Ronald P Effingham , IL August 21, 2016 Appliance: Model GTDP200EMOWW The timer quit working on my ge dryer and the knob was broken I was totally amazed how easy it was to find the parts on appliance parts.com. The pictures and description showed me exactly what I needed. I ordered the parts at 9:00 pm and they were on my door step 36 hours later. The parts were easy to install and we're back to normal very quickly with a happy wife. Thanks appliancepartspros.com. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
