Trane furnaces are designed to provide heat to homes and businesses. They are also very reliable and efficient.

If you have a Trane furnace, then you should know how to troubleshoot it.

How To Troubleshoot A Trane Furnace

A Trane furnace is a type of forced-air heating system. This means that they force hot air into your home or building through ductwork.

The air circulates around your house or office, warming up the space.

What Is A Trane Furnace?

Trane is a brand name; they produce some exquisite gas and oil furnaces, keeping folk warm all across the nation.

However, as great as they are, they’re not always perfect devices, nor are any kind of furnaces really.

You should call an HVAC technician if you smell gas or if there are strange noises coming from your gas furnace.

Gas furnaces are dangerous, but although heating systems should be repaired by licensed professionals, you can have a go at troubleshooting your issues.

Bear in mind, though, that repairing them improperly can lead to dangerous leaks or an explosion.

Furnaces can also shock you during wiring work, so always consult a licensed heating specialist to complete the actual repairs.

Common Problems

Here are some common problems that you might encounter with your Trane furnace and how to fix them.

No Heat

If you do not feel any warmth in your home or business when you turn on your Trane furnace, then there could be several reasons for this problem.

First, make sure that the thermostat has been set correctly. It should be set at least 10 degrees higher than the temperature outside.

If the thermostat is set too low, then the furnace will not run long enough to warm up your home or office.

Also, make sure that the blower fan is running properly. Check the filter inside the unit as well.

You may need to replace the filter if it becomes clogged.

Too Much Heat

An overheating furnace is almost always caused by one thing, and one thing only… restricted airflow.

Granted, it’s your furnace’s job to get hot, but that heat needs to be controllable.

The internal components of the unit can only deal with so much thermal punishment, and if they aren’t receiving any air, they will just keep heating up until they give up the ghost.

Low Airflow

If you notice that the airflow coming out of the vents in your home or office is weak, then there could be a number of reasons for this.

One possibility is that the filters inside the unit are dirty. Another possible cause is that the blower fan motor is worn out.

To check these things, simply open the door of the unit and see if the air is blowing freely.

If it isn’t, then you may want to clean the filters and change the blower fan.

Blowing Hot Air Outside Your Home

This is another common problem with Trane furnaces.

When the blower fan is working properly, it pushes air throughout the entire home or office.

However, sometimes the air blows only part way through the ducts.

In order to correct this issue, you will need to adjust the position of the blower fan.

Simply move the blower fan closer to the wall where the ducts meet.

Burning Odors

This is one of the most common complaints about Trane furnaces.

If you smell burning odors while using your Trane furnace, you will first need to determine whether the odor is coming from the furnace itself or somewhere else in your home.

To find out which room smells like smoke, simply open all windows and doors in your home or office.

Then close each window and door until you find the source of the odor.

Furnace Not Working Properly

If you have a Trane furnace installed in your home or office, then you will probably need to call a professional heating repair technician to help you diagnose the problem.

A qualified service technician can tell you what type of repairs are needed by looking at the parts of your Trane furnace.

This way, they can quickly identify the problem and get started fixing it right away.

Furnace Leaks

Leaking gas lines can damage your property and even put you at risk.

If you suspect that your Trane furnace is leaking gas, then you should contact a professional heating repair technician immediately.

They can inspect the area around the furnace to determine the source of the leak.

If you suspect there might be a gas leak, it’s essential that you shut off both your gas and furnace, and, if possible, vacate the property.

Furnace Repair Costs

Furnace Not Working Properly

The cost of repairing a Trane furnace depends on how old the equipment is.

Older models tend to be more expensive to fix than newer ones.

You also need to consider the amount of time it takes to complete the job.

It may take longer to replace a faulty blower motor than to install new filter screens.

Furnace Installation Cost

The installation cost of a Trane furnace varies depending on the size of your home or office.

For example, installing a small furnace in a two-bedroom house costs less than $1,000.

On the other hand, installing a large furnace in a four-bedroom home costs between $2,500 and $3,000.

Furnace Maintenance Cost

Trane furnaces come equipped with an annual maintenance plan.

This means that you pay a monthly fee to keep your furnace running smoothly.

The price of this plan depends on the size of your furnace. For example, a 30,000 BTU furnace costs approximately $30 per month.

Furnace Replacement Cost

Trane furnaces last for years. As a result, replacing a Trane furnace can save you money over the long run.

However, if you choose to replace your current model, make sure that you buy a high-quality replacement unit.

Furnace Warranty

Most Trane furnaces come with a warranty.

This means that Trane will cover any problems caused by defective parts during the first year after purchase.

After the first year, you will need to pay for any repairs yourself.

How To Fix A Trane Furnace

A Trane furnace is a very efficient heating system that is used by many people.

It flashes green lights to let you know if something is wrong with it.

The thermocouple sends signals to the control board telling it what temperature to set.

Red flashing lights mean there is a problem with the sending unit.

You need to check the wiring and make sure everything is working correctly.

To troubleshoot your Tran gas furnace, open and close the blower door until a small flashing red light indicates the connection is fully sealed (this is a common problem).

Don’t rely on your Tran gas furnace alone when it comes to repairing problems.

Instead, call an HVAC professional for help.

Consider investing in an HVAC maintenance plan so you’ll avoid surprise repairs down the line.

When the gas valve is blocked, the gas won’t flow out of the tank. There is a warning sign on the top of the tank.

A green light flashes, indicating that there is a problem. The number of flashes indicates the severity of the problem.

External lockout means that the gas valve is blocked.

Trane Xr80 Troubleshooting

Greenlight speed is the most important thing when maintaining a furnace.

The faster the green light flashes, the better condition your furnace is in.

If the green light is constantly flashing, then the furnace is probably not working correctly.

Your furnace may be off or not receiving power. Your furnace control board may also need replacing.

The flashing red light means that your furnace is malfunctioning. You should check if there is any damage to your furnace.

If your red light is flashing slowly, this means there is no call for heating.

If your red light is flashing fast, this means there is a call for heating.

If your red light is constantly on, this means the circuit board needs replacing.

If your red light is continuously off, it means the power of your furnace needs checking.

You should contact a repair technician to fully inspect and repair the problem.

Problems With The Thermostat

You need to check if there are any electrical problems in your house. You also need to make sure that the thermostat works properly.

You can use a circuit breaker to reset your electrical system. Turn off power to your circuit breaker first, then turn it back on.

If your circuit breaker doesn’t work when you flip it back on, contact a professional electrician or furnace repairman.

Trane Furnace Troubleshooting

Check your thermostat first before calling a professional. Don’t forget to turn it back on.

Set your thermostat to heat at least 5 degrees above room temperature.

Your furnace works by making heat, then blowing that hot air through all of your vents to raise the temperature.

If you feel like your house is still cold, but your furnace is running, make sure all your vent openings are completely open.

Clean or replace your furnace filter if you think it may be blocking the airflow.

First, locate the furnace filter. Then make sure the furnace is completely turned off by unplugging it.

The filter should be in a place that is easy to reach. A furnace filter should always be clean. Never operate your furnace without a filter!

If you see dirt or debris on your filter, change it right away.

Rinse your filter with water, then let it dry completely before returning it to your furnace.

If you have a permanent filter, rinse it thoroughly with water and allow it to air-dry completely before replacing it in your furnace.

You need to turn off the switches on the furnace first before checking the breaker panel.

If the furnace isn’t working, then there could be a problem with the wiring. Contact an HVAC professional.

Older furnaces had blue flames that were always visible.

These days, newer furnaces use electric ignitions that turn on only when needed.

So there isn’t a blue flame, but you’ll still need to check the burner openings. Dirty burners could cause yellowish flames.

Cleaning out the burners and checking them for debris can prevent problems.

To relight the pilot light, turn off the switch and wait a few seconds before turning it back on.

If you have a newer furnace, check the gas valve. Make sure it’s on and supplying gas to your pilot light.

Final Thoughts

If you want to keep your furnace working well for many more years, call an HVAC technician as soon as possible.

They can help you identify potential problems and recommend solutions.

In addition, they can provide regular maintenance services, so you don’t have to worry about fixing things yourself.
