Abstract
In one embodiment, an overflow sensor assembly of an HVAC unit includes a sensor mounting bracket that is configured to be coupled to a mounting surface of the HVAC unit such that sensor probes of the overflow sensor assembly are suspended within and extend into a condensate drain pan of the HVAC unit. The sensor probes are defined by a sensor element that is coupled to the sensor mounting bracket and a spring that is coupled to the sensor element. The sensor probes are configured to activate an overflow detection circuit when the sensor probes come in contact with condensate fluid collected in the condensate drain pan prior to the condensate fluid overflowing from the condensate drain pan.
