Had problem with door not closing giving indication of sensor blockage. Of
course there was nothing physically blocking door sensors. After adjusting
the sensor/emitter source position I was able to get the door working but it
was intermittent. In desperation I tapped the sensor and emitter together
using duct tape and noticed the moisture at that time. I ordered
replacements. The opener was purchased last year and parts are supposed to
be guaranteed for 5 years but that is only of replaced by Sears service.
Our previous opener didn't have this sensor setup and we have no children
around so I'm going without them till I can figure out how to better seal
the new sensor/emitter. Was wondering if anyone else had a similar problem
and what was done?
