Dometic reefer check light

There are basically two things that set off the CHECK light or fault light.
One: failure of the flame sensor to sense flame after a set number of tries to ignite the burner..
Two: A manual reset thermal beaker or a blown thermal fuse (I do not recall if there is a thermal fuse).

Since this is the easiest I'll describe the breaker.. Go out and remove the access panel.. On the right side is a round "Tube" (chimmny/flu whatever you want to call it) the burner is at the bottom...
Part way up. is a small round thing with two wires.. There is a button in the center. PRESS HARD and see if that fixes it.

As for failure to sense flame.. That's a more complex procedure but you can LOOK have yoru partner activate the thin (While it's warm inside the cabinet) while you watch the burner.... If it's flame on you will see it.
Common issues are poor flame (Caused by lack of maintenance or a spider)
and sensor chip (This is on the control board) failure.. also bad electrical connetions.

NOTE: There are two flame detector/ignigition systems Single wire and Multi wire. IN single wire the same wire that carries roughly one THOUSAND volts to make sparks... also carries about half a volt to say "I'm hot, Flame ON" if you can see a possible issue here.. Well I agree.
