High Pressure Switch

A high pressure condition can result from insufficient air flow across the condenser. When this happens, switch (A) shuts off the compressor and light (B) indicates that the high pressure switch (A) has stopped the air conditioning system.

Stop harvester and clean condenser:

  • Shut off engine, remove key and set parking brake.
  • Clean condenser and filters (see also "Service - Engine" Section).
  • Check for a broken fan belt.

If indicator light remains on after cleaning condenser, see your John Deere dealer.
