If you added refrigerant, was the compressor running better before or after you added refrigerant? Compressor cycling on-off can be caused by defective low pressure switch (very rare on Subarus), or low on refrigerant. Best to test with a good refrigerant gauge-- resting pressure (system off) should be between 45 and 80 psi (higher pressure with higher temperature) on the suction side. Make CERTAIN you attach the gauge to the suction side (the side with the larger diameter hose). When the compressor cycles on, if suction pressure drops below approx 23-29 psi, the low pressure switch will shut off compressor to prevent damage. If low suction pressure, cure is to add refrigerant, little at a time. NOTE: Refrigerant is under high pressure, and is very dangerous. If you are not trained to handle refrigerant, suggest take this problem to a shop to check out.

How do you know if your AC compressor is over chaged?
If the unit was freezing the evaporator before you charged it and now you do not have cooling, you may have overcharged it. The best way to determine this is to have a certified AC technician check the actual pressures of the system as most do it yourself cans do not have acurate gauges. The compressor may run constantly, but not cool or the compressor may run and then blow a fuse or the compressor may run and there is no cooling, but the only way to acurately determine an overcharge is to measure the pressure with accurate gauges.
Does the Danby DWC350BLP have thermal electric cooling?
No, the Danby DWC350BLP does not have thermoelectric cooling. It uses a compressor-based cooling system for efficient cooling of your beverages.
Lumina 2003 ac not cooling even when compressor is replaced?
Was unit evacuated before recharge after compressor replacement?
Is it good or bad to have an engine running with the air conditioning lines unhooked if there is no freon in the cooling system?
If the compressor is not engauged, it is ok.If the compressor is not engauged, it is ok.
Why does an air conditioner need a compressor?
The compressor is needed for the cooling of the air. This works the same way the compressor of a fridge or a freezer work. It uses the physical principle of a heat pump.
Can the engine cooling fans not working cause the compressor to mess up?
no they cant
What could be the cause of an air conditioner in a 1999 ford escort not cooling but still blowing coolant levels have been checked and are high enough everything under hood was checked and seemed ok?
Was the voltage to the compressor clutch checked? Not knowing how thorough the under-hood check was, it sounds as if the compressor is not engaging. The causes for that are varied, but it is an electronically controlled event.
What does the compressor on a heat pump do in heat mode?
The exact same thing it does in the cooling mode, the change between modes of operation does not take place in the compressor.
Where is the capacitor located on an outside ac unit?
near the compressor on the wall of the cooling condenser
Excess superheat means the compressor inlet is warmer and evaporative cooling is?
Subcooled
Why does the air conditioner on my Saturn Vue stop cooling when the car isn't in motion?
compressor is two stage and the 1st stage has gone out and the compressor needs to be replaced.
Can a ac accumulator cause a cooling malfunction?
There is no such thing as and air-conditioner accumulator in an automobile. A nonworking air-conditioner compressor can cause a cooling malfunction.
