Kitchenaid YKHMS2050SS - 2 Our 9 year old Kitchenaid microwave YKHMS2050SS-2 does not heat food. About a month ago, it began beeping and selecting random screens and options when nobody was near it; it never turned itself on. Recently when reheating food, we heard a 'pop'. Everything continued as normal but the food had not heated up. When we tried the microwave again, we noticed some steam or smoke inside the oven and a slight burning odour. A black spot has appeared at the edge of the piece of silver coloured material located on the inside top. What are the likely causes of these two problems the phantom display selections and the lack of heat and the approximate cost for fixing each one? What is the expected life span and reputation of this microwave? We are wondering whether a large repair bill is worthwhile or if we can anticipate future problems or failures in the near future. Thank you for your advice.
Frances it is possible to fix the issues you have described,although..having a 9 year old unit which likely has door leaks emitting harmful microwave energy ,along with other age incurred operational issues. I STRONGLY recommend replacing your microwave just in case.. Marcus
I'm sorry to say that it's most likely the magnetron that's shorted out (the high voltage device that produces microwaves). It's usually the case with ovens this old that a compatible replacement won't be available.
There's also the fact that your oven is likely way past it's 'end-of-life' date so even if you could find a replacement, other components will begin to fail as more time passes.
In short, save yourself the money, time, and frustration with a new unit. Good luck!

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help

Small component called a diode. Open up the microwave and try to find a black (usually) component that is most often connected between the magnetron (the thing that heats the food) and the chassis of the microwave oven (ground). I used to make a fortune replacing these! Costs about 5 bucks most appliance supply stores. Make darn sure you get one of the same value.

If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven. This is what produces the RF energy that heats your food.
Here's what you need to determine whether or not its worth fixing:
1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
2. You will need to ensure the oven is UNPLUGGED before servicing anything inside the cabinet. You will need to remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
3, The magnetron replacement part number for the model you have listed is WB27X10305. The average cost is about $80. NOTE: I found the part listed for the best price at appliancepartspros.com at a cost of $76.
You need to decide whether or not $80 and the amount of labor involved is worth the effort as opposed to replacing the entire oven at a higher cost and less labor (other than the installation). Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble.
If you have any questions, please post back and let me know. I hope you find this information helpful
CAUTION: DO NOT operate a microwave oven with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts.
Testimonial: "Hi jsrock516 - thanks for your expert information. I don't think this is something we can fix on our own and as you said probably cheaper to replace. "

That pop was the magnetron frying. This is a repairable problem, but feirly expensive, around $300 if you have it done by a professional.
Please rate my response if it was helpful to you.
Thanks, Repairman45.
