      First, ensure that the power is on at the main service panel. The heater should start warming up within two minutes. If it doesn't, contact a qualified electrician to inspect the thermostat and heater. Also, with the power to the circuit OFF, tighten all wiring connections and repair any frayed or broken wires.
