Your receiver has failed. The hardwired wall control doesn't use the receiver but the remote and the keypad do.

I have a 1/2 hp craftsman opener. Remotes work fine. Wired wall unit has a blinking light on the open button and will not work Lock pad and light pad work but not the operate pad.????


Try pressing and holding the lock button for 3 seconds to stop the light from blinking. Your wall control may be bad. Usually when that light is blinking it is the remotes that will not work.

Intermittent remote trouble


Your wall control is hard wired and doesn't use the receiver portion of the logic board. The remotes do. Your receiver is going bad.

NEED TO CHANGE PASSWORD ON KEYPAD


If it is a wireless keypad you need to locate the smart/learn button which is near where all those white wires go. Press and hold this for 6 seconds. This will erase the memory and none of your remotes or keypad will work.

For the keypad: Press and immediately release the smart/learn button and walk over and key in any 4 digit PIN you like and press enter.

For your remotes: Hold down the button on your remote and then press and immediately release the smart/learn button. Do this for each remote.

Craftsman 1/2 HP Garage Door opener problem


The remote and the keypad work through a signal sent to the receiver while the wall console, as you said it's wired directly to the opener, so it's likely that the receiver is shot. I'd try reprogramming the remote to just rule out the chance that all code wasn't erased first. (Press the learn button on the back of the operator head, stand back 5 feet and within 30 seconds slowly press the remote button a few times to see if it operates the opener). If this doesn't work, you can install an external LiftMaster universal receiver with the correct frequency and you should be good.
If there's a purple antenna hanging off the head, this is a 315 freq, use a 356LM, if black it's a 390 freq, use a 635LM receiver.
Then you'll have to reprogram your remote and keypad to the receiver.
Since there's also the issue with the light, there's also a possibility the circuit board got fried. Did you have any storms lately?
