    The PACL 90 shut down one night with the PF light flashing. Is there a way to override this error or to purchase a new probe and install it myself?

The instruction manual says that "PF" means "Probe Failure", that the probe is damaged.  The solution in the manual says to contact the service centre.

Why does my PAC unit continuously flash PF at random and simultaneous intervals?

Wild guess this is a portable air machine? with a tube out a window? Wild guess, there's a condensate "leak" where it shouldn't be. The tank drain might be blocked for some reason. or level of the machine or coils are dirty in spite of the filter.

Hi I DeLonghi T130ARC model air con and no remote and getting a messgae of PF error does anyone know what this means Andrew

Hello my name is Heath it wil be my pleasure to assist you. The PF usually means there was a power failure and the only thing you can do is turn the power off to the unit unplugg the unit and let it sit for 15-20 minutes and then repower the unit and see if the pf goes away.

Pinguino pacl90 wasn't blowing cold air. Service guy "fixed" it and now won't work. PF error code coming up. Help please

Sounds like you may have a coolant issue. If its leaking you can "fix" it by filling up the coolant but it is only temporary. Ask for a leak search or for them to put some leak sealant into the system as a possible correction, no guarantees it will stop it but its better than just filling it up and waiting on it to leak out again.

Error code F1 displayed on unit

We had the exact problem with our unit at work. What we did was turned the unit off at the panel and grounded L1A (or B depending on which fan is displaying the error code) at the condenser and then verified that L1 was grounded at the air handler. In our case it was not, so we rolled L1A and L2S at the condenser. This fixed the error code on our units. Evidently the units need the same sequencing on the fans that the condenser has.
