Overflow circuit not working

eddiemarcano1September 17, 2013

I tried to manually push the overflow switch open and the AC does not turn off. I check the circuit and looks good but for some reason I still getting 24VDC at the thermostat key pad while holding the overflow switch open.
Could the little board (relay) be bad

Thank you for reporting this comment. Undo

Nope. The switch is old school,it's either open ( if pump fails) or closed ( when water level is normal in tank). You either have a defective switch or it has been by-passed.
