I installed 3 units of the F-MY143 ceiling fans in End 2008. My problem with 2 units.
unit 1 in my living room: When I press the timer off from my remote control, the LED light will show on the fan with beep sound. But after a few seconds, the LED lights will be off. And the timer will be reset. And then, I can't use the remote control to off the fan, even I can hear the beeping sound.

Unit 2 in my master room, when it turn for a few hours, I can hear the fan will produce some noise, like not turning "balance".

Pls advise and help.
