2 most common issues with the wall station are wires being reversed or touching. Try reversing the connection on the wall station. Simply pressing the lock button does not disengage the lock function. Holding it down for 3-5 seconds is the proper way to turn that function off. If neither work, disconnect wall button and try the transmitter. If it works it is possible to have a faulty wall station. If it worked for a while then stopped there could also be an issue with the circuit board. It is always a good idea to put a surge protector in line with your opener. You can get one designed for openers that protect the low voltage components as well.

Car won't start

A mechanic would check for voltage at the starter, the neutral safety switch, and the key switch. Also check the ground connections.

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

Security light will not work

You must have a three function wall switch. This means in addition to a button that opens and closes the door there are two other buttons on the same wall switch. One is marked LIGHT and the other is marked LOCK.

To have your lights come on automatically when you walk into an open garage you must START with the lights ON. To turn the feature on, turn the lights on manually with the wall switch, then press and hold the LIGHT button for about 10 seconds until the motor unit light bulbs flash. Now, if the light bulbs are on, manually turn them out and then walk out through the open door. The light bulbs should come on.

To disable this feature, start with the light bulbs OFF and everything else is the same.
