Trane ECGAH 250 SENSOR
Hi
We have a customer with the above chiller showing a sensor fault
A sensor 3 1/0
We have tried swapping the sensors around but the fault remains the same, ( There are 3 sensors)
Resistances between the sensors are similar , Trane want £80 each for the sensors, so we want to be sure to get it right first time
Anyone know an alternative sensor or has any experience on this fault
Thanks

Re: Trane ECGAH 250 SENSOR
Thanks for that I am even more puzzled !
think i need to go back to site and do a few tests as that doc seems to refer to a pressure sensor,
From the schematic info on the unit I presumed the fault was one of the thermistors but maybe its a pressure transducer issue

Doc.
it's saying either could be present check which, and use parameter limits specified to decide which is the issue?
It is telling you where to look now instead of 3 options as before.
