Does anyone know where I can order used whirlpool gas range repair parts ,without having to takev out a 2nd mortgage?

Why would you put used parts back to replace used parts that failed? If you need to follow that route, go to a used appliance store or check Ebay or Craigslist.

Have you ever looked for new or used parts on eBay or craigslist?most of them go for as much as new parts.I`m in my 60`s disabled and my income is $600.00 dollars a month,so I can`t really afford another stove or a new part.what I need is a oven gas safety valve.whirlpool parts for some reason are worth more than other brands.I just thought that maybe someone else has been in this same situation,and might be of some help to me.thanks for the advice though,and have a great week.

I just looked in my local Craigslist and found gas ranges for free, $25,50 and up.

Here are some manuals to help look up parts and fix it: https://dl.dropboxusercontent.com/u/8010163/Whirlpool_Gas_Ovens.zip
