    Could be a defective circuit breaker, loose connection in the circuit, etc.

    If you do not have the knowledge and equipment to work on wiring, need to call in an electrician to troubleshoot the problem.

    I agree with TK but think you really need an HVAC repairman. Today's furnaces and tstats are more like computers and need a technician. Many furnaces will trip limiter switches if power has been killed while the furnace was firing.
