JTP90BM2BB General Electric Microwave Oven Combo - Instructions

opened the microwave door, removed the glass plate, removed the bad roller quide, replaced with the new one, replaced the glass plate and then closed the door. :)

it was a simple screw in on both ends. no soldering

First of all, the sensor had the proper ohm reading...at ambient temperatures. I suspected the sensor because it would jump in large degree increments over 200°F. From what I read online, the only other part that would cause this was a faulty circuit board. I opted to try the $20 part first vs. the $200 part. It worked. One screw on the back top of the inside is all that holds the sensor in. Pull the wires out and you will find a quick-disconnect. New part had the same connector (thank you). Thread the wires back through the hole and replace the screw. Works like a champion (verified with an independent thermometer. That is all she wrote. I only wish I purchased two, since they don't last that long... 4 years...or so. I just bought the house built in 2007 and empty for a year... and it took 45 minutes to cook a pizza, and even then the bottom dough was light. A house without an oven is like a hot dog without mustard!
