What to do if a check code is displayed on the Carrier RBM-Y0613FUL remote controller?

If a check code appears on your Carrier Air Conditioner's remote controller, it could be due to several reasons: * The outdoor power might be off, so verify that the header outdoor unit power is on. * There might be an address setup error. In this case, set up the address again. * There might be no outdoor terminal resistance, or more than one resistance. Check SW30 bit 2 of the header unit. * Communication between outdoor units might have stopped. Check the number of connected outdoor units and ensure that outdoor unit power is on. * The number or capacity of connected indoor units might have been exceeded. Adjust the number or capacity of connected indoor units.
