Thermostat
Your furnace may not be turning on due to another system: your thermostat. It is possible that your thermostat may have reset, lost its programming, or be on an incorrect setting. Set your thermostat to heat and lower the temperature by 10-15 degrees to attempt to turn your furnace back on.

Blown Circuit Breaker
Your furnace requires power to run, if you have a blown circuit breaker this may be the reason why it is off. Check your home breaker box for a protentional blown circuit breaker, flip it back and forth and make sure it stays on the “on” position.

Dirty Air Filter
Many homeowners neglect changing their air filter within the required time frame which can result in many HVAC issues. Your furnace may not be turning on because your air filter is simply clogged. A safety feature in your furnace may prevent your furnace from turning on to avoid any damage. Make sure you are replacing your air filter 90 days to avoid running into this problem.
