F3 Error message
Two screws remove the front of the sensor (put a pan under the sensor to catch the screws), One nut removes the rear cover to access the rear of the sensor. Separating the two halves of wiring harness takes a little dexterity. BIG TIP! Tie a string to the back of the sensor wire and pull the sensor out from the front making sure the string still shows thru the back. If you don't you have a 15 minute job trying to fish the wires at an angle thru the insulation (a very frustrating task). Untie the string from the old and tie it securely to the new. Pull the string from the back and Voila! your new sensor can be plugged in or wirer nutted to the old connection on the back of the stove. Replace the nut and the two screws and you're done!

The lower burner would not ignite.
First I removed the oven racks. Then I loosened the two screws in the back of the oven floor and figured out how to remove it. Then I loosened the two screws at the front of the diverter and, with some pushing and pulling and twisting, was able to get that to come out, too. Then I tried lighting the oven and noticed that the igniter was not glowing. When I saw that the upper (broiler) burner was working fine, I hoped that the problem was the lower igniter itself. I checked the wires and they seemed fine. I saw that two bolts held the igniter onto its bracket, so with a socket wrench (which size I got right on the first guess!) I removed those bolts and the igniter came loose. I found the connecter for the wires when I removed the drawer under the oven and was able to pull it apart easily. The igniter came out completely. There was nothing unusual about it, but I decided to take a chance and order a new one, hoping that replacing it would solve the problem. I put the rest of the oven together and waited. About three days later the part arrived (it was sent on a holiday; FedEx is soooo much better than USPS). I retraced the steps of taking the oven apart, put the two bolts into the new igniter to attach it to the bracket, and went back underneath behind the drawer to connect the wires. Then came the moment of truth: I tried turing on the oven. I held the button down to keep the light off, and after a few seconds I saw it: IT GLOWED!! It worked!! After yelling a satisfying "YEAH!!," I turned it off, put back the drawer, the diverter (more pulling and pushing and twisting), and the oven floor. Now it's all working perfectly and it took a very short time to fix. And a little luck that the problem was with such a simple part.

Drum was binding because of worn bearing supporting front of dryer drum
First I unplugged the dryer for safety, then I removed the top of the dryer, then removed the 2 hex head screws holding the font door panel onto the dryer. Then I disconnected the door safety switch. the rest was cake. I removed the old bearing and cut the new bearing and seal to the exact size of the old one. I used contact cement to glue the new bearing and seal into place. Reassembly was a breeze. End of job. Success!!!
