Re: Why is my electric baseboard not heating up?
I kinda agree with bsum1 in that the thermostat could be faulty.
However, since the thermostat is powered up would indicate voltage is fine from the breaker to the thermostat.
It's possible the wire connections from the thermostat to the baseboard heater may have an open condition.
It may very well be in the box the thermostat is mounted. Likely there are wire nut connections --- check those to make sure they are tight and proper.
Also confirm the connections at the heater.

You could also disconnect the wires from the back of the thermostat and connect the Line ( from the breaker ) to Load ( to the baseboard heater ) matching color for color.
Turn the breaker on and the heater should start to warm up.
If this is the case then it's the thermostat.
If it doesn't then there is an open condition between the wall box and the baseboard heater.
Usually the cables don't fail unless they have been cut ---- more often it's at a junction ---- wire nut or screw terminal. There are occasions when the copper breaks off under the wire nut or screw connectors.
