I was inspecting an air handler in the attic of today’s home. The air handler had a secondary condensation pan with a water detection float device beneath the unit. My shirt sleeve snagged the float device and pulled it. The system did not shut off. My curiosity got the best of me and I raise the float device and the system still did not shut down.
My question is do these floats have to absorb water to shut down the system like a rain sensor on an irrigation system, or was the water float likely not wired properly or defective? Should I make a point to check the the water detection devices on air handlers in attics?
Thanks in advance.
