Abstract
A system and method of determining a limit fault in an HVAC unit the HVAC unit in electrical communication with an HVAC system controller, by operating the system controller to determine whether an interruption duration of time exceeds an interruption limit, operating the system controller to determine whether a cycle duration of time is less than or equal to a first cycle limit, wherein the cycle duration of time is indicative of an amount of time between consecutive interruptions of power, and generating an alert signal if the interruption duration of time of the consecutive interruptions of power exceeds the interruption limit and the cycle duration of time is less than or equal to the first cycle limit.
