There is also a heat element.. To test.
Locate the heater.. find the wires to it and parallel an indicator (small light bulb or AC volt meter) I won't go into how to do that.
Fire the sucker up
Light come on meter show 120 Odds are the element is toast Resistance measurement of the element is diagnostic.
NO light/voltage. Control board or bad connection or blown fuse or bad cord/socket (plug in a lamp or drop light to test) or .. Well long list.
Oh if the eyebrow (The lights inside above the thing) do not come on ...
Pull eyebrow out and find the big multi-pin connector. Unplug and replug several times.
Then go outside find the control board (mine was on the left) and do the same thing several times.. Try again.
Finally.. ON MY Dometic there was a terminal board (no electronics just a fuse or two and wires) dead center bottom outside RIGHT UNDER THE BLASTED DRIP TUBE.
This tube is supposed to go out a vent hole so it drip, drip, drips on the ground. NOT left inside to drip,drip,drip on that board but .. well.. (I fixed it twice)
