What EE means on a Friedrich
A control board (indoor or outdoor) could not read its stored parameters.
On this platform, EE is a fault: something has failed or is disconnected and needs diagnosis.
Common causes
- A surge or lightning event.
- A failed board.
- A replacement board not programmed for the model.
How to fix it yourself
Do the reset and the visual checks, but the underlying repair needs a technician with a meter and the service manual.
- Reset the system: switch the breaker (or the outdoor disconnect) off, wait a full five minutes so the boards fully discharge, then switch it back on and restart from the remote.
- If the code comes straight back after a reset, the fault is real and not a glitch.
Switch off power at the breaker before opening either unit. Capacitors in the outdoor unit hold a charge for several minutes after power is cut.
When to call a technician
If a reset does not clear it, the board needs replacement or reprogramming by a technician.
Which Friedrich units show EE
This page applies to Friedrich Floating Air Select (FSHW / FSHSW, 2015-2019), Floating Air Pro and Floating Air Premier units. Friedrich's own documentation lists EE as "EEPROM (memory) error on a control board", 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 Friedrich shows this code
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.

Questions people ask
Can I reset a Friedrich EE code myself?
Yes. Turn the system off at the breaker for five minutes, then restart it. If EE comes back, the fault is real and needs the checks above.
Is it safe to keep running a Friedrich showing EE?
The unit will usually refuse to run, or run with reduced output, until the fault is cleared. Repeated resets do not fix anything and can mask a problem that is getting worse.
What will a technician check for EE?
If a reset does not clear it, the board needs replacement or reprogramming by a technician. Ask for the measurements, not just a parts quote.
