Whirlpool accuwave has started heating food slower. it now takes about twice the time to heat something up as it did a month ago. The MW is about 5 years old
It will need a magnetron and maybe a large capacitor soon
SOURCE: Less than 5 years old
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.
Testimonial: "Quick and accurate! Will go ahead and replace the entire unit. Thanks REPAIRMAN45!"

If the food in the cooking compartment is not heating at all, then you may have one of several components related to microwave energy generation that have failed or became disconnected internally.
Magnetron Tube, HV Capacitor, Filament Transformer or any number of sensors that disable power to the system. The control board could also cause the system to noty function correctly.. You wanted general inputs.. there ya go.. LOL
Not sure I told you anything you didn't already know but you should ask the tech what he did after he gets it going...

Chances are you have a bad magnetron.
If
it's within the magnetron portion of the warranty (usually 5-9 years)
but out of the original full warranty (usually 1 year), then your
manufacturer will cover the part cost, but not the cost to visit you or
the labor charge to do the work.
If
you or someone you know decide to look into it, we have critical safety
information, info on door switch diagnosis and replacement, and
disassembly information at our site, and our link is at our listing here on FixYa.
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.
We're happy to help you and we'd appreciate your
thoughtful rating of our answer.

Just had the same experience with the identical model. Removed the cover (a challenge because of the security screws), revealing valuable troubleshooting directions intended for an experienced technician. However, I think the info is well within the reach of a typical DIY person, does not require any dangerous power-on conditions. However, make sure that you discharge the HV capacitor before trouble shooting. In my case, it appears that the HV diode is open, have ordered a replacement on the internet for $3.18, easy to replace. Hope it works. 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
