So recently when I left for work the furnace was working. When I returned home it was not working one bit. No furnace, no blower, no action of any kind.
Things checked:
Replaced thermostat.
Quadruple checked all the power.
removed furnace filter (was pretty dirty).
Control board was producing no error codes so I replaced it.
Furnace still does nothing.
Checked blower fan, spins freely.
Bought an electrial checker widget, and there appears to be power flowing into the control board, into the blower power line and out into the transformer. There is no power flowing out of the transformer. I could not find any other power flow.
From this information might anyone have an idea what to investigate next? Bad transformer? Does the transformer output power that is not checkable by the electrical sensor widget?
