In this blog post, we will study in detail the reasons and solutions for why a furnace is not blowing hot air.
Common Reasons Why Furnace is not Blowing Hot Air
To troubleshoot why your furnace is not blowing hot air, you need to understand the common reasons behind it.
Dirty Air Filter
A clogged air filter can stop hot air from flowing through your furnace, reducing airflow and affecting performance.
This is because a dirty filter doesn’t let enough air pass over the heat exchanger. This can overheat the system and cause it to shut down for safety.
To avoid this, change your filter every 3 months – or more often if you have pets or allergies.
A dirty filter also makes your furnace inefficient. This means you’ll be cold and your energy bill will be higher.
Plus, dirty filters let pollutants like pet hair and dust mites circulate in your home, affecting indoor air quality.
Thermostat Setting
Maintaining the right thermostat setting is essential to make sure your furnace blows hot air.
Incorrect calibration can mean too much or too little heat, leading to discomfort and expensive bills. Keep it at or below 68 degrees Fahrenheit to save energy.
Your furnace might blow cold air if you don’t adjust the airflow settings to your home’s size and insulation.
A dirty air filter can cause poor performance and cool air instead of hot.
Pilot Light
One of them could be the pilot light. This small flame is important for igniting the burners and heating your house. If it goes out, then expect your furnace to underperform.
You can usually spot the pilot light near the burners, behind a removable panel. Check for a blue flame.
If it’s not lit, try to relight it according to the manufacturer’s instructions. Sometimes the thermocouple, which detects if the flame is on, may be the cause of the pilot light not staying lit.
Checking your furnace regularly and maintaining it will help avoid problems with the pilot light and ensure it runs smoothly throughout its lifespan.
Flame Sensor
The Flame Sensor is a key part of your furnace. It stops gas leaks and lets the burners light up.
It spots the flame from the pilot light or main burner and tells the furnace control board to turn on the blower fan so warm air comes out.
Here are some facts about the Flame Sensor:
- Purpose: To see if there is a flame
- Location: Near Burners
- Detection Type: Infrared Signal
- Maintenance: Clean with Fine Grit Sandpaper
A bad or dirty Flame Sensor can stop your furnace from making heat and cause cold living conditions. It can also cause damage to your furnace, leading to costly repairs or replacements.
Fan Limit Switch
The Fan Limit Switch is a major part of your furnace which regulates the fan’s temperature. It’s set to switch on/off to manage the furnace’s heat.
When your furnace is switched on and cold air comes out instead of warm, this could suggest issues with the Fan Limit Switch. It might not be working correctly, leading to no hot air circulating.
It’s vital to check that all sensors are connected and working, as malfunctions can alter the air temperature.
Gas Valve
The Gas Valve is key for the furnace’s operation. It controls gas flow to the burner. When it’s not functioning right, no hot air reaches your home.
Here’s what to look out for:
- Clogged pilot – No heat.
- Corroded valve – Weak flame.
- Broken igniter – Inaccurate temperature.
Older furnaces can also struggle with ignition due to dirt or worn parts. Regular maintenance and cleaning can keep your furnace running smoothly.
Protect your family and avoid repairs. Get a professional tune-up every year. If you spot any issues, act fast!
Overheating
Furnace overheating can be a sign of a malfunctioning system. High temperature can harm the internal components and reduce efficiency.
Listen out for strange sounds or smells coming from the furnace, or if it shuts down suddenly. It’s time to call a professional.
Dirt and debris build-up in the air filter is often the cause of overheating. This makes the furnace work harder, leading to higher temperatures and inefficiency.
Replace the air filter regularly, as per manufacturer’s instructions.
High Limit Switch
Is your furnace not blowing hot air? The High Limit Switch could be the cause. It’s a safety device that turns off the furnace when it gets too hot, to prevent fires. When it senses high temperatures, the burner is shut off.
The following table shows more details about the High Limit Switch:
| High Limit Switch |
| Location: Near heat exchanger or blower drive |
| Function: Prevent overheating & fires |
| Symptoms: Furnace starts but no warm air; frequent cycling |
The High Limit Switch protects you from potential hazards – like fires caused by overheating.
If your furnace starts but no warm air is coming out, or it cycles on and off often, it may be the High Limit Switch.
