Customer Question

Have a question about a Fujitsu multi zone error code
Submitted: 1 year ago.
Category: HVAC
Customer: replied 1 year ago.
The code is on the outdoor unit "E2 21"
Indoor capacity error.
What does that mean?
Expert:  BillyHvac replied 1 year ago.


the indoor board and outdoor board have to recognize each other. This code means the outdoor board no longer recognizes the indoor board. This means the outdoor board is bad.
