How do I Install an Air Conditioner Liquid Line Dryer?
Moisture and contaminants wreak havoc on any type of air conditioning or refrigeration system. They are usually introduced to the system through improper servicing of the unit. The liquid line dryer is located between the condenser and the expansion device. The purpose of the dryer is to trap particles and moisture. If any particles or moisture reach the expansion device, they will accumulate and restrict the refrigerant flow. Another problem is that when they mix with the oil an acid is formed which eats away the compressor windings as well as other parts of the unit. The dryer might be a flared or a sweat (soldered) connection.
