A/C System Was Left Open To The Environment For An Extended Time
Ambient moisture entering the air conditioning system has depleted the receiver/drier desiccant. Debris might have entered the end connections of the open components. Perform the following:
- Replace the components that have end connections that were left open.
- Vacuum A/C system to remove any moisture potentially trapped.
- Replace the receiver/drier desiccant bag if any of the following conditions occur:
- Refrigerant circuit is open for >20 minutes.
- Amount of refrigerant extracted is < 30% of the required quantity.
- Refrigerant circuit has been open for an indefinite period of time (gradual leak, exterior damage to condenser).
- Recharge the refrigerant.
