JTP90SP1SS 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. :)

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!

I feel like Macho Mom. I called in the repair guy since I was afraid of dealing with the gas. HE repaired one item but could tell I was comfortable fixing things and pointed out that the gasket was brittle and would cause major problems if not replaced. Took longer to order the part than do the repair, don't know what I was afraid of!

bought a fuse but that didn't solve the problem. Guess I need a new microwave

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

Lifted up the glass plate. Put in the new roller guide. Set the glass plate back in place. Repair done in about 30 seconds! Thanks for prompt service in sending the new part. My only regret is that the part was expensive, and I have already replaced it once before. The new part is still plastic so will probably need to be replaced again.
