Product review (5 stars): Very pleased with this product!
This switch worked great on my 6 year old Whirlpool countertop microwave model GT4175sps4.  When I called Whirlpool they told me to buy a new microwave instead of trying to fix it. A new microwave that would fit my cabinet would of been 229 plus a new trim kit at 120 plus tax.  For 2 switches I spent 16.50.  On YouTube they showed how to troubleshoot and also how to install the new part.  Was very easy to do.  The best part is the satisfaction of fixing it yourself.  I only used one switch and now I have a backup as the repairman on YouTube said 75% of microwave repairs are the switches.
