thermal Fuse If the microwave doesn't heat the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.

Thermoprotector If the microwave doesn't heat the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

Main Control Board If the microwave doesn't heat the main control board may be defective. This is not common. When a microwave doesn't heat the problem is usually within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.

Microwave wont heat up food


If your microwave runs, but doesn'theat your food, verify that you have selected a cooking setting. You mayaccidentally set the timer. Test the magnetron by placing 1 cup of water in themicrowave and heating the water for three minutes. If the water doesn't heat,your magnetron is dead.

I have a Siemens microwave (inno-wave). When I try to cook something, say I set it to cook for 2 minutes, after 23 seconds it stops and reverts back to the digital display clock. It seems clear during that...


The controller is probably sensing that the magnetron is not drawing current and shutting down the timer.

The magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Microwave runs but does not heat or cook food



If a Goldstar, LG or Zenith MV1610 or MV1608 is running but not seeming to heat a load placed in center of turntable, its probably because the "stirrer" intended to spread microwaves generated by the magnetron around the cook chamber is stuck so that most all the heating is directed toward the back and top rather than the center of the cook chamber. This usually occurs after cooking for longer than a minute with no load in the cook chamber - as when a model w/o a timer (such as a MV1608) is intentionally operated in cook mode to serve as a kitchen timer, or when a model with a timer function (such a MV1610) is accidentally operated for longer than a minute w/o any load. Before assuming the magnetron (usually warranted for 5, 8 or even 10 years) or other high voltage component such as diode or capacitor needs to be replaced, try “cooking” a 16 oz pyrex cup of water at full power on the outer edge of the turntable for 2-3 minutes - which usually reactivates the "stirrer" and restores normal cooking function.

Microwave won't heat, already tried replacing fuse. Timer, fan, clock work.


In all probability, the magnetron has died. The magnetron is the part that creates the microwaves that cook your food. Magnetrons are usually covered under a 5- or 10-year warranty and replacing them yourself can be pretty dangerous. I'd suggest you call a technician.

Microwave lights up but no cook!


Magnetron of your Microwave oven may be defective. If there is a fuse between the highvoltage transformer and to the highvoltahe capacitor check the fuse is blown off. If so replace the fuse. If it is Ok change the Magnetron.
