Question about Whirlpool GT4175SPS Stainless Steel 1200 Watts Microwave Oven
Our microwave is just 2 years old, a built in model. The timer counts down, the light comes on and the turntable turns but there is a raspy sound and the food does not get heated. We had just fixed a door problem 6 months back.
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.

If you don't have electronic experience is to dangerus, you will needs a Technician to chek: If 110 volts sypplying the big transformer, if yes check the output of this transformer, if have high voltage the transformer is good, then have to check: Magnetron, high vontage diode and big capacitor. I'm sorry this is not easy to no experience person. I'm sorrry for my English not so good. I hop you solver ou problem.
