    I own 3 of the DeLonghi Pinguino portable air conditioners bought at Lowe's here on Maui about 2 years ago and one of them is consistently displaying the PF error code. I guess this is common and there's nothing cost effective that can fix it, so we'll try another model, I guess...

PAC L90 air conditioner keeps frosting up. The room air intake frosts up completely, blocking all the air.

Air conditioners frost up when there is a lack of air flow. Clean the filter, check if a belt is broken (if any), check that the fan spins freely, check all in ports and out ports for blockage and clean the coils with mild soap and water.

It's actually "Ft", which means "Full Tank".  The instruction manual says to drain the internal safety tank through the drain hoses.
To drain the tank, open the cover on the rear of the appliance. Pull out the 2 drain hoses, take off the caps, and let all the residual water flow out.  When all the water has been drained, place the caps back on the hoses and put the hoses back inside.
It also says you need to clean the filters and let them dry thoroughly before putting them back.
This is also the procedure for "End of Season Operations."
Hope this helps!

Delonghi Pac L90

Hoses for proper connection should have been included with your purchase. Without the hoses the set-up can not be done satisfactory. One is for fresh air supply and the other is the hot air exit hose. These are normally vented out a window. Check with the dealer where you perchased the unit from. If from a private individual contact them.

The probe is located on under the main board low inside the only silver metallic box on the bottom w circuit board under it.Remove cover and immediatly you see a 4 inch black wire connected to the main board tucked under and mounted.Unplug the white connector from board, power on, then carefully plug the white connector back on, turn unit off and back on, you should see all 3 mode lights now on steady , no pf error and it doesnt turn off,and you can change modes and temps.Took an hour to take it part and dig around, mine works fookin great now.
