I have an adventurer 37f with the power operated bed that allows you to raise the head end for reading or watching tv. It must be fully raised in order to retract the slide. There is a lippert control module at the foot of the bed enclosed with the fuse center. The bed will only raise a few inches and then the motor stops. The lippert control modules has led lights flashing which did not flash prior to this problem raising or lowering the bed. Any thoughts on how to remedy this problem will be greatly appreciated, Thank you.
