Product review (5 stars): Dryer Belt Tension Pulley Idler
This pulley was the correct part for our Maytag MDE3706AYW. It wasn't eligible for Amazon Prime but it was still delivered within 3 days. I ordered it on a Saturday evening (after an unsuccessful trip to the local appliance store) and received it the following Tuesday. Replacement was a breeze. Our dryer has been repaired for over 1 month now with no problems.
