35 to 40 psi would be normal. If you are not cooling well you may have a bad compressor.

If you charged the unit yourself the only thing I can think of is that you did not charge it properly. Refrigerators are not like AC units - the amount of charge, measured in ounces is very critical. You have to be right on the money lest it not cool properly.

If you have access to gauges and you are using the AC refrigerant normally used for cars, the pressure at ambient room temperature of 78 degrees should be around zero. Let the unit run for about thirty minutes to stabilize pressures and then do the reading. If room temp is higher than 78, then pressure can be a tad higher but no more than oupounds.

If no gauges, then allow unit to stabilize and then observe the temperature and condition of the suction line to the compressor. On a properly functioning unit the line should be cold to the touch and maybe sweating or beading. If it is warm to the touch you are low on refrigerant - add small amounts slowly till pipe cools. If you have frost forming on the pipe going to compressor the unit is overfilled and you have to bleed it slowly till it is cold and wet, not covered with frost.

Insufficient cooling is also caused by a improperly working freezer defrost mechanism whereby ice accumulates in freezer compartment. Here the culprit is either the defrost timer and or defrost heater element.

When you change from heat to air , it still blowes hot air like it is not switching to air conditing, the compressure is running and lines get cold, but no cold air. thanks


If the orifice filter is clogged, this will happen, a better check can

be done with an ac manifold gauge set, the low side reads the

evaporator pressure and the high side reads the discharge

pressure. I had the same problem while checking the ac on a

2000 gmc 1500 z71 4x4. other things that could cause this are

to much oil in the ac compressor or not enough freon in the

system. an overcharged system , the best way to check it is with

a gauge that way you can tell if you have the right amount of freon

and oil in the system. plus the gauge set will let you know the

extent of your problem. good luck!

2005 terraza never gete cold enough. in hot


It is hard to diagnose the problem with out knowing readings on the ac system,a low and high pressure readings would need to be known.This is needed to know if it is a internal ac system problem,or a vent door,or temp door problem.Have a mechanic put a set of gauges on the ac system to determine what is going on with the system.

What are the readings on your A/C service gauges, hi and low sides? If you don't have service gauges, inexpensive ones can be purchased at stores like: Harbor Freight, Walmart, Pep Boys, etc. The gauge readings are the first step to a correct diagnosis.

Your system may be low on refrigerant. If you also have a rear heating unit, the air mixing door or water valve may not be shutting off. Your expansion valve may be bad in the rear unit.

If you can access your rear a/c, check to see if the inlet hose is hot or cold. If it is cold, you are low on refrigerant. If it is hot and the tube coming out of the expansion valve/orifice is cold, this is the way it is supposed to be. If the tube on the outlet of the evaporator is not cold, then you are low on refrigerant or the expansion valve/orifice may be bad.
