Short Cycling from Low Pressure Protection Activation
Likely causes
Refrigerant leak or insufficient charge
Check: Check low-side gauge reading
What to do: Check low-side gauge reading → Inspect for refrigerant leaks → Check evaporator frost condition → Refer to 'Low Pressure Switch Keeps Tripping' diagnostic tree
Low pressure drop from excessive evaporator frost
Check: Inspect for refrigerant leaks
What to do: Inspect for refrigerant leaks → Check evaporator frost condition → Refer to 'Low Pressure Switch Keeps Tripping' diagnostic tree
Expansion valve blockage
Check: Check evaporator frost condition
What to do: Check evaporator frost condition → Refer to 'Low Pressure Switch Keeps Tripping' diagnostic tree
Low-pressure switch is repeatedly tripping. Refer to 'Low Pressure Switch Keeps Tripping'.
