    System Testing & Troubleshooting Failure Modes When any condition results in the rooftop unit’s inability to perform a normal function, it is said to have entered a failure mode. There are two types of failure modes. An “Analog input out of range” failure mode. This failure mode occurs when a sensing device such as a zone temperature sensor or a humidity sensor begins to transmit information that is outside its allowable range.
