Inspect The Electrical Circuit and The Heater Switch

In this troubleshooting step, you must inspect the furnace control button near your heating system. It is because there are odds that it may have gotten switched off by accident, leaving you freezing. Also, if you notice that your heater button is off, try to switch it back on. 

Despite this, if the system does not run, move to the main power opening. Check to see if the circuit breaker or toggle control is on. Furthermore, you should ensure that the furnace circuit remains turned on if your breaker box is accurately marked.  

Examine The Heating Filtration System
