Overhead door model 456 odd operation

After some time with the light not working correctly, our model 456 Overhead
Door opener started to randomly open & close. Generally only 6 to 12 inches of movement. I confirmed no stuck remote or wall switch buttons. Operation with
remote results in only partial movement too. Tried unplugging for a while, no
change. Is the circuit board the most likely problem? Are they still available?

The best thing to do is to call the manufacturer.
