Help protect your A/C compressor from unsafe refrigerant pressure with the Four Seasons HVAC Binary Pressure Switch, part number 20947, a system-mounted switch that monitors pressure in the air conditioning system. It fits many Honda vehicles, among them the 2008-2009 Honda Accord, 2002-2006 Honda CR-V and 1995-1998 Honda Odyssey. It is a direct-fit replacement for the listed applications, and the Buyer's Guide tab shows the full list.
A binary pressure switch has two states. It is designed to interrupt compressor operation when refrigerant pressure falls too low or climbs too high, which helps keep the compressor from running outside safe limits. Four Seasons engineers and tests its products and brings more than 50 years of mobile A/C experience to this switch.
- Corrosion protection: Zinc coated to resist corrosion.
- Vehicle-specific: Built for the listed vehicle applications.
- Sealing components: Comes with the gaskets, O-rings or seals needed for a proper replacement.
- Easy identification: Color coded so the switch is easy to identify.
Signs the switch may need replacing include a compressor that won't engage, a compressor that cycles erratically, and warm air from the vents. Low refrigerant and other faults can cause the same symptoms, so diagnose the system before replacing parts. If a failed binary switch is the cause, this unit replaces it.
