We have a bedroom in attic that we seldom use. But with holiday houseguests
it is getting use. But, the electric baseboard heater is not working.
We have fuse panels. This particular room's heating is not identified, but
perhaps it shares a circuit with another heater? Anyway, I removed all fuses
and checked each one. No bad fuses.
The heater is controlled by a wall thermostat - It has white and black wires
coming to it - The thermostat breaks the white wire only, the black wire
really just passes through. I checked voltages - nothing across the white &
black on either side of the thermostat. But from either black or white to
ground (the box), I get 110v. Just is case, I changed out the thermostat for
a spare, but no change.
At heater, it is the same - no voltage between the incoming wires, but 110v
to ground from either side.
Questions:
- If I see 110v to ground from black & white, why don't I see 220V across
these conductors?
- If I see the 110v to ground, does that mean that I do have power to the
heater?
Any suggestions as to how to further troubleshoot this problem?

Each wire should be 110 to ground, 220 if you contact both of them. The
thermostat is breaking just one wire. If it is the stat, you can get heat
by twisting the two wires together.

This is what I would have thought, but the puzzle is that I get the 110v to
ground, but not 220v across the hot conductors. Changing thermostats made no
difference, so unlikely a thermostat problem.

That indicates both "hot" wires are connected to the same phase
somewhere -- either at the fuse box or at some other junction box,
somebody made a wiring mistake and got both of them on the same side.

It indicates one leg is open. The 120 is passing thru the element.
