My 'navigator B' switch has developed a problem.  It will only spring return to the center position in one direction.  In other words the return spring only works in one direction.  So if I don't manually return the switch to exact neutral the 110 will keep scrolling through what ever measurement it is suppose to adjust.  Then if I just bump the unit it starts scrolling again. 

Any suggestions how to fix the problem?

Hello Dave,


You can try cleaning the switch first with isopropyl alcohol applied with a brush.

But if the spring is damaged, you will need to replace the switch. In the following link there is a guide to replace this switch:
