E4432B Thumbwheel(****) problem

When adjusting the frequency or amplitude using the **** on our E4432B, the increments stop increasing between the 1 o'clock and 2 o'clock position when turning clockwise.  When turning counterclockwise the increments stop and sometimes increase when it should be decreasing.

I would like to know if I could easily rememdy this by disassembling the front panel and blowing compressed air inside the component or will I need to replace the front panel assembly.

Thanks
