When a refrigeration system producing low to normal refrigeration operates continuously without stopping and has high suction pressure and high head pressure , the probable cause is 1. an inefficient compressor 2. a low side restriction 3. noncondensables trapped in the condenser 4. an undercharge of refrigerant
