LOW-PRESSURE SWITCH — PROTECTS YOUR A/C SYSTEM
LOW-PRESSURE SWITCH — PROTECTS YOUR A/C SYSTEM
Your A/C low-pressure switch is a safety device that monitors refrigerant pressure and helps protect the compressor when pressure drops too low.
✔ Protects compressor from damage
✔ Helps detect low refrigerant conditions
✔ Shuts system off when pressure is unsafe
✔ Supports efficient cooling operation
✔ Important for system reliability
⚠️ If this switch trips often or fails, your A/C may stop cooling, short cycle, or run improperly.
Common signs:
• Outdoor unit not running
• Warm air from vents
• System turns on and off often
• Frozen evaporator coil
• Low refrigerant issues
• Intermittent cooling
Low pressure problems can be caused by refrigerant leaks, airflow restrictions, dirty coils, clogged filters, or metering device issues.
Regular maintenance helps keep pressures balanced and safety controls working properly.
Small switch, major protection — don’t ignore low-pressure issues.
