Question about KitchenAid Microwave Ovens

1 Answer

The unit made a loud humming sound and then stopped working. The display window showed an F4 as the issue. The display area is still functional but you can not change anything using the dial such as the clock.

    I am pretty sure the display showed an F4 as the problem, you reference an E4 did I read it wrong?

The error E4 which showed up in the display is for the faulty humidity sensor.you will have to replace this sensor.and about what you called the loud humming sound that came because the internal magnetron element got shorted.so it has to be checked and then replaced. ------------ to check the humidity sensor you can click this link directly.see on page number (547) its mentioned how to check the humidity sensor.

I have a "continuous" humming sounding when units are heating. The sound is very loud


The humming sound that occurs may be similar to the annoying buzzing my GE microwave produces at random. It could be mechanical vibration. Doesn't seem to affect cooking.

KitchenAid KCMS1555RSS stopped heating. Everthing else works, full display works, time counts down, turntable rotates, light comes on, etc. but no heat. makes loud hum. Magnatron? Cost to replace? Unit is...


If it is making a loud noise, check the diode and magnetron for damage.
BEWARE OF LETHAL VOLTAGES!
The fault may be just the diode and a reasonable cost will be involved. If it is the magnetron, depending upon where you purchase one from will command the price.
Hope that helps.

Microwave does not heat


Hi


Thanks for using FixYa. Microwave not heating properly is caused by a power relay going bad, cold solder joint on the board and/or magnetron (this is only if it makes a loud hum/buzz sound). Also the door hooks and the door-release button should be checked. Please do rate the solution if the issue is resolved or post a comment for further assistance.



Thanks

What does F4 on microwave display mean?


This Kenmore is made by LG for Whirlpool. Confused yet? :D

F4 means you have an open humidity sensor.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

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

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

But Sears parts can usually be obtained for far less here by entering either the part number.

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

It makes a sound when on and smells like burning


If it's an arcing sound, there may be grease or food particles on or behind the waveguide cover or in the area of the turntable motor.

Otherwise, it's likely to be a failing high voltage part:

- A sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound. Usually it will not heat is this is the case.

- A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but if this were the case, it would not heat.

- Sometimes a high voltage transformer will cause a loud hum and burning smell, too.

Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

To allow us to help you effectively (at no charge), please post a
NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, and your specific symptoms.

Let us know which of the examples we gave seems to be closest to the sound you're experiencing.

Everything appears to be working with our microwave except it is not heating or cooking. All other functions appear to be o.k. I am not 100% sure of the model number and I'm not at my house to get that...


To allow us to help you effectively (at no charge), please post a NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, your symptoms ("runs but no heat"), as well as the answers to these questions:

- When you try to microwave are the inside light, internal cooling fan and turntable all working?

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

(A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.)

We have a sound clip here of what a microwave should sound like when the cooling fan and high voltage section are working.

GE JVM1850CH06 microwave no heat with loud humming sound


With the details you described, the high voltage diode might be shorted( usually HVR 1X). It is connected from the Capacitor and the chassis, or else the capacitor is the one at fault,but not common .

Not working plmv169dc


HI, the sound you herd was the noise filter and running diode. these important components have failed at this point. you will need to replace these components asap, if possible. this will fix your issue.

The Magnetron Cut-off fuse will need to be replace as well. this will blow if there is a malfunction within the unit.

Maytag Rangehood Microwave Loud Humming


Sounds like you just fried your magnetron. Normally when they go bad, they make a very loud noise like what you described. The smell concerns me because you may have ruined the waveguide as well. If the magnetron burns through the protective painted surface of the waveguide, the waveguide is ruined. In most microwave ovens this means replacing the entire unit because the waveguide is not replaceable. Putting a new magnetron in a damaged waveguide will result in the same arcing and eventual failure. In addition to the magnetron, the following components are part of the same high voltage network: HV Transformer HV Diode HV Capacitor Magnetron Thermal Cut-Out Any one of these components could have also been damaged. I DO NOT recommend taking any voltage measurements inside the HV network. Potentials of over 4000 volts can be reached and make it very dangerous for the do-it-yourselfer. Taking resistance readings with the unit unplugged is strongly encouraged. If you decide to pursue a repair, inspect the magnetron tip and inside of the waveguide first. If the magnetron is melted and/or there are burn marks inside the waveguide, a new microwave may be a in order. This actually may be a better option than an expensive repair. I hope you find this advice helpful.
