Answer: Why Does My Furnace Click But Not Ignite?
When you hear clicking sounds from your furnace but the burners do not light, the ignitor is trying to ignite the gas but something is preventing it. The most common reasons are: the ignitor is glowing but not reaching the temperature needed for ignition, the gas valve is not opening due to a control board or solenoid issue, the flame sensor is too dirty to detect the flame, the gas supply is interrupted (check if other gas appliances are working), or the control board is not sending the correct timing signals. Avoid repeatedly cycling the furnace — this can flood the combustion chamber with unburned gas, creating a safety hazard.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
