Mainepilot Posted July 23, 2016 Report Share Posted July 23, 2016 Inconsistent cooling. . . STATS: Low pressure is 36PSI At times Compressor runs 5 seconds on / off for 15 seconds, & repeats for around 90 -120 seconds. May run perfectly for another 20 minutes, then repeats the same problem. I'm extremely good at mechanical, and somewhat good at electrical. My intuition tells me a sensor is faulty? Any input would be helpful Quote Link to comment Share on other sites More sharing options...

Mainepilot Posted September 7, 2016 Author Report Share Posted September 7, 2016 SOLVED - Too much refrigerant in the system. Although well in the green arc on the gauge,& on the high side of center, I would recommend slightly lower than center green. For some reason, Ford Edge requires a very narrow range for refeigerant quantity. The high pressure "shut down" kicks in, until pressure drops, and this cycle repeats. 3 Quote Link to comment Share on other sites More sharing options...
