Re: Grunaire F1 error code
Swap board from good unit to one with fault code, if code goes, new board faulty.
If code stays look for another problem.
We don't get that make over here, what is an f1 code for?

Re: Grunaire F1 error code
Just got the same code. F1. Did you ever figure it out? Checked all the connections to the unit. Is there a reading or easy way to figure out if its the PCB board? There seems to be 3 boards which one is the PCB? I have a spare unit so can exchange parts pretty easily. Thanks.

Re: Grunaire F1 error code
F1 usally means the main boards in the outside unit is bad.
Amcor units were notorious for F1 outside PC board failures. Grunaire is made by the same company.

Re: Grunaire F1 error code
Meant to say, it is the main pc board in the outside unit that likely burned out.
