Just got a account with 4 carrier 19xrs, one of them has had a high thrust bearing temp 4 times since 2009. Was told the sensor wire was changed to the spare. Should it be torn down for inspection and should the sensor be changed with the bearing. I am thinking it is a project to change just the sensor.Today it was running the same as the others stayed the thrust bearing temp stayed in the 130s. The load has been greatly reduced in this building.
low load conditions.
