This will cause the head pressure to climb very high and if something doesn't explode or cut out on a high pressure safety, you and the equipment will be damaged. Hopefully compressor will be one with internal or external overload. To summarize DONT DO IT WHILE COMPRESSOR IS RUNNING.
the discharge service valve is closed.
If the hose is hooked to the compressor discharge it can cause it to blow up. It should be hooked to the liquid line.
Check the capacitor located inside the outside condensing unit,usually the fan,compressor are wired together,if one is running the other should be running
If the clutch disengages properly then the compressor should not be running. Most likely the clutch itself is bad instead of the compressor.
even though your compressor is still running does not mean anything... what you need to do is find out what refrigerant this vehicle calls for either R-12 or R-134a and have a a/c recharge service done and then you should have ICE cold a/c
You can hear it running. Unplug the fridge, then wait approx 1 minute and plug it back in; you should hear it kick on.
You have a cycling clutch compressor. Turn the AC on max, let the car for five minutes or so, go look at the compressor. You should see the clutch engaging and disengaging the compressor as the pressure builds and drops.
Yes, in order for the compressor to take on the new coolant and oil charge the compressor ideally should be running. It is posiible to begin charging the system with freon prior to compressor initiation, however to get an accurate reading of the pressure in the system the compressor should be cycling with differential valve operating properly. If it is clogged or the compressor is not cycling then then low side reading will give an elevated pressure while charging the system. Does that make sense?
You don't.Suction temperature does.Suction line should be cold and sweating.That's what keeps compressor motor cool.Discharge will always be hot.
These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.
The ampmeter should show a discharge with key on, engine off.
Check your discharge papers. You should have been issued a DD214 upon discharge. It will list all of your awards as well as your unit history and dates of service. You can contact the appropriate service if you cannot locate yours.
