Question about liftmaster Chamberlain Garage Door Opener Transmitter 300MC
Garage door will open from remote or car; however, it will not close using these controls. The only way I can close the garage door is to press on the manual control inside the garage until it is completely close; otherwise, it will stop as soon as I quit pressing. It is the Chamberlain Liftmaster Professional Formula I model.
Check the safety photocells is theres not obstacle between then, check both photecells leds are on.. otherwise no need to replace them

Try reprograming the opener to each remote, if this doesn't work then the command/radio module in the opener is damaged and needs to be replaced. Hopefully you can find one or you will have to replace the whole garage door opener. Good luck.
