remote control stop working
I have a craftsman 1/2HP garage door opener. Model No. 139.53664SRT2. Recently one of remote control (I have two but I only use one) stopped working. I replaced the battery but was unable to reprogram it. I tried both remote control but neither worked. I have a homelink from my SUV synced with opener too. Homelink at SUV works ok. I can still open/close the garage door from SUV.
Another issue, blocking sensor beam won't turn the light on.
Thanks in advance for any help!
