What causes excessive section pressure in a Carrier 38QH30-H?
Excessive section pressure in your Carrier Air Conditioner can be caused by a reversing valve that is stuck or has an internal leak, in which case it should be replaced. Another cause could be an internal pressure relief valve that is open; check for the source and eliminate it. Overcharging the refrigerant can also lead to this issue; purge any excess refrigerant.
What causes low head pressure in a Carrier 38QH30-H?
Low head pressure in your Carrier Air Conditioner can be due to a low refrigerant charge. In this case, check for leaks, repair them, and recharge the system.
