You can check the heating element by checking continuity thru the unit. You
have to remove all the power (12v AND 120V) from the trailer, remove the
cover on the lower left side (looking from the back). Follow the wires
coming from the vertical tube at the right side of the fridge (as viewed
from the back (about 6" above gas burner) over to the circuit board behind
the cover that you removed. Unplug the connector from the circuit board
whose wires go over to the vertical tube on the right side. With an ohm
meter, see of there is continuity between the two pins in the removed
connector. If there is continuity, then the heater tube is okay, if there
is no continuity, then the heater is shot.
