I was just wondering if anybody has had problems with the J/C P-266 fan speed controls. I have a customer that has six new Koolant Koolers chillers with P-266 controls on the remote condensers. They are only around two years old and two of the P-266's have been replaced. I found another one today that isn't working. The fan runs at full voltage & speed with a call for cooling. They don't seem very reliable for the cost.
