Outdoor Fan Motor Error

What it means

This code appears on Fujitsu General split and ducted units on the wired remote or indoor display; older models show it as a number of indicator lamp blinks instead of a number. It means the outdoor board does not detect the outdoor fan motor turning at the commanded speed, so it treats it as stopped or faulty. The unit stops the compressor because the outdoor coil cannot reject heat without the fan. The same number can mean something different on other brands.

Models covered: Fujitsu General (Fujitsu, O General) split and ducted units that show a two-digit error code on the wired remote or indoor display; older models show errors as lamp blink counts instead.
