Abstract
Systems and methods are disclosed that include providing a heating, ventilation, and/or air conditioning (HVAC) system with a temperature sensor validation system that measures the ambient outdoor temperature using a first temperature sensor and the refrigeration coil temperature using a second temperature sensor at a plurality of time intervals following a refrigeration coil defrost procedure. A system controller may implement an algorithm to determine if the first temperature sensor and the second temperature sensor are reliable by comparing the temperature readings from the first temperature sensor and the second temperature sensor taken at the plurality of time intervals following the defrost procedure. The system controller may also implement so-called limp along modes if any temperature sensor is determined unreliable.
