Why Won’t Your Furnace Ignite in Your Slidell, LA Home?
A malfunctioning furnace makes your home cold and uncomfortable. Possible causes include an ignition issue, which is one problem homeowners in Slidell, LA, might experience during winter. Let’s look at reasons a furnace might fail to ignite.
Flame Sensor Issues
A flame sensor is an important safety feature that prevents gas from leaking into your home. When the gas valve opens, if the flame sensor does not detect a flame within a few seconds, it sends signals to the control board to turn off the furnace to prevent gas from leaking into your home.
With time, the flame sensor may become dirty or malfunction. Consequently, it sends wrong signals to the control board, preventing your furnace from igniting. Our service technicians clean and repair furnace flame sensors.
The thermostat communicates desired temperature settings to the furnace, sending signals to it through a set of wires. Any damage to the thermostat will prevent proper transmission between the thermostat and the furnace.
If the thermostat isn’t working, it can’t tell the furnace when to cycle on. However, the issue may be as simple as forgetting to set your thermostat to heat mode. Checking the thermostat’s setting is a wise first step.
A Dirty Furnace Filter
A furnace filter traps pollutants such as pet fur, pollen, and debris, preventing them from contaminating the system. Over time, pollutants build up, clogging the filter and making it difficult for air to pass through freely.
Furnace burners will not ignite when there is insufficient airflow. Follow the instructions for your system’s filter, and be sure to clean or replace dirty filters as directed.
Gas Line Issues
You may have forgotten to turn on your gas supply, so the system cannot ignite. Also, depending on the location and make, someone can accidentally close the valve. Check that the furnace valve is set to “on.”
