When your heating system in Kenilworth, IL doesn’t kick on, you need to find and resolve the underlying problem promptly. Let’s take a look at five common issues that can prevent your furnace from igniting normally.
Wrong Thermostat Setting
When your furnace doesn’t ignite, inspect its thermostat first. Make sure its fan is on the “Auto” setting instead of “On.” If it’s on “Auto” and still won’t ignite, a technician may need to recalibrate or replace the thermostat.
Tripped Breaker
If the thermostat doesn’t ignite normally, you can also check the furnace’s circuit breaker in your home’s electrical panel. You might have a tripped breaker. You can also reset the breaker by turning it off and then back on again.
Ignition Sensor or Thermocouple Malfunction
Older furnaces typically have thermocouples that detect heat from the pilot light. Newer furnaces have ignition sensors that detect if the burners fail to ignite. If the thermocouple or ignition sensor malfunctions, your furnace won’t ignite like normal and will require professional repairs.
Gas Mixture Imbalance
An imbalance of the gas mixture will cause problems like a delayed or failed ignition in your furnace. This type of ignition malfunction requires you to hire an HVAC technician in Kenilworth, IL to repair it. You can minimize this problem from occurring by ensuring your furnace undergoes seasonal maintenance.
Gas Leak
A gas leak will disrupt normal ignition in your furnace. If your carbon monoxide detector alerts you to a gas leak or you notice a gas odor in your home, turn off your furnace and then leave the house immediately. Open the windows, call the gas company or fire department and hire a licensed HVAC technician to find and repair the gas leak.
