Tried to use our Pentair heat pump for the first time this year and it's throwing a "Low Refrig" error shortly after starting up. Had a Pentair technician out today who tested everything and the only sign of dysfunction that he noticed was the main capacitor was testing out of spec, although the unit successfully heated and cooled the entire time he was here (of course!). The quoted price for the capacitor was $400+ plus labor so I told him that I'd see about locating the capacitor online and installing myself (hopefully it's easy enough).
Does anybody have experience with this "Low Refrig" alert? Refrigerant pressures tested fine, no leaks, low pressure switch was good, fan runs at expected speed. Is it possible that a failing capacitor would cause a "Low Refrig" alert?
