Hi Forum,
I have a John Deere climatic controller with 3 potentiometer with defect resistor values snd wrong behaviour.
Does any body known the manufacturer of this devices?

Thanks a lot

Something like this?

https://www.bourns.com/pdfs/3382.pdf (datasheet)

It looks like Murata makes them also:

I believe it is the Panasonic EVQVVD00203B.
There is also a resistive rotary position sensor with a similar shape, made by ALPS or Bourns, I believe.
I would have to see the circuit to be sure, but I think it is an encoder.

We also found a resistive rotation sensor with the same shape.
Please check the circuit.

Thank you both so much!
 
The Panasonic type fits perfectly, now I need to check where to order in Europe.

Psi:
The PCB has a hidden internal battery and the MCU has already detected tampering and entered a fault state, so it will require dealer codes to unlock it.

Ok, I'm mostly joking, but you never know with John Deere.
