Furnace Not Blowing Hot Air: Causes & Solutions
With the help of a skilled furnace repair technician in Lafayette, LA, you're likely to get your heating system back up and running in no time.
Depending on the cause of the problem, you may be able to fix the issue yourself. But you'll have to know what to look for first.
This blog will discuss the common reasons why a furnace stops blowing air.
Common Reasons Why Your Furnace Stops Blowing Air
The pilot light goes out.
Many furnaces require a pilot light. This flame stays lit at all times, and it ignites the gas burner when you need heat. If your pilot light keeps going out, you might need a furnace repair technician in Lafayette, LA to look at it for safety reasons.
It’s best not to try to fix this problem yourself because it would take more than your toolbox to make sure it operates safely.
Thermostat Problems
A thermostat sends a message to the furnace when the temperature in your house drops below a certain level. If it fails to send the message because the battery had gone bad, someone changed the setting, or the fan is set to “on”, you won't start getting warm air.
In some cases, the problem could be solved by simply setting the temperature right or using a new battery to make your unit work again.
The blower belt has come off.
The blower belt transfers the motor's energy to the fan, so if it breaks or comes loose, your furnace won't blow air through the ducts. If you can't seem to get your belt back on, call a technician. You could also have an issue with the pulley or another part of the blower mechanism.
Old & Ditry Flame Sensor
If you have an older furnace, it might use a flame sensor to determine whether or not the pilot light is lit. If this part is dirty or damaged, your furnace won't generate consistent hot air because it will cause the burner to shut off.
Getting rid of the grim may fix the problem. No matter how small the job seems, you can contact a furnace repair technician in Lafayette, LA for help.
The burner is clogged with dirt.
A clogged burner will prevent the furnace from getting sufficient fuel to heat your space. The fan, however, may still continue blowing air. But in this case, the air you're getting won't be warm. A little clean-up may also fix this issue.
Filthy Filters
Problems with low airflow may result from a dirty air filter. When the filter is caked with dirt, the air won't be able to pass through. The solution, just like with other problems, is simple - clean it.
But some types of filters are better to be replaced. So check yours and know whether it's a disposable or washable type.
