    Probably a shorted Magnetron or rectifier, or both. Whirlpool has in the past used a small square magnetron that has been quite expensive. In most situations by the time you add up the cost of parts and labor you can replace it with a new unit with full factory warranties. Time to go price shop new units.

The noise is coming from the high-voltage transformer being overloaded by something shorting it out. Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

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.

The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

My Frigidaire microwave model# PLMVZ169GCC does not heat food. It runs and makes a loud noise, the plate turns but does not heat up. It is only 2 yesrs old. Thank you for your help.


Intermittent load noise (usual intermittent pulse noise is exaggerated) and the food is not heating though everything else seems to opperate normally: The Triac or Diode is capute.

You need to replace this part (@$30), but first need to discharge the capacitor, which is dangerous. I am going to give it a "shot", and not a "shock", all the punn intended. I will use an long insulated screw driver to touch both of the 2/3 tines of the adjacent capacitor, which will give a load "POP!" 2-3x to insure the stored energy is diffused.
Then, hopefully, simply replace the longe wire diode.
TaDa!

The unit is 3 years old and when I turn it on there is a loud hum. Theunit also does not heat but turns the turntable?


From your description it sounds like the magnetron has failed in this oven. That's the part the makes the microwaves to heat the food. It typically fails by shorting out and making a loud hum noise. It not usually worth fixing since the price of a replacement magnetron is almost as much as a new oven.

Our Sharp microwave oven turns on, makes a loud humming noise, starts to smell like something is burning, but doesn't heat. Well, actually, we don't think it heats, we're too scared to let it run because...


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman";} This can be caused by grease etc. inside the oven and on the wave guide which is the paper like thing in the oven. If you can remove it look for burnt areas which may can be scraped off or you may need to replace it. An appliance parts store usually has the material you can cut to fit you own.
