How many pounds in one bulk of potatoes - In Microwave Ovens

hi Judy.
Put in the large pot as you peel and slice so they don't turn brown. Be sure water covers the potatoes by 2 inches, on medium-high heat and bring to a boil. Reduce to medium-low heat, cook the potatoes for 20 minutes until the potatoes are soft and fork tender. Turn off the heat, and drain well in a colander.24 Nov 2015

you put peeled potato in it for a while, than take it off, the potato will absorb all the salt.

I haven't heard of such a thing. You must have cooked it until there was no moisture left in the potato. That would also account for the failure of the oven. It would be the same as no load in the oven.
A thermal protect part is your current problem.

If your microwave is not a convection then the moisture most probably is somehow getting to the controls as potatoes has quite a bit.

Put the potatos in a zip lock bag

If this microwave is a convection oven, you don't give make or model, treat as a fan assisted oven. 20 minutes per pound and 20 minutes extra for the meat, veg is best microwaved for a few minutes except potatoes, put them in the dish with the meat. Cover to stop splashing and set temperature to 190 Celcius 370 in proper temperature.
I am getting hungry now!
Enjoy.

yea you can bake sweet potato in it on the pan 30 min. on each side.

the magnatron super heated the paper combined with what we in the industry call super combust your micro should be ok to use just keep it clean and if you use toweling wraP it around rather than cover

Not much info to go on here. Are you putting in the number of potatoes vs.the cook time? Most microwave potato functions would not read "5 minutes." It would be read as a request to cook 500 hundred potatoes.

After washing you need to poke holes in potatoe skins or the steam can cause them to explode. Cook potatoes no longer than 6 to 8 minutes depending on your units power.

Microwave ovens can be very dangerous if damaged, so you will be safer to replace the unit. Better safe than sorry. Service on microwave ovens is not cost effective, and the newer ovens are very reasonable.
