This is a common problem of Model: 34788, 34788-I, 34988, AC34788, GE48800 etc.
You need to replace air purge solenoid (Air purge solenoid located on top of the ISV tank, if you open front panel cover then you can see it on top of the tank).
After doing above stapes and your problem still exist then you have to replace PCB relay board. Just claim for warranty (Air purge solenoid and PCB relay board) from where you bought the machine.
Hope this will help to solve your problem, if so please vote for it for farther help! Good luck

There are other items to replace before a PCB board and that is not the way to warranty items

ROBINAIR ACR 2000 READS FAILS HIGH PRESSURE, OUTPUTS DISABLED PRESSURE: HIGH


Typically this means you have sucked a bunch of air into the internal tank, from a vehicle that had a leak perhaps ?. Remove the front cover and locate the internal tank. Close the valve on the center hose connection, remove the hose and open the valve slowly and only partially. You should get a good rush of air (not refrigerant). Try it for about 30 seconds then reset the unit. Repeat if required until unit resets. Once reset the unit will purge its self to the correct pressure.

No rush of air ?, could be a bad high pressure switch, connections on the relay board or a wiring issue. If this doesn't work contact me [email protected]

I have a 2003 Ford Focus and I was told by a mechanic that I have a leak...Is there anyway I could find this leak myself? I'm a single parent and don't really have the money to keep paying this...


You can find any leak yourself if you want to. Get under the car and find where it is dripping below your car. Once you've found the spot on the bottom, start tracing it up as high as it goes. Once you've traced it to the source, then it's just a matter of determining why it's leaking there. Is it a broken or loose hose, is it an old gasket? If there's a lot of fluid and you just can't trace it anywhere, pressure wash the engine top and bottom real good to clean it all off and then monitor it for a couple of days to see where it originates.

Good Luck!

DISPLAY READS HIGH PRESSURE UNIT DISABLED


This is a common problem of Robinair 34700Z / 347002K & 347112K series machine. So don't worry just do the following, with POWER SWITCH OFF: - 1# Open front panel cover and verify the ISV tank is not overfilled. If full, carefully remove refrigerant manually from ISV tank by pressing tank valve. 2# verify if there is high pressure in the ISV tank. Purge excess air from the tank manually. (Open air purge hose from the ISV tank, then carefully press tank valve as needed to blow out excess pressure from the ISV tank)

After doing all above stapes and your problem still exist then replace air purge solenoid (Air purge solenoid located near the ISV tank and fixed with automatic air purge device). Hope this will solve your problem, if so please vote for it for farther help! Good luck

Tire pressure reset will not reset


Labatche822,
The process for resetting your Tire Pressure Monitor (TPM) is below.
Good luck, let me know.
Regards.

To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until
TIRE PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about five
seconds. After five seconds, the display will show
TIRE PRESSURE RESET. If TIRE PRESSURE
RESET does not appear on the display after about
five seconds, see your dealer for service. After you
release the DIC RESET button, TIRE PRESSURE
NORMAL will appear on the display.
The system completes the calibration process during
driving. During the first 10 to 25 miles (15 to 40 km) of
driving, the system will not alert you if a tire is high or
low. After 25 to 100 miles (40 to 160 km), the
system will only alert you about pressure differences of
12 psi (85 kPa) or more. After about 100 miles (160 km)
of driving, the system will alert you if one tire is
10 psi (69 kPa) different from the other three tires.
