Trane Furnace Not Heating. Does it seem like your furnace turns on yet you do not feel any heat in your home?.
A large number of Birmingham residents experience this problem because their heating system may be malfunction.
Fortunately, there are many potential causes, and simple troubleshooting steps can help solve the issue.
If the issues are not simply fixed, seek out professional Services to determine the cause of your heating problems.

The following are some problems with Trane furnaces when they are not heating.
Problems With Air Flow
To maintain the efficiency of a furnace, it is necessary for it to have a sufficient volume of airflow.
Due to the change in weather patterns throughout the year, the furnace may need a clear path free of obstructions at any time of the year if it draws air from outside.
In just the same way that a foggy night at sea dims visibility, small objects in your furnace’s path or clogged vents will reduce airflow and consequently hamper the furnace’s ability to distribute heat throughout your home.
Issues With Pressure Switches
When there is sufficient airflow through the burner, the pressure switch closes. If you don’t have enough air coming into the burner, it might not close when the proper amount of heat is present, and ignition will stall.
To check if your pressure switch is working, use a multimeter to test for continuity in the wire connector by measuring across leads on both sides to see if it makes a circuit with that measurement.
If not, then your pressure switch might be broken, or some other part of your electrical system may be faulty. Either way, replace your pressure switch to continue starting your furnace properly.
Assemblies For Gas Valves
An opening in the gas valve allows the flame inside to come out and heat the house. If there is a problem with the gas door, our furnace wont is able to warm up in case it’s broken.
We better use a multimeter to see if there’s continuity between that piece of metal or plastic and another one because it should let electrical current flow through if they are connected. So let’s get down to business.
Problem With Wall Thermostat
The wall thermostat has the ability to control the power supply to the furnace through electrical contacts.
In the unlikely event that there are no continuity problems with the thermostat, then it must be replaced.
Customer should keep in mind when they purchase a new part that there is more to it than just being off by a few degrees when it comes to using this great appliance.
Limit Switch For Flame Rollout
Flame rollout switches monitor the heat surrounding the burners. In a properly installed and maintained gas-fired furnace, the flame rollout switch is rarely defective.
If the furnace continues to operate after the burner assembly has been shut off or if it shuts off even though all of the burner parts have not cooled off.
You have to replace this part because there are probably several other things wrong with it, like a lack of ventilation, an inadequate supply of air for the fuel atomization process, etc.
Also, note that most of these problems could be avoided by taking your furnace temperature gauge reading twice a day so as to avoid potential overheating situations at all times.
Inducer Motor For Drafts
The draft inducer motor draws air into and out of the heat exchanger, where indoor air is heated.
Whether or not the furnace shuts off depends on whether there’s enough air passing through the fan; in order for combustion to take place, there has to be sufficient flow.
When the fan reaches a certain pressure, the pressure switch closes a switch to tell the electronic control board that there is enough airflow. If the pressure switch fails to close properly, the furnace won’t start.
Either there is not enough airflow over the exchanger, or there is not enough voltage reaching the control boar. Before assuming that something is wrong with your draft inducer motor, check both.
Defective Flame Sensor
Flame sensors monitor the burner, and if there is no flame detected, they turn off the voltage to the gas valve, which prevents the furnace from heating up.
It is possible for a dirty or faulty flame sensor to fail to detect a pilot light that is burning.
If you are experiencing false malfunctions with your flame sensor, cleaning it with a fine abrasive pad should be able to correct your issues. If your furnace still doesn’t heat, you’ll want to replace the now-defective flame sensor.
Faulty Igniter
Igniters are responsible for creating the spark that will light up your burner or pilot light. If you see that your igniter is cracked, chances are it won’t last long, and some parts inside may not be working.
Igniters also get worn down over time and should be replaced periodically to ensure a heat source remains functional.
You can use a multimeter to test the continuity of any component in your gas furnace, but with an igniter, you’ll want to try pushing on it.
If you feel discomfort when touching your gas igniter, then this component is likely faulty and requires replacement.
