SOURCE: delonghi pac-02 a/c

I had similar problem .... on very humid days unit leaks ..... temp solution for me was to drain the unit .... inserted wire coat hanger into tube .... lots of watery gook came out.. - even tilted/tipped the unit inorder to get as much water out of it.......afterwards unit worked fine.

We are VERY SASTIFIED with the Delonghi Pinguino - bought it years ago when it first came out and it has provided years of troublefree service .... the water build up / leaking was only recently - in fact we never drained the thing until this year.

SOURCE: DeLonghi Pinguino PAC CT90 It is less than a year has quit coolin

Read instructions and see if it says anything about cleaning or filters. A.C units **** air in and there is a filter that probably needs cleaned.Also,while cooling, the vent to the outside should put out warm air. Also, if it is less than a year old, contact the manufacturer and they should help you out. Good luck.

Delonghi PAC a120e ,why is it leaking and also is ther a filter

Don't know if this is the type issue you are having. I had my unit leak all over the place last year and found there was ice buildup on the inside of the unit. You would have to remove the cover completely in order to check this out. Also make sure the drain is clear.

Sorry I do not speak English well. C120 pac my team. PF mark on the screen and turn on all lights. not working I have to do Thanks for your time

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.

Laptop can't power on without battery. but plugged in

Try this. With the battery removed.
  • Plug in the AC.
  • Will pressing the power button repeatedly gently wiggle the AC adapter
If it powers on briefly then your DC jack inside the computer will need to be replaced or re-soldered.
If if doesn't power on at all get or borrow a multi-meter and set it for 20+V. With the AC adapter plugged into the wall and unplugged from the PC touch one probe to the outer metal on the part that plugs into the laptop and one probe down the center of the plug. If the probe doesn't go in all the way stick a paper clip down the center (dont let it touch the outer metal) and touch the probe to that. Ignore if the voltage reading is negative or not this just means the probes are reversed and doesn't matter really if you get a reading +-1 volt from what is listed on the AC brick. If you get nothing or it is very low then the AC adapter needs to be replaced.
If the AC is fine. Then it could be the fuse on the motherboard. In that event easiest route would be to replace the motherboard (don't think you can buy the fuses)
Comment back if you need more assistance.
