George C Golden , CO July 29, 2017 Appliance: General Electric Electric Dryer DBXR453EA0WW Ge Dryer Dbxr453ea0ww: Heater element insulator support broke causing element to short to frame this caused only part of the element to heat and it would stay on when the dryer door was opened. How to replace Idler Pulley. Installed new heater restring kit, WE11X10007. Took maybe 1.5 hours to get the new coils fed through the insulators and get the dryer back together (with help of youtube videos). The heater assembly has 11 insulator brackets, but the kit only includes six replacements. This was disappointing as: -the reason I ordered the kit was that I had a bracket that was brittle and broken and, -this kit is the only way to get the brackets and, -I wanted to replace all of the brackets as some more looked brittle. So, I had to settle for replacing the brackets that looked the most dark and brittle. I hope I picked the right ones. Also, the belt tensioner pulley sides fell off when I took the dryer apart, so I had to replace that as well. It's working well now. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
