My baseboard heater is not heating up properly. I took a meter and tested the line and the load side in the heater and in the thermostat. I only have power in the line side (120 volts) but when I tested the load side no power in the baseboard or in the wall coming into the thermostat. Is this normal. Do I have a problem with my electric wiring?

I will assume the thermostat is built into the heater, and this is where you can measure 240 volts on the line side of the stat, and zero volts on the load side.

If this is correct, the stat is defective.

Thank You for your response. I have one of the old dial double pole switch thermosta tin my wall, forgive me if I failed to explain everything right. The baseboard heater is new. I replaced an old one because it was barely heating up now this one is barely heating up. I don't have a thorough understanding of 240 volts, but do understand some. When I took the dial/switch thermostat to test I have two romex wires coming in to the switch box. Each black has 120 volts on it. The wiring diagram on the switch cover states line side on the left, load side on the right. The white wire inside the romex are connected to red extension wires with wire nuts and are both in the top two slots in the double pole switch. The black are in the bottom two. The wire diagram on the switch read both red line on the right and both black on the right load side, Is the switch wired wrong because both black wires are on the bottom, One on the line and the load side. I know it is probably hard to picture with all this mumbo jumbo, but thanks for the help.

So you don't have 240 volts feeding the stat?
