Can’t get humidifier to run.

[Woodmanin]

Nest Thermostat gen 3

wired correctly 

had Hvac service person come to troubleshoot with no solution. 

yet it worked before changing thermostat. 

suggested getting new humidifier. 

tested fan and solenoid and both work. Replaced control board ($150) and no change. 

not sure what to do next.

Do you have a picture of the original thermostat's wiring that you can post?

How is the Nest currently wired?
