Troubleshooting Trane Furnace Problems: What to Know Before Calling a Service Technician

Keeping your home warm and comfortable with a reliable furnace is no small feat. It’s one of the most challenging aspects of owning a home. With so many different types of furnaces on the market today, combined with varying operating principles, you might find yourself confused when something goes wrong. If you have a Trane furnace, troubleshooting common issues might be slightly different than if you own another brand or model. But regardless of your specific model, understanding how your system operates will help you identify what’s malfunctioning and get it running smoothly again as quickly as possible. In this blog post, we will discuss some common trane furnace problems and how to diagnose them. To continue reading, please follow

Trane Furnace Problems and Their Causes

To begin, let’s go over the most common issues homeowners encounter with their furnaces, along with their causes. Armed with this information, you’ll be better equipped to troubleshoot your furnace and get it running smoothly again. Lack of Air Flow – To burn properly, gas-fired furnaces need a continuous supply of airflow. If this airflow is blocked for any reason, the furnace won’t be able to operate properly. Some of the most common reasons for a lack of airflow include: – A dirty or clogged filter – Filters are designed to capture dirt and debris, but will eventually become clogged and need to be replaced. If your filter is dirty or clogged, it will reduce the amount of air flowing through the furnace, preventing it from burning properly. – Incorrect size or type of filter – In addition to providing clean air, your filter also helps regulate airflow. If you’re using the wrong size or type of filter, it may restrict too much airflow, preventing the furnace from burning properly. – Blocked air ducts – If your furnace is installed in a room with an unvented duct system, it may have trouble drawing enough air from the room. This can occur when there is too much resistance in the duct system or if the ducts have become disconnected from their termination points.

Noisy Operation

If your furnace is making an unusually loud noise, it could be due to several things. Let’s take a look at some of the most common reasons for noisy operations. If you determine that one of these factors is responsible for the noise, you’ll know how to fix the problem. – Incorrect fan speed setting – If your furnace has a built-in fan, incorrect fan speed settings can cause it to make an unusual noise. Most furnaces have a built-in speed controller that regulates how fast the fan will operate. If this controller isn’t set properly, the fan will make a loud noise. – Too much or too little belt tension – If your furnace has a belt-driven fan, too much or too little belt tension can cause a loud noise. Adding too much tension to the belt will cause it to rub against the fan too aggressively, causing a loud noise. If there isn’t enough belt tension, the fan will spin too freely, producing a loud vibration as it bounces up and down against the shaft.

High Operational Temperatures

If your furnace is running too hot and shutting itself off, it could be due to several things. Let’s take a look at some of the most common reasons for high operational temperatures. If you determine that one of these factors is responsible for overheating, you’ll know how to fix the problem. – Incorrect thermostat settings – If your furnace is shutting itself off, but the problem isn’t related to the furnace fan, check the thermostat settings. If they’re not set correctly, the furnace will shut itself off to protect against an over-or under-temperature condition. – Dirty or clogged air filter – If your air filter has become dirty or clogged, airflow will be reduced. This will cause the furnace fan to work harder, thus causing the internal temperature to rise. – Dirty or clogged blower motor – If your blower motor has become dirty or clogged, it will have a hard time pulling air into the furnace. This will cause the furnace fan to work harder, thus raising internal temperatures.

Poor Combination of Controls

If your furnace isn’t operating properly, but everything appears to be set correctly, it could be due to a poor combination of controls. Let’s take a look at some of the most common reasons for poor control combinations. If you determine that one of these factors is the problem, you’ll know what to do. – Incorrect delay settings – Many furnaces have a built-in delay shut-off feature. This shuts the furnace off at a certain time after it starts. If the delay setting is set too short, the furnace will run longer than necessary, causing a dramatic rise in internal temperatures. If the delay setting is set too long, the furnace will shut itself off before everyone is out of the house, leaving your home unheated. – Incorrect operating mode – If your furnace is operating in the wrong mode, it will be less efficient at heating your home. It may also cause unnecessary wear and tear on the furnace motor.

Electronic Control Problems

If none of the other problems discussed above are causing your furnace issues, it could be due to an electronic control problem. Let’s take a look at some of the most common reasons for electronic control problems. If you determine that one of these factors is responsible for the problem, you’ll know what to do. – Excessive vibration – If your furnace control board is installed on an unbalanced or improperly supported surface, the vibrations from the furnace fan may damage it. This can cause it to malfunction. – Exposure to high temperatures – If your control board is improperly installed away from the airflow, it may overheat and stop working. This can also happen if the control board isn’t properly ventilated.

Conclusion

Keeping your home warm and comfortable with a reliable furnace is no small feat. It’s one of the most challenging aspects of owning a home. With so many different types of furnaces on the market today, combined with varying operating principles, you might find yourself confused when something goes wrong. If you have a Trane furnace, troubleshooting common issues might be slightly different than if you own another brand or model.
