You may have a broken thermostat wire. Disconnect the wires from the thermostat and please note what colors are hooked to which terminals. Cross the R and W wires and see if your heating system turns on. If it does not, you have a broken wire or bad connection at the heating system. If it does start, you have a bad thermostat or bad connection at the thermostat.
