While working on the thermostat I accidentally touched some wires and there was a spark.
The fuses on the box for the thermostat and furnace are fine.
The thermostat does displays all functions, however, it will not turn on any of them.
Using a needle type tester there appears to be electricity flowing through the slots except the one labeled white.
Is there another fuse somewhere?
Our thermostat is a Airxell 9430.
Our unit is the Jayco Seismic 4212 toy hauler.
WHITE should be the 12 volt pos feed TO the furnace to activate it. When in furnace mode. Doug
