3 ceiling fans, 1 new & now 2 old won't work
I have 2 Emerson ceiling fans with after market, Hunter brand remotes that worked great until recently. I just installed a Harbor Breeze ceiling fan that came with a remote. Now the 2 old fans will not work at all, but the new one works fine. The 2 old ones have pull chains and 4 switches in the remote. The new fan also has the switches, but no pull chains. The 2 old fans had the same code on their remotes and the new fan has a different code.
Any idea what I need to do to get the 2 old fans to start working? Thanks
