A/C PRESSURE SWITCHES — IMPORTANT PROTECTION FOR YOUR COOLING SYSTEM
A/C PRESSURE SWITCHES — IMPORTANT PROTECTION FOR YOUR COOLING SYSTEM
Your A/C pressure switches monitor refrigerant pressure and help shut the system down when the pressure becomes too high or too low. This protection helps prevent the system from operating under unsafe conditions.
✔ Monitors refrigerant pressure
✔ Helps protect the compressor
✔ Prevents operation under unsafe conditions
✔ Helps identify possible system problems
✔ Reduces stress on major components
✔ Supports safe and reliable cooling
⚠️ Abnormal refrigerant pressure may be caused by a refrigerant leak, dirty condenser coil, restricted airflow, failing condenser fan motor, incorrect refrigerant charge, or refrigerant restriction.
Common warning signs include:
• A/C repeatedly shutting off
• System short-cycling
• Warm or inconsistent airflow
• Ice on the refrigerant line or evaporator coil
• Outdoor unit overheating
• Compressor failing to start
Never bypass a pressure switch. If it shuts your A/C down, a professional technician should inspect the system and correct the underlying problem.
Protect your compressor and cooling system with properly functioning pressure switches.
