+1 The collection of condensate lines usually go to a box, which might have a mess of crud clogging it.

My understanding of roll out switch is over heating by some cause.
The switch usually has a tiny button(usually red in color) which will
pop when triggered. First thing to try is try again after resetting the

power off, wait a few seconds and turn back on.
