PT970SM1SS General Electric Microwave Oven Combo - Instructions

Very fast very easy. Part was exact match!

removed the glass turning plate. removed the broken roller guide. replaced with the new one. I am very happy with not only the ease of fixing the problem, but how quickly I got the replacement part. I will use PartSelect again!!! And I will tell my friends.

Easy

Turned the wire protector to the side. Turned out the old bulb and replaced it with the new. Turned the wire protector back in place and I'm like new.

Replaced the fuse. Result; did not fix the problem.

Replaced it

Replace the fuses

Remove the microwave cover. Requires a phillips screwdriver and a torx security bit/nut driver (there are two security type screws on the back...guess they don't want you to do this at home!). I had to buy the a security bit set (about $7). The diode is easily accessible on the right side under the fan. Requires removing on small phillips screw and unplugging on electrical connection. GE provides some instructions in an envelope on top (after cover removed). There is a warning/instruction to discharge the capacitor before service. This was not a problem for me. Actual diode replacement took 30 seconds. Whole job = 15 minutes.

Replaced the Oven light housing. Unscrewed the two screws that hold the housing in place. Pulled out the housing and disconnected the wire tabs from the light housing tabs. Slid the wire tabs onto the tabs of the new light housing fixture. (Each tab is fitted to the tab in goes on so they can not be mixed up) Pushed the housing fixture back into place and screwed the housing into place.

Convection fan came loose from the shaft with a lout rattle and grinding as the fan spun down. Had to remove four metal screws to remove the fan cover. Initially tried to just put the nut back on to hold the fan. However, I could not get the nut to start, so I assumed that threads were stripped on the nut or the shaft. Ordered the replacement nut, hoping that it was the nut that was the problem. However, I had the same problem with the new nut. I could see no damage on the shaft. It finally occurred to me that the nut and shaft had left-hand threads (counter-clockwise to tighten). At that point, it was extremely easy to put the nut back on and tighten it. I did not try using the old nut, since I had already received the new one, but I'm certain that if I had come to that realization earlier, I could have saved time and money. So, if you have the same problem, try putting the nut on "backwards."

I think I could have managed with just the diode but since I had to pull it I decided to replace all related parts per my research. The Magnetron more than likely was fine.

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!

Ordered new probe

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

Simply remove the broken turntable roller guide from the rotor and put in the new replacement -- less time than opening the box!
