Turn Power On and Test the Baseboard Heater Thermostat
Now that the connections are made to the baseboard heater thermostat, heater, and breaker, turn the circuit on and test out the thermostat. Turn the thermostat clockwise to trigger the thermostat switch. You’ll hear it click when the contacts pull in and there should then be electricity flowing through it. In a few minutes, you should feel heat coming form the baseboard heater and your project should be complete.
