Craftsman garage opener does not work, just hums

I have a Craftsman (1/2 hp) about 6 years old. It just stopped opening the garage door. I released the release latch and pressed the remote, it moved to open position. But, after that, everytime I press the remote button, it just hums. I checked the chain and it does not jam. I also checked the plastic white gear. It looks like new. I removed the chain and pressed the button, the motor does not run and it just hums. I do not know what else I should check before I go to buy a new opener. Thank you.
