For a high-pressure suction to occur you could have an insufficient compressor. Meaning your refrigeration has a leaking discharge valve. This indicates that your compressor cannot provide the needed refrigerant to the evaporator to handle the cooling load.

What is the most common cause of high head pressure?
Bad Fan Motor This is actually the most common issue that causes high head pressure. You can have a bad fan motor due to a few different reasons. Your fan blades naturally wear down over time. The process of them wearing down can be expedited by debris finding its way into your air conditioner's outside unit.
What are two things that can cause high discharge pressure?
The main reason of high discharge pressure is high condensing pressure. Insufficient heat dissipation of condenser, fouling, insufficient cooling air or water volume, high cooling water or air temperature can lead to high condensing pressure.
What effect does too much refrigerant in a system have?
Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.
What Causes A High Suction Pressure And A Normal Head Presssure
What can cause a high discharge pressure in a refrigeration system quizlet?
What can cause a high discharge pressure in a refrigeration system? Low evaporator level.
What causes increased suction pressure?
Overcharging leads to overfeeding the evaporator with refrigerant, which leads to higher suction pressure. Another possibility is having oversized EXV causes an overfeed to the evaporate, which increases your suction pressure.
What causes a high discharge pressure?
One common cause of high discharge pressure is the cooling medium (air or water) flowing across the condenser: either there is not enough or the temperature of the cooling medium is too high. This is normally easy to identify with a simple visual inspection of the condenser.
Do Line Restrictions Cause High Head?
Which of the conditions listed may be an indication of an excessive amount of refrigerant circulating through the system?
Which of the conditions listed may be an indication of an excessive amount of refrigerant circulating through the system? Sweating of the compressor crankcase. An evaporator coil of a single evaporator, air-cooled refrigerator is accumulating excessive frost due to a failure of the defrost mechanism.
What causes high head pressure and low suction pressure?
Excessive refrigerant, higher outdoor temperature, improper cleaning of coils are the main reason for both pressures. Suppose the evaporator is not getting sufficient refrigerant from the compressor. It will not be able to provide proper cooling in the system. This problem can cause low suction pressure in the system.
Liquid Line Vs. Discharge Line
What causes high head pressure and high suction pressure?
Overcharging of refrigerant, liquid slugging of the compressor, oil contamination and other sources can damage compressor valves. Refrigerant overcharging will show up as high head pressure, normal suction line pressure, normal superheat, high sub-cooling.
What causes high suction pressure and high head pressure?
The main reason behind the high suction pressure is excess amount of temperature and pressure is present in the system which is flowing from the compressor of the air conditioning system.
