Pump turns off when switch set to “low cool”

Hello everyone!

I installed a new BonAire evaporative cooler and I’ve ran into an issue. When I turn the switch to “low cool” the fan spins up but the pump turns off. The pump works fine in “pump only” and “high cool”. I’ve verified all the wiring using a multi meter. Any recommendations on things to check?

Welcome to the forums.

What specific model do you have ?
Is this a remote switch you've wired ?
The selector/mode switch should internally power the pump in all positions except off.
