Easy Bathroom fan replacement
I received the parts for the bathroom fan overhaul. They were the exact part numbers that were needed to perform the job as well as some instructions that came with it. It took about five minutes to replace the motor in about 30 minutes to get the fan part off to put on the new motor. Overall much easier than replacing with an entire assembly.

Perfect replacement, perfect fit.
I was really pleased to locate the exact replacement motor for my forty-year-old bathroom fan. The unusual round shape of the fan unit would have made changing the whole unit difficult. After installation, I realized my old motor was hardly moving air at all. My fan now works great.

From an Untrained Novice
The part came quickly, wish it had more packing material around it, but all seemed fine. Also wish it had install instructions, but with the help of some YouTube videos of other similar installs was able to see how the green wire (ground?) should be attached as my old one didn't have one. Works well, a bit noisy, but I suspect it's more the blower wheel, or the fixture being so old or getting used to the quiet of being without a fan for awhile. Should've taken photos before I removed the old one first to ensure I put it all back properly. So in the end, I'm satisfied and I met my goal of saving money by not hiring a handyman. I would order from this company again.

I found that although it was extremely old and filthy I was easily able to remove all parts to find that it still had a model number attached on a sticker. I went to eReplacement parts and quickly and easily found a replacement motor. Although a bit pricey, I felt worth the investment. Received the motor quickly, and after cleaning up the other parts, installed the new motor on the motor clamp and mount assembly. Then realized that I needed the fan cover as well as a tiny fitting was needed and missing from the original. I then looked that part up, and ordered. Needless to say all is working well, and I appreciate eReplacement parts !!!!!
