steve3333,
Welcome to the forum!
Weak springs? Pivot points/sliders need lubrication?
Weak magnet on the actuator?
I do understand how frustrating it can be when something that
should work, doesn't.
I'd try a little lubricant on all the pivot points and slide/friction points.
I'd also check that the correct voltage is being fed to the operating track
so your magnetic field actuates the operating mechanism.
