What to do if my Honeywell Thermostat has no heat?

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.
