20 Most Recent DeLonghi PAC C120 Portable Air Conditioner Questions & Answers


This unit stopped working and displayed the PF code for Probe Failure. I fixed it by removing 6 screws for the panal and 4 screws for the back panal and removing the 5 screws and 1 screw holding the ground wire off the silver box with the circuit board in it then I un plugged the little plug for the 2 probes with the black wires in it and replugged it in and wiggled it several times with the unit pluged in (be carefull not to get shocked I recomend someone with electrical experiance do this for you) the plug must get corroded but this fixed my unit.

Good luck.

All units of that sort come with a hose which goes on the back or the side, if you don't have this unit is useless

If filter does not slide straight up an out, You need a Phillips screwdriver. . 1) take off both sides.6 screws each side, 4 under plastic caps. 2) top back there are 2 screws above the filter need the top of the unit. 3) on the top piece there are 2 screws, 1 on each side. Slide half of top off giving you better access to remove filter. Remember to reassembly in reverse

I would drain the water out of the machine via the plug on the back once the unit is drained turn on, wait a few minutes. If compressor does not come on or comes on and does not cool, you need service beyond diy.

It is actually a pan with a float that when full will stop the unit.
On the back of the unit, bottom, there is a rubber plug. Have a pan ready and I would advise have the unit up on a couple of 2x4s or bricks...I used a short tube and drained it into a baking pan, it is too heavy to get into a bathtub or shower.

Air conditioners and dehumidifiers are closely related. Any air conditioner operating in a humid environment will extract moisture from the air and with an outside or window unit, this collected condensation has an escape path and these are not equipped with a container to hold the collected water .
A stand-alone portable unit does not have any other way to dispose of the condensate other than the internal container . . .and you.
Your unit is not defective, you just have it operating in a high-humidity area.
