Potential Causes of a Goodman Furnace Not Igniting
There are several potential causes of a Goodman furnace not igniting, including:
Faulty Ignition Control Board
The ignition control board is responsible for controlling the ignition process and ensuring that the furnace starts up properly. If the ignition control board is faulty, it can prevent the furnace from igniting.
Faulty Thermostat
The thermostat sends a signal to the furnace to start heating when the temperature inside the home drops below the set point. If the thermostat is not functioning properly, it may not send the proper signal to the furnace, causing it to fail to ignite.
Malfunctioning Hot Surface Igniter
The hot surface igniter is responsible for generating the spark that ignites the gas in the furnace. If the hot surface igniter is not functioning properly, the furnace will not ignite.
Clogged Air Filter
A clogged air filter can restrict the flow of air to the furnace, causing it to overheat and shut down. This can prevent the furnace from igniting.
Malfunctioning Flame Sensor
The flame sensor is responsible for detecting the presence of a flame in the furnace. If the flame sensor is not functioning properly, it may prevent the furnace from igniting or cause it to shut down unexpectedly.
Any of these issues can cause a Goodman furnace not to ignite. To determine the root cause of the problem, you will need to perform some basic troubleshooting steps and, if necessary, consult with a professional HVAC technician.
Troubleshooting Steps
There are a few basic troubleshooting steps that you can try if your Goodman furnace is not igniting:
Check Thermostat Settings
Make sure that the thermostat is set to “heat” and that the temperature is set to a comfortable level. If the thermostat is not set correctly, it may not send the proper signal to the furnace to start heating.
Check and Replace the Air Filter
A clogged air filter can restrict the flow of air to the furnace, causing it to overheat and shut down. Check the air filter and replace it if it is dirty or clogged.
Clean the Flame Sensor
The flame sensor is responsible for detecting the presence of a flame in the furnace. If the flame sensor is dirty or covered in debris, it may not function properly. Clean the flame sensor by gently brushing it with a soft cloth or a small brush.
If these troubleshooting steps do not resolve the issue, it may be necessary to call a professional HVAC technician to diagnose and repair the problem.
