I have a Craftsman Model # 139-53985DM Gargae Door Opener. It seems to be on the same frequency as someone else's in the area. When I arrive home each day. it is wide opened. How can I remedy this situation, as I have some valuable items stored in my garage?

Someone may have the same frequency in the neighbourhood.

Check the door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have bad sensors.

It is a different radio frequency and will not work. A new keypad will work.

Sounds like someone else in your neighborhood has the same garage door opener and it's on the same radio frequency as yours. And yours may be opening theirs. Your frequency can be changed, but you'll have consult your Owners Manual on how to do it or contact Sears.

If someone in your family carries the remote garage opener in the pocket or purse, it can be accidentally triggered. I say this, because my mother-in-law used to do it all the time.

There isn't a reset button. Check the house circuit breaker. You may have had a power surge and that can damage the logic board printed circuit. Check the logic board for missing or burnt traces especially around the small transformer.

No the frequency is not the same and the old opener is billion code and the new opener is Security +.

sounds like condensation in the receiver window of the garage unit rather than the remotes. Try running a hair dryer over the area where the signal is received to get rid of any moisture and try using the remote from across the road or at the drive entrance.to check your success

There have been a few complaints about this on some of the other forums and the seals arn;t all that good

Check to make sure that the garage door is balanced. Sounds like the springs need to be adjusted and the travel limits need to be reset.

Took the side off and blue off the board, and re-connected all the wires and conections. It then started working again.
