Product review (5 stars): Outstanding Dryer Belt Repair Kit
My 8 year old Sears Kenmore electric dryer (model# 110.62722101) started making squeaking noises when operating. Internet searches identified that the problem was likely due to a worn belt and old idler pulley and it was recommended that these items be replaced with the Whirlpool 4392065 Belt Repair Kit (it comes with the belt, idler pulley, two support rollers, four tri-rings and one metal washer that goes on the left support roller bracket). I found a video on You Tube as well as a better one on repairclinic.com which provided step by step instructions. The package also has instructions but the repairclinic.com video was much more helpful. Amazon offered the best price for the OEM recommended replacement item, and with my Amazon Prime membership, I got it in two days. The first package was missing the support rollers and Amazon rectified that by shipping out a replacement package in one day-nice touch. The parts were easy to replace but I recommemded a second person assist you in holding the dryer drum during the belt removal and reinstallation process as it makes lining up the drum on the back and front panel sections much easier. The most difficult part was removing the old tri-rings (I recommend using a very small flat head screwdriver and prying off the tri-rings at the opening near the inside tips of the triangles. By doing this job myself I saved at least $100-$200 dollars when compared to what Sears wanted to charge me to come and fix the problem.  My dryer runs like new again, no squeaking and the piece of mind that my dryer will last many more years. I highly recommend this product, but make sure you get the product made by Whirpool and not some generic dryer belt repair kit.
