You need to determine the pressure/vacuum exactly. A gauge to do so
will cost around $100. That and the pressure/vacuum the switch is
designed to operate on and you know where the problem lies.
BTW, they rate the switches in inches wc, not what size paper towel
the tube will hold.
You can't seriously expect to come into a newsgroup of professionals
and get any sort of serious response without providing the information
needed to correctly diagnose the problem. alt.home.repair is the
proper place for group guessing.
