IMPORTANT: Electrical items are covered by a 30 day EXCHANGE ONLY WARRANTY. There are no returns or refunds on such items.This switch turns the radiator cooling fan on when the a/c system high side pressure reaches approximately 238 PSI. Air flow across the a/c condenser is imperative to prevent high side a/c pressures from causing system damage (blown hoses typically).When the a/c pressures go above 350 PSI so does the temperature of the refrigerant on the high side. The resulting temperatures can also damage compressor seals.
