This is Why Your Tesla’s Fan Keeps Running


This is Why Your Tesla’s Fan Keeps Running

Electric vehicles may not have reached widespread adoption quite yet, but for those who can afford it, a Tesla is likely high on your list. If you have recently purchased a Tesla, especially if you do not have any prior experience with electric cars, you probably have a few questions about all the fan sounds the vehicle makes, or other seemingly odd behaviors that the car has.

This is why your Tesla’s fan keeps running.  The most common reasons for Tesla fans to be running include:

  1. Automated Climate Control is Activated
  2. Battery Heat Level Maintenance
  3. Tesla Not Properly Shutdown
  4. Cabin Overheat Protection

Tesla vehicles perform a number of actions automatically in order to maintain smooth operation. If you hear your Tesla’s fan running for no appropriate reason, do not panic or call customer service, unless it is absolutely necessary. There are a number of completely normal reasons that your Tesla is running its ventilation systems. Don’t get alarmed until you know what is “normal.”

4 Reasons Your Tesla’s Fans Keep Running

New owners and old owners alike, those who are lucky enough to drive a Tesla, have likely noticed that at some point in time, your car will activate its fans (plural), seemingly without any good reason. 

Some have reported hearing their car’s fans running for extended periods of time, even while parked, or after a short drive. The truth is, your car is functioning normally. Here is a list of probable reasons your Tesla fans are running.

1. Automated Climate Control is Activated

One of the many convenient features of Tesla vehicles is the ability to activate an automated climate control system, which will keep the cabin of the car at a chosen temperature for as long as the car is running. 

The climate control feature is on by default but can be easily deactivated through the Tesla app. Automated climate control will remain active for a period of time even after the car has been turned off.

2. Battery Heat Level Maintenance

As an electric car company, all Tesla vehicles are made to run off of batteries instead of internal combustion engines. While you might think that batteries would never get hot enough to need cooling, the reality is to the contrary. The batteries that Tesla cars run off of need to be kept within a certain temperature range in order to maintain stability and safety.

If you hear your Tesla’s battery fans running intermittently over long periods of time, even when it is not charging, it is likely your car is simply trying to keep the batteries from overheating due to warm surroundings, or it is performing a standard cooling process after having been driven.

3. Tesla Not Properly Shutdown 

One of the most common reasons your Tesla’s fans are running is because the car has not been fully powered off. One of the easiest ways to inadvertently prevent your Tesla from fully powering down is to leave the door ajar or still be close enough to the vehicle that your phone is still connected via bluetooth.

It is an easy mistake to make, but if it happens, some of the interior lights and automated processes that should otherwise be off will remain turned on, the automated climate control feature being one of them.

Another easy mistake to make is forgetting to disconnect Bluetooth devices, such as your phone, from the car. If a Bluetooth device remains connected and within range to the car, some automated features will continue to run. You’ll be able to tell you are still connected by the side mirrors on the vehicle, if they are still open, you are still connected. Make sure you walk far enough away that your side mirrors fold in and the car locks.

4. Cabin Overheat Protection

Another cool and practical feature of Tesla cars is their automatic cabin overheat protection, an automated feature that prevents the cabin of the car from reaching above 104 degrees Fahrenheit. This feature is on by default to ensure that the car will always be tolerable to drive, no matter where you are parked or how hot the weather conditions become.

How to Turn Off a Tesla Fan

Despite being known for their extremely quiet engines, even while driving, electric cars, and particularly Teslas, actually make a fair bit of noise, even when they are not turned on. While the primary source of noise from a Tesla will come from its many fans, the actual amount of sound they make is not very much but is still enough to annoy some people.

If you are one of those individuals who finds the constant fan noises from your Tesla to be annoying, or if you want as little phantom battery drain as possible, then you will be happy to know that there are ways to mitigate frequency with which your Tesla uses its various fans.

While there are some automated fan systems that cannot be turned off, you can stop most of the cars fans by using any of the three methods described in the list below.

How to Turn Off Tesla Fans

  1. Turn Off The HVAC: You can turn off the heating and air conditioning for your Tesla by pressing and holding the fan icon for a few seconds. Doing so will turn off the AC and the blower.
  2. Turn Off Climate Control: Either through your Tesla’s dash or through the app, you can navigate to the climate control menu to turn off any automated features.
  3. Open and Close a Door: If you notice a fan is running on your Tesla but everything seems like it is turned off, you can open and close any of the car’s doors to stop random fan noises. You may also need to walk away far enough that your phone’s bluetooth disconnects so the car locks and he side mirrors fold in.

What Features Do Teslas Have?

Tesla vehicles are packed full of some of the latest and most technologically innovative features that have ever been put in a car. 

But, for the most part, all that people know about Tesla is that they make electric cars with computers in them. If you are thinking of buying a Tesla, you probably want to know exactly what the car offers.

For the most part, all Teslas that can be currently purchased will contain the same basic set of features, but there are some specific abilities that are limited to specific models of car. A few of the most interesting and useful features are listed below.

Features That Come With Your Tesla

  1. Folding Mirrors: Both the Tesla Model S and Model 3 have automatic folding mirrors which can be activated when parked in a tight location. The Model 3 takes it a step further with a planned update for geolocation implementation, which will activate the mirrors automatically when driving in certain areas.
  2. Dog Mode: With Tesla’s new “Dog Mode,” you never have to worry about leaving your fluffy companions in the car on a hot day. When activated, “Dog Mode” keeps the internal temperature of the car at a comfortable level until you return.
  3. AutoPilot: The Autopilot feature on Tesla cars allow the vehicle to automatically maintain speed with surrounding traffic as well as auto steer itself when in a clearly marked lane. Even cooler is the fully driverless functionality which will soon be coming to the Model 3.
  4. Ludicrous Plus Mode: Ludicrous Plus Mode is a secret mode that can be unlocked by going to the settings menu and holding down “Ludicrous Mode” for five seconds. Once unlocked, you will be able to go from 0 to 60 mph in under 2.4 seconds.
  5. Streaming Services: All Tesla cars come with a smart device interface, but they can be used for more than just GPS and radio. In fact, when the car is parked, you can browse the web, stream video, or listen to Spotify, and all on a comfortably large screen.
