What Fo means on a Blueridge
The unit is in its refrigerant-recovery mode, started from the remote, which pumps the charge into the outdoor unit so the line set can be disconnected. The indoor and cooling lamps flash quickly while it runs. Not a fault, but you should not see it unless someone started it.
On this platform, Fo is a status, not a fault: the unit is telling you what it is doing; nothing is wrong.
What to do
You can almost always clear this yourself with the steps below.
- If you did not start it, turn the unit off and on with the remote to exit the mode.
- If a technician is pumping the system down, leave it alone.
When to call a technician
This is not a fault. No technician is needed unless it will not clear.
Which Blueridge units show Fo
This page applies to Blueridge BMKH wall-mount, floor-ceiling and multi-zone (2016 and later) and BMY / BMX S-series single-zone (2023 and later) units on the BMKH series (Gree-built). Blueridge's own documentation lists Fo as "Refrigerant recovery (pump-down) mode", the same definition used across the Gree platform it is built on. If your unit shows a code with a different shape (for example a four-character code, or a plain number), it is from a different table; use the lookup with your exact code.
Where Blueridge shows this code
BMKH series (Gree-built): The code shows on the indoor unit's display in place of the temperature. If the display is off, press the Light button on the remote. Some models also count out the code as indicator blinks. E codes are system protections and faults, F codes are mostly sensor faults, H codes are outdoor and compressor protections, U codes are motor and valve faults, and P codes are power-supply faults.
