GTDP740ED1WW General Electric Dryer - Instructions

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.

There is a plastic female closure part in the dryer door that wouldn't close tightly around the metal male closure on the dryer. I popped out the plastic square with a screwdriver, popped the new plastic closure in with my thumb. Works great. I never even installed the new metal portion of the latch.

Simply popped the old broken part out and popped the new part into place. I wasn't sure if it was the Latch Door or the Door Strike. Once the parts arrived, it was clear the Door Strike was not the issue.
