  • Check whether the thermostat requires fresh batteries. This is what can cause a furnace to stop working. 
  • In case the system is hardwired, the breaker is tripped or not? 
  • Check the setting of the thermostat. Is the present thermostat in and the heat mode put on? Is the final temperature set above the current temperature of the room in order to initiate the heating cycle?  

The circuit breaker has flipped 

In case the circuit breaker has flipped, this can cut off the power traveling to the heating components of your system. In case your furnace ceases to function, you should consider checking the system’s circuit breaker and reset the tripped breakers. 

In case the issue becomes repetitive, then there is a problem that keeps on occurring. You should consider calling an HVAC technician in order to diagnose, hence solving the problem.

This can lead to problems such as overheating which could cause the whole system to go off as the safety button or switch ensures the unit is switched off whenever the high temperatures have been reached. 

In case the filter is covered wholly with debris ensure that you have replaced it. Give it some humble time to cool off and come back to see if the furnace relights. 

The access panel is not fully on

  • Clear the items that are stored around the furnace. Keep them six feet away. 
  • Check the system’s air filter and in case they are dirty you should be in a perfect position to replace them. 
  • Ensure that all the vents in your place have been opened and unblocked to allow air circulation to take place. 

Burners are dirty 

The burners often collect rust and dirt from time to time thus reducing the heat output. You shy to be able to clean your burners  following the process down below: 

  • Ensure that the electricity at the breaker box is switched off and also close off the gas valve that leads to the furnace. 
  • You should be able to remove the access panel towards the combustion chamber and also remove the small panel that encloses the system’s burner chamber. 
  • You should ensure that you have removed the metal clips in order to detach the burners. 
  • By using a soft brush and a vacuum, you should be able to clean off the debris away from the surface of the burner. You should blow the compressed air to remove the debris, turning and tapping the system’s burner in order to assist in detaching the debris.
