Top 20 DeLonghi PAC C120 Portable Air Conditioner Questions & Answers

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.

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

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.

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

DeLonghi has the manuals for their portable air conditioners here: http://delonghiusa.com/support/product_manuals/5#table-jump . The direct link to the PAC C120 manual is http://delonghiusa.com/support/sites/default/files/product_manuals/m-PAC+C120.pdf .

Before cleaning, turn off the air conditioner. To clean the filter, pull it straight up from behind the top of the air intake (on the back of the PAC C120). Vacuum off the filter. If it is very dirty, immerse it in warm water and rinse several times. (The water should not above 40 degrees Celsius (104 degrees F)) several times. Then allow the filter to air dry. Slide the filter back into the air conditioner and turn the unit back on.

I hope this helps.

It sounds as if the drain plug on the back of the unit, down near floor level is loose or missing
Check for that first, because the unit is supposed to shut off automatically, when the drain pan is full. If the plug is leaking or missing, the unit doesn't sense, that the drain pan is full. Also, be sure you exhaust ducts are not bowing down a great deal or trapping exhausted moisture in the duct, that should be exhausted out the window.

Hope this helped you to troubleshoot and solve the problem.

Remove the tank if it is removable and see if you can determine how it is sensing the tank level. Maybe it's a float switch that is stuck or maybe it works by the weight of the tank. Either way your problem will be with whatever senses the tank level.

See this manual. It is of Delonghi HM25E type 061567T. It may help you. DELONGHI HM25E ELECTRIC HEATER IMPORTANT INSTRUCTIONS MANUAL ' ManualsLib

Question edited for clarity. It probably needs a top up of refrigerant gas. Take it into a local refrigeration company.

That means that the switch is broken and is passing power when supposedly off. Claim on warranty, it is dangerous. If they say no, ask if there are any Class Action Lawsuits on it yet? https://www.delonghi.com/en-us/customer-service/warranty ..

So, it sounds like your Delonghi hifi heater is giving you some trouble, man. The constant beeping and the green light on the control board, it's like it's trying to tell you something. My guess is that there's something funky going on with the thermostat. The beeping is probably the heater's way of saying it can't maintain the desired temperature because the thermostat isn't working properly. And the green light, it's like the heater is still getting power and trying to do its thing, but the thermostat is holding it back. One thing you could try is checking the thermostat settings and making sure they're all good to go. If the settings are chill, but the problem persists, it might be time for a new thermostat. You could also try unplugging the heater for a bit and then plugging it back in, see if that helps reset the system. If all else fails, it's best to reach out to Delonghi's customer service or maybe even a professional technician to take a look and give it a tune-up. It's not always easy to fix these things ourselves, so don't be afraid to ask for help.

:To open the case of a DeLonghi model PACAN125HPEC, locate the screws on the back of the unit and remove them. Once the screws are removed, carefully lift the back panel, being careful not to damage any of the internal components. The case should then open and you can access the internal components.

Question edited for clarity, full 'make model (what it is)'. Question moved to correct category. You have done everything you can do. Take it to a DeLonghi service centre or to a refrigeration engineer. The buzzing is likely the compressor and needs a new start / run capacitor. https://www.google.com/search?q=delonghi+pacn130hpe+portable+AC+buzzing+noise ..
