I ordered two automatic door openers. Love them but one I had to use a further hole to get it to shut the door - the one closest to the door only closed it half way. Now squeaks or you can hear the mechanisms when you open the door. Is this normal?<

Thanks for posting! Sorry to hear you're having trouble. This isn't normal, no. It sounds like the first door needed more pressure, which you fixed by moving the closer rod to another "hole." About the squeaking try some lubricate, like a silicone spray, WD-40, or 3 in 1 oil.
