if thats where you run it at 40 i suspect it's overheating and shut off possibly broken now , one should never set a humidistat less than say 66%rh as a normal house is 70%rh and asking anything more of a home unit is just not possible if moisture is that much a problem try running two units about twenty feet apart , they will cycle more to cool down and will run longer , might even be more efficient than running one harder

You can't, it uses freon.

totally dead, check fuses. could be stiffened up over the time and took fuse out on first switch on

Look in the owners manual for codes

Sounds like a refrigeration problem, I am assuming the fan operates. Unplug it and let it set for about an hour. Plug it in and see if the compressor starts. If it does and you do not get water It is either low on gas or the compressor has failed. If the compressor does not start but hums it would need a new capacitor. If nothing the thermal overload has probably failed. This should get you started. Good Luck. If it is to involved they are not that expensive to replace.
