Greetings all, a troubleshooting saga.

Having finally cleared access, we replaced the ceiling fans in the
kitchen and living room. To compound issues, these were on sale at
Costco, and sat in their boxes for three years. So I'm not sure that
warranty is an option.

They being the New And Improved Modern model, it has a Remote
Control. Which is wonderful. No more old fashioned pull chains to
turn the lights on and off, or change fan speeds. Oh, and did I
mention the lights are on a dimmer control? Very nice. (Of course,
the bulbs supplied were Curly CFLs which were not dimable. And are
stuck now at a mid-level.) The living room installation went as
advertised.

We managed to get the 2nd remote and the kitchen fan "paired".
Once.
Now, the Remote Control doesn't control. The Procedure is to shut
off power at the wall switch off for two minutes, and within two
minutes of turning the power back on, push and hold the off button on
the remote. It will blink to show you have made contact. If it
doesn't change the dip switches. There are 4 switches ("Do not use 1 2
3 4 - on" says the instructions) plus a Dimmer on / off -for 32
options, at 4 minutes to test each settings. Not what I wanted to do
on a sunny day..

The annoying part is that the other fan / remote in the next room
set up and initiated as advertised. It even ran the one in the
kitchen. Neat trick, but not useful.

I think these are radio remotes, as the instructions mention
"antenna" in the receiver, so not sure what kind of app might be
available. Anyway, any suggestions for how to test if a remote is
sending a signal?
And test if the receiver is getting any signal?

Should I attempt to just splice leads into the fan, hardwiring to
a wall mount controller? Give up and put the old one back? It was
working. (The living room fan had the reverse direction switch fail.
Replacement parts could be had for 50 cents if I bought five
thousand.)

Nuke them from orbit?

use incandescent lamps - no dimmer or on full - see what happens. Some
CF and LED bulbs and some dimmers interfere with the RF remotes.
