View Full Version : Carrier 19CB Guide Vane Limit Switch

27-03-2015, 09:19 PM
We have 4 Carrier 19CB Chiller units, and are having problems with the guide vane closed limit switch not picking up. Carrier has suggested adding a nut to the end of the bolt threads that actuate the switch.

Has anyone tried this? Does it work consistently? Do you have other fixes you can suggest?

Please advise.
