Thermo/switching valve

I am trying the determine whether the thermo or the switching valve is bad on a Detroit series 60. Fan is running hot so I disconnected the 2 lines from the thermo valve & connected them together with no change in the fan speed. I did not block both lines because the fan speed did not change. I am assuming that the only other thing could be the switching valve. Therefore I am wondering if there is a way to test if the switching valve is operating properly. Any advice as to how to determine what is causing the problem would be appreciated.
I have a 2005 Monaco Signature Conquest 44'

Thank you.
Tony

If its a variable speed fan, the default is usually full speed. That's so that a control failure still provides adequate cooling for any situation.

I suspected a problem with my thermovalve and contacted Monaco Tech support and they told me to do 2 things.

plugged both lines and the fan ran wide open.

put a union in between both hoses and the fan ran at an idle

These 2 tests show that the switch control is good and that the thermo valve is bad.

I bought a thermo valve from White House Products in UK, cost ~$265 including shipping and Exchange rate.

My part # is 553/1/09857/210 THERMO VALVE took about a week to get after placing order.
