Earlier, I was at the local aircon parts supply here in the province and they confirmed that the mechanical thermostat has a different calibration from the electronics thermostat which confirmed my theory earlier. In this regard, I have no choice but to look for a supplier for the thermosensor.
So let me get this straight... The OEM sensor is the Zexel part no. you mentioned in the beginning of the thread. Then it became defective, so a mechanical thermostat was used in its place. That’s when your issue started happening (compressor turns off prematurely). Did I get the sequence right so far?

If yes, here are my questions:

1. What were the problems or symptoms you encountered that prompted you to determine that the OEM sensor (Zexel) was the culprit?
2. Did the issue with the compressor prematurely shutting down happened immediately after installing the replacement mechanical thermostat, or did it only started happening after a while (days, weeks, months, etc.)?
