How to fix and repair PF Code on a Delonghi PAC C120E Portable Air Conditioner. It has been a great machine for me, running constantly for years, but it finally quit with a 'PF Code'...which means 'Probe Failure'. To fix it, I replaced 'the feeler'. I'll show you every step I took to open the case, remove and replace 'the feeler' and reassemble the case. It was much easier than I thought it would be, but still took me a couple of hours because I had never done it, and had to learn by doing...while recording a video (another 1st for me).
If I can do it, YOU certainly can do it. This is the video I wish I could have found to help me before I started. If I ever need it again, now I've got it...and so do you. Please let me know if it helps you.
UPDATE: August 3rd, 2023: I originally ordered 'the feeler' replacement from [ Ссылка ] -$8.89 and it's currently 'out of stock,...and it appears to be out of stock everywhere. If I find it available anywhere, I'll delete this sentence and post the links.
MEANWHILE, a commenter below posted that a similar part from another sensor can often work just fine, but to make sure it's a 5K Sensor.
