Too high of a superheat can cause the heat of compression to increase, causing the temperature at the discharge valves to increase. If the temperature increases beyond its safe operating temperature, it will cause damage to the compressor.Click to see full answer. Similarly, it is asked, what is the problem when the superheat reading is too high?Possible causes include a metering device that is underfeeding, improperly adjusted, or simply broken. Additional problems with high superheat could indicate a system undercharge, refrigerant restriction, moisture in the system, blocked filter-drier, or excessive evaporator heat loads.Furthermore, what are the symptoms of an overcharged AC system? In summary, there are seven symptoms or telltale signs of a system that has too much refrigerant. High discharge temp. High subcooling in the condenser. High pressures in the condenser. Higher condenser splits. Normal-to-high evaporator pressures. Normal superheats. High compression ratio. Also, what would be the symptoms of too much superheat? Symptoms of this overcharged system include: High discharge temperature. High condenser subcooling. High condensing pressures.What happens if you overcharged refrigerant?The main danger with too much refrigerant inside an air conditioner is that it can damage to the compressor. The excess refrigerant will collect inside the compressor and lead to subcooling, temperatures below normal. An overcharged air conditioner will also create higher pressure inside the system.
