pressure switch error on trane furnace

When it comes to your home’s heating and cooling system, you want to make sure it is running as efficiently as possible. If your thermostat is set to 73 degrees, but the temperature in your home never gets that low, there’s a good chance that you have some issues with either the pressure switch or the pressure switch error. Let’s start with the pressure switch error first. This is a common issue that occurs when there is something wrong with your furnace’s pressure switch. The pressure switch reads whether or not there is enough pressure in the exhaust pipe for it to operate properly, which means it helps protect your system from overheating. When this little device detects excess pressure, it will trigger a safety response from the furnace by turning it off until the excess air has been released and a normal level of pressure has been restored.

Trane Pressure Switch Error Codes

While each furnace’s error codes may vary, some are pretty common when it comes to pressure switch problems. If you notice that your pressure switch is triggering an error code, make sure to call in a professional to diagnose the issue. The following are some of the most common pressure switch error codes: – ER-900: This means there is a general error that could be caused by several things, including a mis-set thermostat, a faulty gas/electrical connection, a dirty filter, or even a broken sensor. – ER-1000: This error usually means that there is a faulty pressure switch. – ER-2000: This error could mean that the pressure switch is mis-set, or that there is a problem with the fan motor.

What Causes a Pressure Switch Error?

Several different things could cause your pressure switch to trigger an error, including a clogged filter, a faulty fan motor, or a faulty sensor. If you have recently had work done on your furnace, it is important to make sure that any contractor that you hire to fix any issues ensures that the pressure switch error is fixed as well. There is also the possibility that a faulty pressure switch is a result of simply needing to be replaced. If you’ve had your furnace for a while and the pressure switch has never given you any trouble, it may be time to replace the device.

How To Fix a Trane Pressure Switch Error

Fortunately, most pressure switch errors can be resolved by simply cleaning the filter and cleaning out any debris that may have clogged up the fan motor. In some cases, the sensor may need to be replaced. If your pressure switch error code is not resolved after cleaning out the filter and/or replacing the sensor, you may need to replace the pressure switch entirely. If you’ve determined that replacing the pressure switch is the best course of action, you may want to consider contacting a professional HVAC contractor. Thankfully, most pressure switch errors are easy to fix. If you are unsure about which parts of the furnace need to be cleaned, it is best to call a professional and let them take care of the job. They will know exactly where dirt and debris may have built up and will be able to clean your system thoroughly.

How to Fix a Trane Furnace With A Pressure Switch Error

If you do have a pressure switch error, it is important to have it diagnosed as soon as possible. The longer a pressure switch error is left unattended, the higher the risk that your furnace will break down entirely. With that in mind, make sure to call a professional if you notice a pressure switch error code on your furnace control board. If you have an older furnace, a pressure switch error could be the first symptom of a larger problem. To protect your investment, make sure to have the issue inspected and resolved as soon as possible. If your furnace has a pressure switch error, you may need to replace the device entirely. If you are not comfortable attempting the repair yourself, you can always call a professional to come out and inspect the issue for you.

Resetting the Trane Furnace Electronic Module

If you notice a pressure switch error code on your furnace and the error is not resolved after you have cleaned the filter and replaced the sensor, you may want to attempt to reset your furnace’s electronic module. There are a few different ways to reset your furnace. You can either unplug the unit for about 20-30 minutes and then plug it back in, or you can manually try to reset the circuit breaker.

Checking the Exhaust Piping

If you’ve tried resetting the circuit breaker, cleaning the filter, and replacing the sensor, you may want to inspect the exhaust piping. The pressure switch is designed to shut the furnace down if there is too much pressure in the exhaust piping. In some cases, the pressure switch may mistake the pressure in the piping for excess pressure in the system, which is why checking the exhaust piping may help resolve the error code. If you’ve checked all of the above and you’ve determined that the pressure switch is faulty, you will need to replace the device. If you are uncomfortable replacing the pressure switch yourself, it’s best to call a professional.

Conclusion

A pressure switch error could be caused by several different issues, including a clogged filter, a faulty fan motor, or a faulty sensor. If you have recently had work done on your furnace, it is important to make sure that any contractor that you hire to fix any issues ensures that the pressure switch error is fixed as well.
