Short Cycling from High Pressure Protection Activation
Likely causes
High pressure rise from condenser fan failure
Check: Verify condenser fan is running
What to do: Verify condenser fan is running → Clean condenser → Check high-side gauge reading → Refer to 'High Pressure Switch Keeps Tripping' diagnostic tree
Poor heat rejection from condenser fouling
Check: Clean condenser
What to do: Clean condenser → Check high-side gauge reading → Refer to 'High Pressure Switch Keeps Tripping' diagnostic tree
Refrigerant overcharge or non-condensable gas
Check: Check high-side gauge reading
What to do: Check high-side gauge reading → Refer to 'High Pressure Switch Keeps Tripping' diagnostic tree
Field tip
High-pressure switch is repeatedly tripping. Refer to 'High Pressure Switch Keeps Tripping' to resolve the root cause.
