What does f1 mean on my air conditioner?

Some air conditioners use an E1 or F1 error as an ambient room temperature error. This means that the temperature sensor may not be working correctly. Some other AC systems use an F1 error to signal that the indoor and outdoor systems are unable to communicate with each other. Check your user manual to confirm what the F1 error means for your system.
