Initial symptoms of a faulty AC controller might include inconsistent temperature regulation or the fan not responding to adjustments. If left unaddressed, the climate control system may cease to function entirely, leading to an uncomfortable and potentially unsafe operating environment. Continued operation without proper climate control can affect operator fatigue and productivity.
Before installing, disconnect the machine's battery to prevent accidental shorts or damage to the electrical system. Ensure all electrical connectors are clean and securely seated.
