Possible Causes and Solutions for Heater Blowing Cold Air
Here are some of the most common culprits – and solutions – for a heater that’s blowing cold air.
Check Your Thermostat Settings
Before calling for service, double-check that your thermostat is set properly. Make sure it’s tuned to “heat” mode and the temperature is set higher than the current room temperature. Sometimes the problem is as simple as accidentally bumping the thermostat or forgetting to switch modes with the seasons.
If adjusting the thermostat doesn’t fix the issue, it’s time to investigate other potential causes.
Examine the Pilot Light
One possibility is that the pilot light has gone out. The pilot light provides a flame that ignites the gas burners in your heater. If this small flame goes out, the burners can’t operate.
Examine the pilot light chamber and relight it if needed.
If the pilot light doesn’t stay lit, there may be an issue with the thermocouple or gas line supplying the pilot. Our technicians have the expertise to inspect these components and get your pilot light working properly again.
Check for Blockages and Broken Parts
Another common problem is a blockage in the heater’s air intake or exhaust vents. Dust, lint, and other debris can build up and prevent proper airflow. Make sure both the intake and exhaust vents are clean and unobstructed.
Faulty or broken blower fans are another possibility. If the fans aren’t spinning to circulate air across the heating elements, you’ll end up with cold-blowing air. Our techs can test the fans and repair or replace broken parts.
Consider Problems with Electrical Wiring
Heaters rely on proper electrical connections to operate the pilot light, blowers, and other components. Loose wiring or electrical shorts can prevent the heating system from firing up correctly.
Don’t mess with your heater’s internal wiring yourself unless you’re highly experienced.
Our expert technicians have the skills to troubleshoot electrical issues safely.
Check the Condition of the Burners
The gas burners inside your heater need to ignite and burn properly to heat your home. Dirty or damaged burners may fail to light or have obstructed flames, preventing adequate heat production.
Our team can remove and inspect the burner assembly, clear any debris, and replace damaged parts. Having us service the burners periodically helps keep them working their best.
