To reset a Tesla Wall Connector, turn off the circuit breaker that feeds it, wait 5 seconds, and turn it back on. On the current Gen 3 unit, that is the whole procedure: it has no reset button, and Tesla does not publish a factory reset. Only the older Gen 2 has a button marked RESET.
Which method applies depends on the hardware, and most people looking up how to reset Tesla wall charger hardware have a Gen 3. If you are not sure what is on your wall, our guide to Wall Connector generations shows how to tell them apart in a few seconds: glass front and one light bar means Gen 3.
The Gen 3 has no reset button
Plenty of pages tell you to unscrew the Gen 3's cover and press a reset button on the circuit board. Tesla's installation manual describes no such button. Its documented reset for a Gen 3 fault is a power cycle at the breaker, and the replacement guide Tesla publishes for this unit only ever removes the four screws holding it to the wirebox, never an inner cover. Don't open the unit looking for a button; there is live 240 V wiring in the wirebox behind it.
There is also no Tesla-published factory reset for the Gen 3, as of October 2026. If you have seen a "hold the button for 30 seconds" method, it is not in any Tesla document we could find. Two things get mistaken for one:
- Holding the charge handle button for 5 seconds. This re-opens the Wall Connector's own setup Wi-Fi network so you or an installer can join it and change settings. Tesla describes it as part of commissioning, not as a reset. The unit's settings stay in place until someone changes them.
- Re-running commissioning. Commissioning is where the breaker size, Wi-Fi network and access control are set. Running it again lets you change those settings. Our guide to commissioning the Wall Connector covers the Tesla One app and the older browser method.
If what you really need is a clean slate because of a lost setup password or a unit stuck on a fault, Tesla's answer is the Diagnose flow on its Wall Connector troubleshooting page. Sign in, pick your generation, answer the questions, and choose "Lost Wall Connector Password" if that is the problem. Tesla says remote fixes can take up to 24 hours.
How to reset a Gen 3 Wall Connector at the breaker
- Write down the light pattern first. A red code disappears when power goes off. Count the blinks so you can look it up later on our blinking red fault codes page.
- Hang the handle up. Take it out of the car so the restart is clean.
- Find the right breaker. It is a two-pole breaker (one wide handle covering two slots), sized 60 A for full 48 A charging, in your main panel or a subpanel. It may be labeled "EV", "car charger" or "garage". Some installs also have a separate disconnect switch near the charger. Flip the handle only; never remove the panel cover.
- Switch it off and wait 5 seconds. The light bar should go dark.
- Switch it back on. All seven faceplate lights come on for up to 5 seconds. Then green lights show the configured breaker size for about 10 seconds.
- Plug in and watch. Solid green while idle and an animated green bar while charging means the fault cleared.
What the restart should look like
The startup display doubles as a settings check. The number of green lights shown after startup reflects the breaker size set at commissioning. If you expected full power on a 60 A circuit and the display looks lower, compare it with your installer's paperwork. Our page on the correct amp setting for your breaker lists each breaker size and the output it allows. Press and hold the handle button any time to show the setting again.
Clearing a fault without touching the breaker
A Gen 3 ground-fault lockout (one red blink) can be cleared from the handle. Press the button on the charge handle, or pull the handle out of the car and plug it back in. Tesla documents this specifically for the ground-fault lockout. Inspect the handle and cable for water or damage before you do it, because if the cause is still there the unit will trip again.
Gen 2 Wall Connector reset button
The Gen 2 is the one with a real button, labeled RESET. Tesla's Gen 2 manual names it but does not describe its position in words, so look on the unit's housing for the label. If you cannot find it without removing a cover, use the breaker instead; it does the same job with the case closed.
The button has two functions depending on how long you hold it:
| Hold time | What it does | How you know it worked |
|---|---|---|
| 2 to 3 seconds | Clears the fault without rebooting | Top light changes from red to green |
| 5 seconds | Forces a full reboot without cutting input power | Release when the top light turns green |
Tesla also recommends a breaker off and on cycle for a red error on the Gen 2. If the light goes back to flashing red after any of these, the cause has not been fixed.
Remember that a Gen 2 retries some faults by itself (every minute for voltage and over-current faults, every 15 minutes for a ground fault, up to four times), so a code that cleared overnight may only have retried successfully. A fault that keeps cycling deserves a visit from an electrician.
Resetting a Tesla Mobile Connector
The Mobile Connector cable has no reset button. Tesla's reset for the Gen 2 Mobile Connector is to unplug it from the car and from the outlet, then plug it back in. At startup all the green lights come on for a second; steady green afterward means it is standing by.
Owners searching for a Tesla mobile charger reset button usually have a red code that keeps returning. Several of that unit's codes are heat warnings at a plug connection, and owners on Tesla forums often trace them to a loose adapter or a worn outlet, so check that the adapter is pushed fully into the control box and that the wall outlet is not warm. The current Gen 3 Mobile Connector, with a vertical light like a small Wall Connector, has no button either; unplugging both ends is the sensible restart, though the Tesla reset page we checked covers only the Gen 2 and we have not found a published code list for the Gen 3.
When a reset helps and when it is the wrong fix
A reset clears a code. It does not repair what caused it. Use this table, based on the Gen 3 codes in Tesla's installation manual, before you cycle the breaker for the third time.
| Gen 3 light | Reset worth trying? | Real fix if it returns |
|---|---|---|
| Solid red | Yes, once | Contact Tesla with part and serial numbers |
| 1 red blink | Clear from the handle after inspecting | Electrician checks wiring for leakage |
| 2 red blinks | Rarely helps | Electrician checks the ground and panel bond |
| 3 red blinks | After it cools | Electrician checks wire size and terminal torque |
| 4 red blinks | Restart the router instead | Rejoin Wi-Fi |
| 5 red blinks | Yes | Re-link power-sharing units |
| 6 red blinks | After grid power settles | Electrician or utility measures voltage |
| 7 red blinks | Lower the car's amps first | Contact Tesla with VIN and time |
| No lights | Check the breaker has not tripped | If it trips again, call an electrician |
A breaker that trips by itself is a different situation from a deliberate reset. Turn it back on once. If it trips again, leave it off until an electrician has looked at the circuit.
Moving house, selling, or a "Product Already Registered" error
The usual reason people want a factory reset is to hand a Wall Connector to someone else. You don't need one. The new owner can register the unit in their Tesla app, and if the app says "Product Already Registered", Tesla's route is the "Initiate Transfer" option described on its Wall Connector app support page, with proof of purchase; Tesla says it responds within three business days.
If you are taking the unit with you, it must be re-commissioned at the new address because the maximum current is tied to the breaker it is installed on. Our guide on how to move a Wall Connector to a new house covers the removal side, which is a job for a licensed electrician.
Firmware: not something you can reset or force
Old advice about downloading a firmware file and loading it by hand does not apply to the Gen 3. Updates install automatically over Wi-Fi, usually overnight, and owners cannot trigger them. That is one more reason to keep the unit online. You can see the current firmware version in the Tesla app under Home, Settings, My Home Info, My Products.
Reset questions from Wall Connector owners
Where is the reset button on a Gen 3 Tesla Wall Connector?
There isn't one. The Gen 3, with its glass front and single vertical light bar, has no reset button inside or out, and Tesla's manual gives the breaker as its reset. Guides that tell you to remove the cover and press a button on the circuit board are describing something Tesla does not document.
Is there a factory reset for the Gen 3 Wall Connector?
Tesla does not publish one for owners as of October 2026. Holding the charge handle button for 5 seconds re-opens the setup Wi-Fi network so settings can be changed, but it does not wipe the unit. For a lost setup password, registration trouble or a unit that will not recover, use the Diagnose flow on Tesla's Wall Connector troubleshooting page.
Will cycling the breaker erase my Wi-Fi or amp settings?
Tesla does not describe the breaker reset as erasing anything, and it is the same thing the unit goes through after every power outage. When it powers back up, the green lights show the configured breaker size for 10 seconds, which is a quick way to confirm your amp setting survived. If it shows four red blinks afterward, it has not rejoined your Wi-Fi yet.
Can I reset the Wall Connector from the Tesla app?
The Tesla app shows status, schedules and charging history, but Tesla does not list a remote restart for the Wall Connector. A restart means cycling the breaker. Tesla's online Diagnose flow can push some fixes remotely, and Tesla says those can take up to 24 hours to arrive, so give it a day before running Diagnose again.
How do I reset a Tesla Mobile Connector?
Unplug it from the car, unplug it from the wall outlet, wait a few seconds, then plug it into the wall first and the car second. That is Tesla's reset for the Gen 2 Mobile Connector. If the same red code returns, check the plug adapter is pushed fully home and that the outlet is not warm, since several of its codes are heat warnings at the plug.
How many times should I try a reset before calling for help?
Once or twice. If the same code returns after a clean breaker cycle, the fault is real and repeating the reset only delays the fix. Ground, temperature and voltage codes need an electrician to test the circuit. A solid red light that keeps coming back is a Tesla support case; have the part and serial numbers ready.
