What should the low side refrigerator pressure be on a refrigerator while it is running?

My high and low pressure r134 readings are 90-95 each.what should the refrigerant r134a high and low pressure readings be?
If the pressures are always equal running, the compressor is bad and would need replaced
What should the high and low pressures be for 404A refrigerant on a refrigerator?
18-20psig suction 250-270 psig discharge In freezers pressures are ok .I got it ,but the mention pressure of suction 18-20 discharge 250-270 at what temprature in centegrade it should be.
How much should be Condenser pressure in an ac with r-22 refrigerant?
300psi
What safety precaution should be adhered to for low pressure system?
do not siphon refrigerant by mouth
What should the low pressure be on a hvac system?
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
What does on refrigerator High side 240 Low Side 110 mean?
A refrigerator is basically an air conditioning system. There is a high (discharge) and a low (vacuum) side to such systems. As it goes through the system, the refrigerant will change state (e.g., high pressure vapor to high pressure liquid, high pressure liquid to low pressure liquid, low pressure liquid to low pressure vapor, low pressure vapor back to high pressure vapor). This facilitates the absorption of heat from the refrigerator compartment and the exchange of that heat to the ambient air. What you're seeing there are the pressure readings (in psig) of the high pressure and low pressure sides of that system. Your refrigerator and an automotive AC system use different refrigerants, and thus have different system operating temperatures. While those numbers would be excessively high on an automotive system, I don't know if that's the case with a refrigerator. You'd need to inquire with a qualified service professional on the matter of what your refrigerator's operating pressures should be.
What is the refrigerant pressure on the low side for the ac?
R134a refrigerant pressure should be around 28-32 psig with good airflow across condenser(radiator)coil and engine rpm at or around 1500
Food should be defrosted in the microwave under cold running water or?
in the refrigerator
Why a refrigerator should not be switched on immediately after being switched off?
When turned off it is possible for gas bubbles of the refrigerant to mix with the liquid refrigerant in the pump. If the refrigerator is immediately turned back on the pump will turn this mixture to a froth that it is unable to pump and the refrigerator will not function. The pump motor can overheat and in some cases burnout or even catch fire. Waiting a few minutes before turning back on will allow the refrigerant bubbles to separate from the refrigerant liquid, preventing the pump from making a froth and allowing normal operation.
You have a subaru legacy 1991 the ac stopped working the compressor is engaging on and of constantly did put cooling in it but still dus not work Have anybody any idea where to look for the problem?
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.
Why won't the AC fan turn on your 1996 Dodge Grand Caravan No leaks no cold air comes out and will not take R-134 with self filling hose?
AC compressors need to be running before the system will pull in refrigerant. Find the pressure switch and jumper the wires with the engine running and the AC turned on, that should engage the AC clutch, pulling in the refrigerant. Keep an eye on the pressure gauge though. Don't overfill or you can destroy the compressor seals.
