Hi all. Have a suction line temp sensor reading -47 degrees, which is what it will read
for an open circuit. So I changed the sensor and still had -47. I then disconnected both the return air and suction line temp sensors and they were both getting 2.6VDC.
I then cut the wiring at the microprocessor and connected the suction line sensor directly
to wires 1MP19 & 1MP32. It is still coming up with -47 degrees lol.
I'm assuming its a micro, but just finding it hard to believe when there is an identical
voltage to that of the return air sensor which is reading fine.
Im not overlooking anything like a configuration error?
Any help appreciated
