Fan speed read out not working, drum speed and forward speed working ok so any ideas where to check first?
Where is the sensor for the fan speed?- I dont see it on the end of the fan shaft??

Cab steps side of fan shaft. I’ve got the same symptoms and I am going to change the sensor to begin with.

These are simple reed switches operated by a magnet on the shaft, check connections all the way back to main box use cleaning spray as the slightest bit of corrosion will cause problems.

Had a look and cleaned the connection but still no luck.
If I can pick a sensor up I will try that next.

Did you get sorted?, where did you get the sensor, was it just off your main dealer?.
I cant get mine working so going to have to try a sensor.

I'll give that a try in the morning.

Just looking to change it now. I got the part off eBay but would use APH otherwise.

Its the sensor on mine- I swapped it with the returns sensor and the fan speed works again.
I took the sensor apart and it was full of dirt/dust which corroded part of the inside.

Just rang my mate for he is into this kind of electronics and he came round.
He passed a magnet over the switch and said you can hear it clicking if it is working.
He took it away to replace the reed switch inside which he says costs pence
CNH wanted £90.

 

[Will Blackburn]

£50 on eBay, that’s more than enough.

Ours has done the same as this except with the forward speed, just get a full stop on the display. Is it likely to be a reed switch and if so where is it located?

 

[Alwaysinit]

Ive no idea about the forward speed, but im curious now you have mentioned it.

 

[Will Blackburn]

There’s a sender in the top of the transmission?
