1. A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
a compressor;
a fan;
an inverter configured to drive operation of the compressor; and
a controller communicatively coupled to the fan and the inverter, wherein the controller comprises a tangible, non-transitory, computer-readable medium with computer-executable instructions that, when executed by processor circuitry, are configured to cause the processor circuitry to:
determine an operating parameter of the fan in response to an interruption in receiving communication signals from the inverter; and
operate the fan based on the operating parameter during the interruption.
