How Do I Disable The Entrapment Sensor On A Csl24u?

I have a CSL24U running exclusively on Solar / batteries. I have the entrapment sensor bypassed by taping the reflector to the transceiver. This was necessary, as any precipitation whatsoever caused the system to fail and gate not open. It permanently displays a 93 (entrapment sensor) error now and opens when it feels like it - which is rarely. It is common for it to open 6" with each remote activation. Sometimes it is more like 12". Other times as much as 18".When it does this it also exhibits the characteristic of starting the gate motion at full speed instead of slowly accelerating as is normal.Then other times it opens normally. It will also exhibit all these characteristics when closing sometimes. The colder it is, the more likely it is to fail. We even have a warmer wrapped around the batteries to keep the temperature up, therefore the voltage, as this thing won't function if it's even .5 volt below 24 vdc.Also, yes, I have upgraded the batteries. Two 35VA batteries in series and the system continuously displays overcurrent (code 41).I hate this thing and Liftmaster is no help as they say it wasn't installed by one of their certified installers. It's just over a year old and has done this since DAY ONE.
