7120 fan speed switch replacement???

Recommended Posts

I need to replace the fan speed switch in my 7120........can it be accessed from inside the cab (I hope) by removing the switch bezel or do I need to lift the cab roof?

Thanks!

Switch panel only...just be careful how far you pull it out as capillary tube on thermostatic switch will come out with panel or maybe take nut off it an allow it to stay back while you pull panel out.

Might want to check the fan motor resistor to be sure that is not the problem before replacing the switch . I have replaced far more resistors than switches .

I am pretty sure it is the switch as sometimes you have to turn it a little "off' of the actual position of where it should be to get the fan to run. When you play with it a little you can get it to run on all of the speeds.
