Hi.
I have problem with my Daikin (C9 error).
What is the value of the thermistor in the device: FCAHG125F?
Thank you for your help!

[@BonMj]

Try to check R1T (for ceiling cassette,air thermistor is seal type,remove the wire clip and measure)
Example temperature 30° is 16k ohm+-
temperature 10° is 40k ohm+-

[@mac0pod]

@@BonMj Thank you very much for your answer.
It was corroded. I replaced it.
I gave a value of 20k (in 25C, it is about 16k in 30C).
The air conditioning started to cool but only for 10-15 minutes. Later, the outdoor unit turns off and the indoor unit only acts as ventilation, no cooling. After disconnecting the power and connecting, the cooling works again for 10-15 minutes and turns off (and the room is still hot).
Heating seems to be working normally.
Do you have a solution?

[@BonMj]

@@mac0pod do you check all thermistor reading.like liquid pipe thermistor or gas pipe thermistor

[@j26a24d]

Hello, we see it as a simple repair, but it is a job that takes several hours and knowing or having the capacity and the original parts to solve the error because it is not working and its replacement. I need you to teach how to solder the pressure switches so as not to damage them in the installation or silver solders the vacuum and recharge the unit with freon new minds because it is not in the video the freon leaks into the atmosphere it is not collected for its new uses another Once it is loaded with new freon and how to load it and know when it is at its normal capacity. Thanks a lot

Before change that sensor, are we need to take out all the gas ?

CU only

[@DwiSeetyawanPKG]

Hello sir, if cut the pipe, no leak refrigerant ?

[@rdenir]

Yes the Refrigerant will leak out..
Anytime you tap into a refrigerant system you would need to reclaim/recover the refrigerant..
This is one of my major gripes with Daikin, just about every other manufacturer uses a 1/4 flare male/female for the pressure switches yet Daikin still have this ridiculous setup which makes you recover all refrigerant before replacing the HP switch..

[@priyeshsingh2507]

Sir Daikin vrv 4 coming error f4-04 please how to solve problem

[@rdenir]

F404 is “First Slave Outdoor Unit Compressor 1 Liquid Compression Error.
This is stating that the system has detected a low discharge superheat across the First Compressor (M1C) of the First Outdoor Unit.
This unit detects this by monitoring both the Suction and Discharge temperature and is triggered when the suction temperature falls below 3degC and the discharge superheat is below 10deg C.
The most common issue that causes this to happen is the outdoor unit having liquid refrigerant flooding back to to it from the indoor units.
This is only an Error Code and will allow the system to continue to run.
