Have you had an electricIan look at them? In many models you can pull out the transponder and replace it with an aftermarket model with a new remote.

• Furn Fan Corporation 5UFO52 Fan
• Owners Manual

Remote receives is wired as shown in Owners Manual section 7 and tucked inside the canopy as shown in section 8.

Id pull the reciever and replace with a new kit that includes a paired remote.

1. Check/replace the batteries in the remotes.
2. If the fans also have wall switches, make sure they're on.
3. Test each remote against all the fans. Set aside any remote that works with a fan.
4. For a remote that doesn't work with any fan, reset the remote and fan code switches to match (see page 7 of Owners Manual). Re-test.
5. If a fan/remote combination won't work, replace the receiver and remote.

Thank you all!!!!
