When you installed a new actuator did you do a recalibrate process . If no it could be why they are not lasting . It may be trying to go past its perimeters and damaging the unit . It has to learn the limits . It is odd that 2 has failed . As said above , be sure there is no obstruction .

Just google up a recalibration process and try that first . If no help it mat require another .

I don't know how to eliminate any of the functions but this may help solve the problem .
