Cooling fan staying on high speed

2015 Newmar London Aire, ISX 600hp. Engine temp isn't high. Dash display says "air cond" which means hi speed. It's always gone on and off in the past. Turning off dash air has no effect. It stays on high speed.
Anyone run in to this situation?

There are going to be a ton of differences between my vintage chassis and yours ; but my 99 has a rad fan control module ; and I've had two failures of the module.
I'd say a call to Freightliner's free help line is in order ; with your serial number .
1-800-385-4357

Note: In the event of issues with the control the rad fan default is supposed to be high speed ; in both my control failures the fan, ran on low, and I overheated.
I now know where to disconnect to force the fan to run on high. Not great for fuel mileage , but gets me off the side of the road in a hurry.

Thanks Chip,
Talked to Freightliner and the rep was no help. Called Freightliner dealer 30 miles from here who I've dealt with before(good service location) and he indicated that they've had instances of fans stuck on high, stuck on low, etc and felt sure they can fix it. We plan to go there next week.

My cooling fan speed has two speeds, off and 100% on. It comes on every time the dash air is on and if the eng temp gets over about 223 it will cycle on/off.

Good luck.
Iíve had more problems with the Sauer-Danfoss fan control circuitry in our side radiator Freightliner coach than everything else combined.
It is now at Cummins in Mishawaka, IN having the Source Engineering Thermal Valve (the wax valve) conversion installed. I have had it up to my eyeballs with that damned Danfoss controller. No more.

Thanks A Traveler,
I'm headed to Nappanee in a couple of weeks and may very well end up at Cummins too. I don't plan to run dash air on the trip and see what happens with fan speed.

John,what chassis is your LondonAire coach built on?

I ask because if it is a Freightliner chassis, there is a little extra work required to install the Source Engineering Thermal Valve kit.

PM me for details.
