My garage door is open and close improperly especially when it is cold in the morning. Sometimes it will not open and not close, command to close by the remote and it come down a few inches then come right up. The photo sensors and them seem to be OK. Are the sensors going bad or some loose wires. If someone know this problem, please help me to lighten up about this issue.

Greatly appreciate,

Thanks,

Hello Cuong

Start with checking mechanically all components involved.
I everything is fine in this respect, than follow up with testing the wired electrical system.
Is there some hardwired electrical control panel? If so test that.
Last test the remote controlled system.

There are too many possible causes to give you a solution to your problem, so please post here the outcome of your inspection, if possible in the sequence I posted here, as that follows a logical test sequence.

Success!
