The 5 red flashes is power-sharing communication issue. The last 3 issues above are the most common specific problems.

Here’s a quick overview of what’s happening when you see this pattern:

  • 1st, 2nd, and 3rd red blinks: Communication issue between the charger and your Tesla detected
  • 4th red blink: Ground fault. This is when electrical current leaks from its intended path, often due to moisture.
  • 5th red blink: Signals high temperature or poor power supply

So while 5 blinks together indicate a wider “system fault”, the last 1 or 2 flashes reveal the likely culprit.

Next let’s explore the causes and fixes for temperature issues, ground faults, and power supply problems with your Tesla charger.

High-Temperature Detection and Overheating

The 5th blink in the sequence calls attention to high-temperature detection. This can occur in either the wall connector itself, the wall outlet/wiring, or the adapter on the mobile connector.

Signs of Overheating

How do you know if part of your charging system is overheating? Here are some clues:

  • The wall connector or outlet feels hot to the touch
  • The adapter or connector has melted areas
  • Burning smell from wall outlet area
  • Reduced charging speed

Excess heat anywhere along the electricity flow to your battery indicates potential danger. Let’s explore why it happens and your solutions.

What Causes Overheating During Charging?

These factors can trigger high temp detection and overheating issues:

  • Tight space/inadequate ventilation: Heat can build up if the wall charger or outlet area lacks airflow
  • High charging current: Using maximum current for extended periods can cause overheating
  • Loose connections: Faulty wiring leads to resistance and excess heat
  • Outlet/wiring issues: Outdated, damaged, or incorrectly-sized wiring
  • Too many appliances/circuits on shared line: Overloads the electrical circuit

The key is pinpointing where the heat is building up. Then you can target the appropriate fix.

How to Fix Overheating Tesla Charger

Here are tips to troubleshoot and prevent overheating problems while charging your Tesla:

  • Improve ventilation: Ensure at least 12 inches of clearance in all directions around the wall charger
  • Reduce charging amperage: Lowering amps/current may cause it to overheat until wiring is addressed
  • Check connections: Inspect mobile connector adapter, wall outlet, and wiring for loose fittings
  • Replace defective parts: Faulty outlet, worn adapter, or damaged wiring can cause excess heat
  • Upgrade electrical panel: If the circuit shares too many devices, additional circuits may be needed
  • Call electrician: For persistent issues, professional inspection of wiring condition and capacity is advised

Taking the right steps to dissipate heat and address the root overheating cause will get your Tesla charging safely again.

Ground Fault Detection

A ground fault interruption (GFI or GFCI) can also trigger the 5 blinks on your Tesla connector. Let’s break down what causes ground faults and how to fix them.

What Triggers Ground Faults During Charging?

Here are typical ground fault triggers with Tesla home charging:

  • Moisture: Wet weather or irrigated landscaping can allow electricity to leak into the ground
  • Damaged charging equipment: Exposed wiring inside a cracked connector or charger cuts off power as a safety precaution
  • Poor outlet grounding: Inadequate grounding allows current to flow outside of the intended path
  • Shared circuit issues: Too many appliances on one circuit can cause flow deviations

Ground faults require quick troubleshooting since they indicate conditions that could be hazardous if charging continues.

Fixing Ground Fault Problems

When moisture, equipment faults, or wiring issues trigger the ground fault detection, here are smart steps:

  • Carefully inspect the charger, connector, and outlet for cracks/damage allowing moisture or bare wiring exposure
  • Ensure grounding wire connections are secure in both the wall outlet and circuit breaker box
  • Try charging from another GFCI outlet, like in the bathroom or kitchen, to isolate the issue
  • Use an extension cord to try different circuits instead
  • If problems persist in multiple outlets, an electrician should inspect the home wiring grounding and breaker box
  • Repair or replace any damaged charging equipment or outlets before continuing charging

With the right troubleshooting approach and safety checks, you can clear the ground fault and charge once again.

Poor Power Supply Quality

Finally, the 5 red blink pattern can also indicate distortion in the power supplied to your Tesla charger.

What Causes Poor Power Quality?

These types of electrical interference disrupt steady clean power flow:

  • Grid fluctuations: Issues at the utility transformer or distribution lines
  • Bad breaker: Faulty circuit breaker misbehaving
  • Shared circuits: Motor loads from appliances like fridges on the same circuit
  • Bad wiring: Outdated household wiring interfering with steady current
  • Weather events: Storms, lightning strikes, etc. disrupting the grid’s power quality

The charging systems in Tesla models are sensitive to these disturbances. That’s why your connector lets you know when it detects power quality issues.

Smoothing Power Supply to Fix Charging Problems

Here are tips to troubleshoot and prevent power quality problems when charging:

  • Try a different circuit: Plug into another outlet on a separate breaker/wiring to isolate the real issue
  • Check breaker: Ensure the circuit breaker, and other home electrical components like lugs and bus bars, are in good shape
  • Call an electrician: They can measure the power supply with professional tools to catch and address fluctuations
  • Add power conditioner: Installing device to smooth electricity flowing to the charger
  • Wait out grid issues: If storms or accidents cause temporary power supply problems, charging may resume when the grid recovers

Depending on the root cause, you can take steps to stabilize your home’s electrical supply and restore power to your Tesla charger.

Next Steps When Tesla Charger Keeps Blinking Red

Hopefully, the troubleshooting tips above get your Tesla charging safely once again. But if the red flashing persists despite your best DIY efforts, don’t keep forcing it. Safety first!

Here’s what to do next for ongoing blinking red light problems:

  • Stop trying to change until the issue is resolved

Still have some questions about troubleshooting 5 red light blinks on your Tesla charger? These common FAQs have additional answers.

Why does my Tesla charger keep flashing red 5 times?

The most common issues causing repeated 5 blink fault codes are:

  • Persistent overheating: Insufficient cooling and ventilation, overloaded electrical circuit, excessive charging current
  • Recurring ground faults: Moisture intrusion from sprinklers/rain allowing electricity to leak, continued use of damaged/malfunctioning charging equipment
  • Poor grid power quality: Shared circuit interference from appliances with electric motors, local transformer/distribution line fluctuations

Without fixing the core problem, the 5-blink alert returns when trying to charge once again.

The charger is protecting itself, your vehicle, and your home by cutting off electricity flow instead of trying to force a charge.

The high temperature, ground fault, or power quality issue detected is unsafe for continued high-voltage charging. So cutting off power avoids:

  • Fire risk from overheating charger/wiring/outlet
  • Risk of electrocution from current leaking into the ground
  • Risk of electrical damage to car or charger from dirty/irregular power

This failsafe function prevents safety hazards and more severe electrical issues down the road.

Yes, absolutely! The 5 red blinks just indicate an issue with the charging equipment or electrical supply—not your Tesla battery or drivetrain.

You can safely continue driving your Tesla same as always. Just don’t try charging from the malfunctioning equipment until the root cause is addressed. Plan to charge from alternative public charging stations in the interim if needed.

Do I need a new Tesla charger if it keeps blinking red 5 times?

Not necessarily. In many cases, the underlying issue is with household wiring, grounding, shared electrical circuits, moisture intrusion, etc. Upgrading or repairing parts of your home’s electrical system often resolves charger errors.

However, if troubleshooting reveals the wall connector, mobile charge cord, or the adapter itself has internal damage causing the recurring faults, replacement may indeed be required.


Dealing with a blinking red Tesla charger is annoying but solvable. Now that you know the common issues signaled specifically by 5 red flashes, you can methodically troubleshoot and restore smooth charging once again.

The key is to:

  • Thoroughly inspect connections, cables, outlets, and charging equipment for damage allowing ground faults
  • Provide proper ventilation and cooling around the charger
  • Consider electrical upgrades to supply clean steady current
  • Leverage professional support from an electrician when needed

Don’t forget to look up TSBs for your Tesla model year in case a known charger firmware issue with an update fix applies too.

With the right safety checks and targeted troubleshooting approach, a temperamental Tesla charger blinking red 5 times will be back to giving you a steady green light and a full battery in no time!
