What to do if my Harbor Breeze 40821 remote doesn’t work?

If the LED indicator doesn't illuminate when you press a button on the remote, replace the remote battery with a new 12-volt battery. If the remote is not synced with the fan’s receiver, turn off the main power, then turn it back on. Within 30 seconds, press and hold the high and low speed buttons on the remote at the same time for 5 seconds. The LED indicator will flash 3 times, signaling a successful synchronization. Once complete, the fan will start on the low speed with the light off.
