can i do anything to diagnose duo-therm dometic penguin?

it runs but it isn't cooling the air. i think the thermostat let it shut off as i pushed it toward 80 deg. it's in an '05 22 ft trail lite. a few pics follow. any tips, ideas, insights are much...

thx, ron, i will keep that in mind as i progress...

what seems to be called a 'freeze control sesor' dropped down and i do not know if i just caused it or if it happened in past.



it appears to need to be clipped to something related to the coils directly above it (loosely gleaned from some discussion group), so i put it on a copper coil loop ----(right, wrong?)

the 3 amp fuse from hre looked OK
