Part # 89309 must match part # of your original receiver. Part # 89309 must match part # of your current receiver (found on sticker as the back as shown in photo). It's compatible with all 89309 receivers.
Saved me buying a new fan. I think the old one absorbed some stray voltage from a nighttime lightning strike. Pretty straight-forward replacement. A helper is good to have but I got it by myself even after dropping 3 screws.
It's exactly like the one that went bad. Wired it up. Works like a champ. There are no instructions so just remove power and change one wire at a time if you need to. Remember to set the dip switches to match the replaced unit so your remote works.
