pls i need help on vrv4 ,the compressor was not picking and i check it then i discovered there is no any gas in the system so i presurize the pipe line and i found where the pipe is leaking then i represurize the line to 40 bar after presurizing i vacum the system to 400 micron but now that am charging the system with 410 gas the unit is showing an error code JC and i read the low pressure sensor is ok then i still proceed to change the main panel still showing the same error code,pls help me and tell me what to do ,each time am about to autor charge the system will keep showing JC
In this video . The faulty high pressure sensor reading is Red & Black =K ohm Red & white = K ohm The new parts reading is Red & Black = K ohm Red & White =M ohm
Again nothing learned... ut would help if you tell me factory resistance set point and where does it consider to fail . Low or too high resistance . Anyone can weld teach us the deeper part of these parts that make even uuuuuuu scared
Wow, good job man thanks for video on how to replace HP and LP sensor
Thanks
Hello bom sir where are you from i like also ac work
Do you have to recover the refrigerant before you replace the sensor or it just attaches to the pipe?
Did you replace both, HP & LP switches? Good job Bon 👍
Yes
During replacement of sensor u release all gas from system or only outdoor unit gas, ?????
Outdoor only
Hi, do you have to recover the refrigerant for a hug high pressure sensor. I have here a Reyq72pbtj please let me know I’m hoping I won’t.
Thanks a lot sir
Thanks
Nice video
Thanks
老师烧pipe好帅(⊙o⊙)!!
谢谢😁😁
i also encountered same problem but the error sir bon is not E3 but rather JA-07 VRV 4.
Hope my diagnosis is correct
Should be same problem.
Sir I am from Nepal and I am HVAC mechanic in vrv x7 there is E2 error in outdoor and indoor remote Also what's the problem
Check high pressure switch and high pressure sensor
Sir where is the refrigerant? You pump out in indoor side or recover in recovery cylinder?
Indoor side
@@BonMj sir how to pump out refrigerant please make a 1 video thank you.
How do you pump out to indoor side? Is it by shutting the suction valve until 0 psi at liquid valve?
Hello Sir need to let go all the gas? Before we replace high pressure sensor
Lock the valve,keep in the piping.
@@BonMj pump down system right
Thanks
Thank you sir how to sets back the settings
What setting you mean
Sir please make 1 video for how to vacuum vrv all system
Sure

You this video.
Replace standard compressor 2

Check low pressure sensor
Sir for high-pressure sensor and low pressure sensor what is the normal resistance value?
The simple method is measure .
Red and Black is K ohm .
Red and white is M ohm.
@@BonMj any absolutevalue???
I need to find service manual.
In this video .
The faulty high pressure sensor reading is
Red & Black =K ohm
Red & white = K ohm
The new parts reading is
Red & Black = K ohm
Red & White =M ohm
@@BonMj thanks for responding.....
i have daikin vrv r22 i have error code JA how i can fix it ?
Boss how many ohm is normal thank you
Mega ohm is normal.
K ohms is faulty
@@BonMj what do you mean sir
In this video the high pressure sensor that i measure is faulty.
@@BonMj ok sir for hi pressure sensor what is the normal reading
Daikin vrv x error L4 how to solve
Check inverter pcb
Error uh vrv 3
Check transmission wire connections or pcb faulty
Sub title English can... Next please add to sub titles...
Sir, you have release the gas
Refrigerant recovery
@@BonMj , sir how we recovery if one outdoor unit
You need recovery tank and pump
@@BonMj thanks sir
@@BonMj but I have confused what pump mean
Daikin app is all u nerf
Need
Again nothing learned... ut would help if you tell me factory resistance set point and where does it consider to fail . Low or too high resistance .
Anyone can weld teach us the deeper part of these parts that make even uuuuuuu scared
Next time i will share more details in my video.
