Trane XR90 Light Manual
One of the best features of the XR90 is the color and speed specified error codes. This feature tells you through a specific sequence the exact problem with the Trane XR90 system.
There is a red light present on your trane. The pattern through which this red light flashes can identify what’s wrong with your trane.
If the red light flashes slowly then it indicates that there is no call for heat. When it flashes rapidly then there is a call for heat.
Now if the red light is off then there is a power outage. Continuously on red light indicates that the circuit board needs replacement.
To make it easy for you to understand the specific codes behind each problem, we’ve compiled a table.
|2 Flashes||External Lockout|
|3 Flashes||Faulty Pressure Switch|
|4 Flashes||Troubled Limit Device|
|5 Flashes||No Flame|
|6 Flashes||Poor Grounding|
|7 Flashes||Gas Valve Error|
|8 Flashes||Low Flame Signal|
|9 Flashes||Faulty Igniter|
Now that you know what each of the signals means, let’s get into the troubleshooting part.
Troubleshooting a Trane XR90
Troubleshooting a Trane XR90 can seem daunting at first. However, by going through each of the causes you can properly identify the explanation behind your trane not working.
Make sure to serially check each of the problems thoroughly. Only after being completely sure that you’ve identified the problem move on to the solutions.
Sometimes your thermostat can fail to properly work if it’s damaged. So thoroughly check your thermostat for any sort of damage. In this case, you may need to troubleshoot the wall heater.
Sometimes there may be a lack of power in the thermostat of the furnace. If you see that your display screen is either blank or flickering then your thermoset may lack power.
Unfortunately, the only solution to a faulty thermostat is to replace it with a new one. You can easily find thermostats in your local hardware shop.
Faulty Circuit Breaker
Sometimes due to a lack of appropriate power, your furnace may fail to work. In this case, you need to check your circuit breaker as it supplies all the power needed for your furnace.
A fault in your circuit breaker can cause a plethora of problems. The problems of monitor heater are due to this reason as well.
Investigate your circuit burner by switching it off and then turning it on again. This will recalibrate your system.
If switching it on and off doesn’t fix the issue then your circuit breaker may have severe problems. That’s why it can’t supply appropriate power to the furnace.
To fix your circuit breaker you need to contact a mechanic. After assessing your circuit breaker the mechanic will decide whether it can be fixed or not.
The mechanic will fix the circuit breaker if the problem is mild. However, a malfunctioning circuit breaker may need to be replaced with a new one. Here are a few of our suggestions for circuit breakers.
One of the most common problems every furnace owner faces is poor airflow or heating. It can happen due to clogged filters.
The filters inside your furnace collect dirt and debris over time. If this dirt build-up continues to grow then your filters may get clogged.
To see if there’s any dirt build-up, take out the filter from the furnace. If you see that there is dust build-up then properly clean it.
By using water and a gentle scrubbing brush you can get rid of all the dirt present on your filter.
Make sure to inspect your filter from time to time for dirt and debris buildup. It’s best to check the filters every 6 months. However, inspecting it annually will do the job.
Sometimes due to a faulty burner or igniter, your furnace may fail to provide heat. If you suspect that this is the case then check your burner for any sort of damage.
This type of problem also comes up during troubleshooting the nordyne furnace. So you can see how common this problem is among furnaces.
The only solution to a faulty burner is to replace it. Burners can get damaged over time due to stress. So simply replacing it will fix the issue.
In general, you should replace your burner every 3-5 years. Depending on the humidity the time will either increase or decrease.
Turned off Gas Valve
There is a concern about heat going out with your trance furnace. This happens when your gas valve is not on.
This problem may sound simple to you but it’s more common than you think.
Simply turning on the gas valve of the trane furnace will produce heat.
Gas leaks are one of the most dangerous problems of a furnace. Occasionally the parts of the furnace get damaged and start to leak.
The fleeting smell of gas coming from your furnace is normal. However, if you sense a strong lingering smell of gas throughout your house your furnace may be leaking.
The gas that leaks out of your furnace is carbon monoxide. Carbon monoxide poisoning occurs if you are exposed to it for a prolonged period.
In case of a gas leak, evacuate the house immediately and call professionals to fix the furnace for you.
You should also install carbon monoxide detectors throughout your house. These can detect the level of carbon monoxide in the air and can warn you in case of a gas leak.
These are all the ways you can troubleshoot your Trane XR90 furnace.
