Jumper Cap Malfunction

What it means

This code appears on Gree split air conditioners when the indoor board does not recognize the jumper cap, a small plug on the board that sets the model and capacity data. Without a valid reading the unit will not run. The jumper role and position vary between Gree series, so check the unit manual. The same code can mean something else on other brands.

Models covered: Gree split (wall-mounted) air conditioners, mainly inverter models; the code shows on the indoor unit display. Older non-inverter models may show fewer codes.
