Abstract
A system and a method of detecting a condensate line blockage in an air conditioning unit includes receiving a call for cooling indication from a thermostat associated with the air conditioning unit and detecting a pattern of a plurality of loss of power (LOP) to the air conditioning unit events, the LOP events caused by a trip of a condensate drain line switch. The method also includes analyzing the detected pattern for at least one of a frequency of LOP events in a predetermined time period and an elapsed time between successive LOP events, and initiating a condensate line blockage alert when the analyzed pattern meets predetermined condensate line blockage criteria.
