GTMS855ED0MC General Electric Dryer - Instructions

The end repair was very simple and took minimal effort. The time and difficulty was all in the testing. I disassembled the dryer and removed the drum and then hard wired each thermo-fuse to determine where the fault was. After test all of those I was stumped. When I opened the door the light would not come on so I assumed it was a power fault closer to the source. However after all of my testing I couldn't find anything wrong. I then removed the light bulb and realized it was burned out which led me to the door switch being the fault. I removed the switch and soldered the three wire together and the dryer started right up! All I had to do was order a new $15 part, unsolder the wires and plug them in. Would have been so much simpler if that light bulb hadn't of been burned out causing me to over think my diagnosis. This was my first major appliance repair and I did it with only the help of the parts diagram provided on the website.

Doing some simple troubleshooting with the volt-ohm meter I determined that the door switch was failed.

The replacement door switch restored the motor circuit keeping my dryer in action.

First unplug dryer to prevent electrical shock. To remove the front of the dryer, open the door in top left and top right corners is a machine screw. They can be removed with a Phillips screw driver. Lift the top slightly and let front fall forward about 6 inches, lift slightly. Two wire will be connected to the switch in the door. remove the wires and squeeze the tabs on both sides of the switch and push it out. Push new switch in to replace old switch and reassemble.

Open the door and removed the part. Installed the new part and started the dryer.

Could tell from the sound it was making that it was related to drum rotation. Searched online videos on how to disassemble this model GE Dryer. The Dryer drum rides on 4 rollers. 2 of the 4 of mine were very noticeably loose and made a similar noise when I spun them by hand. Simply replace the rollers and re-assembled.

I could type out instructions, but it's much simpler to just search for the right video online.

Faulty Door switch. Dryer would heat up so I knew it wasn't thermostat or element related.

Dryer would turn on when you pushed the "on" button, but as soon as you let go, it would turn off. Found the plastic door switch cracked (from slamming door closed). Unplugged the dryer. Unscrewed the two screws inside the top of the door to unfasten the top panel. Took the top panel off. Then unscrewed the two screws on the side to unlatch the front panel. Used plyers to take the 3 wires off the switch and slid the switch through the front of the door. Juat remember where the wires go. Then inserted new switch and connected the wires. Vacuumed out the dryer and reassembled. It took about 20 minutes and was easy! If I can do it, you can!!!

It took a while to diagnose the problem. I finally figured out it was the door switch by pushing it with my finger with the dryer door open and starting the dryer. It would run like that, but the switch was not being pressed in enough by the door. I ordered the switch and I should have been able to replace in about 15 min. But the old switch broke while I was removing it and it fell back inside the unit. So I had to remove the top and the front panel to access the door switch. That's why it took so long. If that had not happened it would have been a much simpler repair.
