PT-42 Front Heaters

[mbrund]

I believe the one you are talking about at mid-ship, which would be
at floor level below the draws is the electric heater. This is
controlled by the thermostat that is mounted near the kitchen on
most coaches. This is a standard analog type thermostat, on my 92
it is mount right at the edge of the kitchen counter above the
couch. If you place the left most switch on heat, and set the temp
with the upper dial it should turn on this heater. The catch is
that the front AC switch on the dash to the left of the steering
wheel that conrols all the coach AC's (there are total of three
switches front, mid, rear) the front AC must be in the on position
as it controls the electric relay to that heater.

Which temp controls in the dash are you talking about, the overhead
dash (Chassis AC), or the lower left dash where the chassis heat is
located?
