Garage opens freely, manually and via opener

Not sure how long it's been happening, but it's an older Craftsman opener (if model # is needed I'll post, but I think this is a general question not specific to the brand/model)..


When we close the garage via the opener, it has a 2 inch gap, and pushing it down manually will close the door completely.. Also, I can pull the door up and open it manually, with no resistance at all, even when the opener is engaged with the trolley (I think I'm using the right terminology)..

Any ideas on what to check before the garage company comes over?

Garage door openers have Open and Close Travel limit adjustments. It sounds like you just need to make an adjustment to the Close Travel limit so it pushes the door further closed. Refer to the garage door opener manual for your particular model opener.

If the garage door has a 2-inch gap when closing with the door opener, you may need to adjust the limit settings on the opener. Consult the manual or contact the manufacturer for specific instructions on how to adjust the limit settings. This should help the door close completely without any gap.
As for manually opening the door without any resistance, it is possible that the door springs or other components may need adjustment or replacement. It is recommended to have a professional garage door technician inspect and service the door to ensure it operates safely and smoothly.

You can check the following things before calling a garage door professional for your Craftsman opener:

• Safety sensors: Clean and check alignment (consult your manual or online resources for adjustment specifics).
  
• Close limit switch: Might be out of adjustment (refer to your manual for adjustment instructions).
  
• Trolley engagement: Verify the proper connection between the trolley and opener track (consult your manual).
