Most of the time an algae growth is the culprit blocking the drain.

Hvac safety switch location.

Prevent dangerous mold growth. What it does it gives your ac system the ability to detect if it has a clogged drain and if the switch detects a clogged drain scenario it immediately shuts the system off. When ac units run they create condensation which is removed from the unit through a drain line. Most people know that air conditioning units cool indoor spaces by removing heat from the air but what many people don t realize is that in this process air conditioners also act as a dehumidifier and remove moisture from the air.

Have you figured out an a c problem without calling an hvac service. If the air handler s float switch has tripped the primary condensate drain has stopped up due to a blockage and the blocked water has tripped the float on the float switch.
