2008 Monaco Camelot, electric water bay heater quit. Found the in-line snap disc switch visible from open bay door, mounted about 8 inches up and I had to look from a low position or use a mirror to spot it. Medium phillips head screwdriver removed the two screws. Wires pull off from the blades of switch. System Heat switched on, Jumped wires and heater worked, thus snap switch defective.
As for replacement part, on at 45 degrees and below
and cuts off at 60 degres and above
