Abstract
A program product for determining an obstruction in an air circuit for an environmental control unit having a motor is provided. The program product comprises a program and a non-transitory, computer-readable storage medium. The program is configured to at least facilitate obtaining a load current of the motor, determining a state of the motor, generating a comparison, and determining the obstruction using the load current and the comparison. The comparison is generated by comparing the load current to a first plurality of values if the motor is in a steady state, and by comparing the load current to a second plurality of values if the motor is in a transient state. The non-transitory, computer-readable storage medium stores the program.
