Inspected and fund a broken spring laying under the unit. come to find out it is a "counter balance" spring... go figure. the hardest part of the repair was moving the washer around, in order to locate the model number. once we found that, it was all down hill from there. I have used APP.COM for years, and never had a problem. very easy to navigate, fair pricing, and FAST shipping. the part arrived in 2 days, and the repair was finished in a matter of minutes. the only difficulty was locating the correct place where the spring was to be mounted.
