    19xr thrust sensor

    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.

    You might want to apply for pro membership and take this into the pro forum.

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    In order to change the sensor you will neet to remove the transmission section to get access to the sensor.This would be pretty much a complete teardown.Not something you would do just to change a sensor that is still working. If the oil analysis comes back bad , then would be the time to take the whole machine down and replace the sensor.

    thanks for the help everyone if it needs a teardown/overhaul/rebuild sounds like a job for carrier. Boss wont send me to teardown class or invest in the equipment/tools. I quess we are going to do waterside repairs and leak repairs that dont involve inside the compressor. Going to go to the maintenace class. Any tips on changing driers, oil, etc.

    If you have never done this maintenance before, you may be in over your head. You should seek the help of a qualified tech in your area and ask for assistance for the first time.

    spinning wheel speaks the truth. Even something as simple as changing the oil and filters can bring disaster if you dont know what you are doing. You might want to at least sit down and read the SOM manual on routine maintenance first.

    Just because the chiller tripped on High Thrust Bearing temp doesn't necessarily mean the sensor is bad.
