We've got an electric baseboard heater that doesn't work. It's got a
unit mounted thermostat, which seems to work, as the resistance goes
from infinite to zero at some point as you turn the knob. It's then
got a thermal overload protector thingee, which has a resistance of
120 Ohms, which seems way high. Then there's the heating element
itself, which has a resistance of less than one Ohm, which seems
awfully low. (I'd expect it to be about 120ish Ohms, given the 1000
watt rating and 240 wall current. ) I'd expect the thermal cutout to
be very low resistance, unless it's tripped, in which case I'd think
it would be open. And I don't see how a heating element can have
almost no resistance.
What's going on?
