Chamberlain model 9950 garage door problems. I have very low range on my remote and built in car remote in my Prius. I have replaced the control module in the opener and the problem is still there. I have turned of my wireless lan network in my house and the problem is still there. I can just barely open the door with the remove next to the metal sectional door closed. even with the door open, the range is only 15 feet. can you help please, before i buy a whole new system and still have the problem. Also , do you know the frequency that the remotes operate on??

I thought I had it but I tried this in cold weather the rubber drive belt will contract making the open think that it is binding or getting stuck so I think it is shutting itself down. I released some of the tension by loosing the nut adjacent to the tension spring. The door started working I will see if it works in the morning.

if it happens to both remotes and the built in system the problem has to be with the reciever in the unit or antenna, where you have this unit is it inside a metal building? if so you may need to move the antenna outside the building.
good luck
please mark the post with a fixya

The motor is probably either stalling because the door is too stiff, or you have a beam break detector that is being triggered when the door is halfway down.

If you have to hold down the button to close the door, you are bypassing the sensors ...
Check the alignment of the sensors. Should see a solid GREEN light
