Code Text Description Cause Check Procedure Technical Support Notes 7107 Port Setting Error. SW14 set incorrectly. Too much capacity on a single port.
– R410a maximum is 140
– R407c maximum is 81
Confirm that SW14 is set according to where the unit is piped to on the BC box. Also check the system is addressed correctly, especially if you have a sub BC box.
Make sure SW2 capacity settings are set correctly according to the unit model number.
Use SW1/SW4 dipswitches on the outdoor unit to look at port settings.
