Low Pressure Switch

This switch (A) (located under passenger seat) protects the compressor if refrigerant is lost. The switch can also activate if there is insufficient air flow across the evaporator. It can also cause the compressor to cycle on cool days or if there is a slow leak in the system.

Clean condenser and filters.

Check recirculating blower.

Check for a worn or broken serpentine engine belt.

If the compressor cycles excessively, or if there is no cooling, see your John Deere dealer.
