So if the OD was much above 85F the head pressure was on the low side001_unsure. 8For any refrigeration cycleAC unit there are two operating pressures. But the low air problem would result in high head pressure in the heat cycle. Check also: pressure and hvac high head pressure low suction Check to see if the unit has an expansion valve on the evaporator inlet.
The resulting symptom will be a lower head pressure with a higher suction pressure. The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to.

Low suction pressure is usually do to insufficient.

Apart from refrigerant leaks causing loss of critical charge the most common problem associated with low suction pressure is. Bad or leaky compressor valves. Turn off the condenser fan unit and see if the pressure does not fall. If it does not then the problem is likely condenser valves. These factors will put a very light load on the compressor and cause the amp draw to be low. 7Poor insulation doors left open or defrost heaters running continuously.
