    where is the pressure transducer on this machine?

  • Kevin Jay Friesen May 22, 2014

    The Pressure transducer is on top of the block in the back of the machine. there are 2 transducers, the lower one is the accumulator transducer and the higher one is the Pressure transducer.

We have a robinair 34788 and it wont recover

Does it flash any codes on the screen when you attempt to recover? You'll want to check the inline filter as well as the condition of the pump oil.

Robinair 34788 will not charge properly

I would be very careful releasing refrigerant from the liquid side of the tank as suggested earlier. Knowingly releasing R134 into the atmosphere carries very large fines if you get caught and is very environmentally irresponsible.

HELLO I HAVE A ROBINAIR 34788, MY UNIT WILL NOT CLEAR THE LINES. I TRIED SHUTTING OFF AND ON , BUT LINES ARE STILL HOLDING PRESSURE. I ALSO CANT RECOVER BECAUSE IT WILL NOT GET PAST CLEARING. THANK YOU

sounds like you need to check the grommet between the motor and the pump. If this grommet connector breaks, the motor will come on but the pump will not work. Turn the unit upside down and look where the motor connects to the pump. Be aware if you can lose your oil while turning upside down unless you cap the port and exhaust. If this is it, go straight to the Robinair web site and you can order one for around $25.

I have a robinair 34788 machine and when I am recovering a system for service the recover feature no longer completes down to the oil drain. Its like it gets stuck on recover.... and by that I mean it...

It's sound like problem with oil drain solenoid or harness. please check harness of oil drain solenoid. If harness is ok & connected with relay board then you need to replace oil drain solenoid.

I'm in afghan and I have a robin air cool tech 34788. It's take a long time to the clear the line and and a long time to recover plz help me out

I think your machine is working normal! Robiaair 34788 is high bred technology machine, you can't forse on it to fast recover! It will compleate the process it self. However if you still think this is not working normal you can check low/high side hose & coupler for any block.
Hope this will be helpfull to you. Good luck
