schindler 330a hoistway access from bottom landing

Good day gents,

We have a 330a that travels only 4" in the up direction when hoistway access is activated from the lowest landing. Any ideas?

I've been reading these posts for a few weeks, and I respect the content and experience I see with each post. What a great resource for those in the trade. Thanks in advance for any feedback.

Have you checked your access fuses? How old is the equipment?

2010 or so. fuses were good. turns out the switch was faulty. she's all good now.
