AC condenser fan not getting power

I have a Damon 01 pusher and I had to replace the AC condenser and fan on the unit in the rear next to the engine. The condenser fan does not run. I checked the voltage and there isnít any power coming to the fan at the disconnect between the fan and the power source. Iíve read a couple old threads concerning the fan pressure switch which is said controls the fan operation. My question is where might the pressure switch be located and also would there be an inline fuse involved or perhaps a fuse up front involved as well? How might I ID the switch as I look for it. My chassis is a freightliner if that helps. Any suggestions

I am sorry I can't speak to your specific motorhome but the pressure switch is usually located on the dryer for convenience sake(theirs, not yours). It is usually a 3 function switch: low pressure protection, high pressure protection and a pressure override for electric fans or fan clutches. That means that there may be nothing wrong with yours since you should not have current when the system isn't in a high head pressure situation.
In addition to the fuse, you probably have a relay. I would think they would be located wherever Freightliner mounted their fuse panel. The fuse and relay location is dependant on who did the install. Condensers now routinely come from the chassis supplier. That was not always the case.

My first question would be IF the AC compressor clutch is engaging or not when you turn the AC on?
