Using feedback from valued customers and routine analysis of available warranty claim data, Enertech Global has identified a negative trend in the quantity of low pressure switch failures. When these pressure switches fail, the metal housing tends to crack, disintegrate or disengage from the actual plastic switch. The defective switches have been traced back to a single supplier that was used in all units manufactured between April of 2014 and mid-January 2016.
