How can I check if power is getting to my thermostat?

You can also conduct this test with the red power wire and the (usually white) wire connected to the W terminal. It controls the heat and will also make the blower come on if the thermostat has power. If you happen to have a multimeter, you can test the thermostat without turning off the power or disconnecting any wires.
