Possible Causes

Safety first: Do not attempt to connect gauges or add refrigerant unless licensed.

Step 1 – Airflow check: Ensure filters are clean and coils are not iced, as poor airflow can mimic low charge symptoms.
Step 2 – Visual leak check: Look for oil residue on service valves, braze joints, and coils.
Step 3 – Reset: Power cycle the system and monitor operation. If P1 returns, shut the system off.
Step 4 – Technician required: A licensed technician must locate and repair leaks, evacuate, and recharge the system to Keeprite specifications.
