Whirlpool gold GT4175SPS-2 inside door paint is flaking and revealing metal. Is it safe to use?

It's not door switch. It's the microwaves are not being produced. Do to safety issues DO NOT take apart. Replace

There is not any power in the door itself. However if the chassis has chipped paint or corrosion the RF from the microwaves magnetron will cause those bare metal areas to reflect the concentrated RF energy and cause sparking.

The only Whirlpool Microwaves that have been recalled, has a model number beginning with XC and had a green sticker on the bottom face area of the chassis where the door closed.

I have often been able to clean and paint the bare metal areas with the correct paint to stop the RF reflection sparks. Using the model number above it is white enamel "appliance paint" that you would use to paint the bare metal areas. A word to the wise.... do not sand outside the area to be painted. Otherwise you re-introduce your current problem post repair.

The model number you passed is missing the very last digit that would be from 0 to 7 (Eight models)

whirlpool microwave keep working when door open why

Hi,

It sounds like there may be a diode or relay on the control that has failed. This could cause both symptoms you are explaining here. In either case the control board/keymembrane would need replaced. The cost of these would be about $173.00 for parts. Unfortunatly this repair would most likely cost more than the value of the product. Sorry for the bad news.

If the metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Otherwise, you may get rust and/or arcing.

Ok stop useing oven and unplug! THIS CAN BE FIXED!!! Go to a home improvment store and buy a small bottle of white liquid enamal....Clean up the area that is missing and flakeing and then apply the enamel over the hole and let dry overnight! now that the exposed metal is covered back up it is safe to use and will not spark or cause any more soot!
PLEASE rate my response to your question!
THANK YOU!

just use sand paper to clean the rust then use some high temperature paint (sold in tins) eg spray paint but it must be labeled high temperature and spray 2 to 3 coats . your microwave should be safe again

It would be dangerous to do so. Any exposed metal inside a microwave is source for sparks and is extremely hazardous. I would recommend getting the paint job done up, or even better, buy a newer model.
