Could be an electrical fault in the thermostat, but my 100:1 odds-on favorite guess would be low batteries. Some brands just show a LoBat or similar optical code, others have an audible alarm (some Vivent and Xfinity ones, at least) - a clicking, a beep, etc. And once the alarm runs a cedrtain amount of time the power gets too low to power the alarm, so all you hear is a minor electrical "click" - smae thing happens on security alarms when the backup battery goes dead.


Replace batteries - checking when you do that they have not leaked out and corroded the contacts, or in worst case (this happened to me once when I made the mistake of putting in Duracell rather than bunny batteries) the battery acid from a leaking battery can get into the circuitry and ruin the entire thermostat.


One other possibility - the thermostat is set for normal demand temperature settings so it wants to turn on, but the control switch (usually a slide switch) has been moved to A/C or Fan, so the thermostat is trying to activate but is not getting a connection to the furnace. Ditto can happen if a wire to/from the furnace/thermostat has broken or come disconnected.
