Q:

Oven Element Issue 628 4528590

Q:

Kenmore 721.67902601, serial #206KM00696 countertop microwave convection oven

A:

I can understand the usefulness of a service manual but those resources are generally reserved for our technicians. They may have meant an owner's manual. The reason for this is that microwave ovens are very hazardous to work on. I recommend that you have a service technician diagnose and repair that internal component failure. Microwaves contain high-voltage components that can retain a lethal electrical charge of up to 2200 VAC -- even when the microwave is unplugged. Repairs and adjustments, even minor ones such as replacing fuses, can cause microwave leakage. A microwave shielding leakage test should be performed after any microwave service. Keep in mind that an expert will be responding within the next two business days if not sooner and will likely offer you more information and instruction. I hope this information will be helpful and have a nice day.

Thank you for your question and I understand your concern.

I'm sorry but we do not provide technical assistance on microwaves nor would we provide a service manual or technical data sheet.

Microwaves contain high-voltage components that can retain a lethal electrical charge of up to 2200 VAC -- even when the microwave is unplugged. Repairs and adjustments, even minor ones such as replacing fuses, can cause microwave leakage. A microwave shielding leakage test should be performed after any microwave service. 

It is for these safety reasons that we are unable to guide you in microwave repairs and instead recommend scheduling service with a qualified service technician. 

You can schedule service online with Sears Home Servicesor by calling 1-800-4-MY-HOME. 

We thank you for your understanding in this matter and hope we can help you with other questions and repairs in the future.

I hate to ask this, Joey S. and Henry, but why did both of you give out the same misinformation about microwave ovens being able to put out 2200 VAC even when unplugged? Because the wording is exactly the same from both of you, I assume you copied and pasted from an identical source, but why didn't either of you notice the error? Changing the fuse can cause severe electric shock if the wrong things are touched, even if the AC power cord is unplugged, but how can that cause microwave leakage, unless a klutzy person hits the magnatron or oven cavity enclosure hard during this service? I just want to know why holding the oven door open about 1/16" to 1/8" causes the interior light, turntable, and magnatron cooling fan to run. The magnatron itself does not turn on when this happens. Opening the door farther turns off everything except the interior light, and closing the door completely turns off everything. Is this normal for this design, or is the primary interlock switch misadjusted? I don't plan to work on this oven myself but just want an explanation why the door interlock system behaves the way it does, especially when it seems the design provides the secondary interlock switch with no redundancy, except for maybe the monitor switch that's supposed to blow the main fuse in case power is applied to the magnatron when the door is open. I base this on a schematic of another microwave made by the same company. If my reasoning is wrong, please specifically point out my mistakes, based on the actual oven or its schematics. And contrary to what you said, Lawrence promised me a service manual.

Anonymous; I'm sorry but it's against company policy to assist customers in working on microwaves for your protection. I recommend calling a service technician to diagnose and repair your microwave. Any microwave with a high voltage capacitor such as your model can store huge amounts of voltage even after unplugging the microwave which can cause serious bodily injuries or possibly death. The risk is too great and we do not want you to have an accident and this is why we do not assist in troubleshooting microwaves.

But why don't you explain how an unplugged microwave oven can put out 2200 VAC? I believe one of you know it's impossible. As I've said, I don't want to repair this product myself because it's still in warranty, but I'm seeking information.because I don't want to waste a trip to the repair center or risk having the product damaged by them, as has happened in the past with Sears repair service. And contrary to your false claim, I was promised a service manual by e-mail. Either provide it, or deduct its cost from charge for the original order.

J; There is a high voltage capacitor behind the control that can store huge amounts of voltage even with the microwave disconnected from the voltage supply. If you were to touch one of the leads on the capacitor, it can discharge and provide a huge amount of voltage which can cause bodily harm and or death. I added a link below to read over.

I know about the high voltage capacitor in the magnatron's doubler circuit and how it can remain at high voltage even after the oven is unplugged, but I don't understand how it can retain _AC_ voltage, as both of you said it could, and your resume, Mr. Joey S. indicates you have an excellent understanding of the difference between AC and DC.

J; I know the difference between AC and DC, the bottom line is that we do not assist in diagnosing or providing any instructions on how to access and repair microwaves.. Call a service technician to diagnose and repair your microwave or take it in for repair.

If you actually knew the difference, why did you say that an unplugged microwave could generate 2200 volts AC instead of DC and never explain your mistake? It makes absolutely no sense to claim that Sears provides no diagnostic help here when it has "experts" answering these posts.
