Understanding the 'Reset'
A 'reset' on a power chair is a troubleshooting step used to clear temporary electrical faults or software glitches in the control system. It is similar to restarting a computer. Most reset procedures fall into a few key categories, ranging from a simple power cycle to a manual circuit breaker reset, each addressing different potential issues.
Method 1: The Soft Reset (Power Cycle)
This is the most basic and often most effective reset method for a power chair. It’s the first thing you should always try when you encounter a problem, such as unexplained stalling, unresponsive controls, or a flashing error light.
Step-by-Step Soft Reset:
- Turn Off the Power: Find the main power button or key switch on your joystick or control panel and turn the power chair completely off.
- Wait: Give the chair about 30-60 seconds for the electrical systems to completely discharge and for any controller memory to clear. This is an important step that many people skip.
- Turn On the Power: Turn the power chair back on. Listen for the start-up beep or check for the power lights to indicate that the system has successfully rebooted.
- Test the Controls: Slowly and carefully test the joystick and other functions to see if the issue is resolved.
Method 2: The Hard Reset (Circuit Breaker)
If a soft reset doesn’t work, the next step is a hard reset by checking the main circuit breaker. This is often necessary if the chair's motor or electrical system has been overloaded, causing the safety circuit to trip. A tripped breaker will completely cut power to the chair.
Locating and Resetting the Breaker:
- Location: The circuit breaker is a small, usually round or rectangular, button found in a few key locations. Check near the battery housing, under the seat, or on the main power module.
- Appearance: The button is often rubberized and may be white, red, or black. Some have a clear plastic cover.
- Action: If the circuit breaker has tripped, the button will be popped out. Simply press it in firmly until you hear or feel a click. If the button stays in, the breaker is reset. If it immediately pops out again, there is a persistent electrical fault and you should call a technician.
Method 3: Joystick-Specific Resets
Some power chairs, particularly models with more advanced joystick controls, have built-in reset or 'inhibit mode' protocols. These are often triggered accidentally and require a specific button sequence to be cleared.
Common Joystick Reset Sequence:
- On/Off Sequence: For some models, the lock mode can be engaged by rapidly pressing the power button twice or holding it down. To unlock, the same sequence or a similar one may be needed. Consult your user manual for the exact steps.
- Joystick Command Sequence: Certain manufacturers, such as Jazzy or Quantum, use a series of joystick movements (e.g., forward-beep, reverse-beep, release-long beep) to unlock the system. This method is used to prevent accidental movement when the chair is unattended.
Before You Reset: The Essential Checks
Sometimes, what appears to be a need for a reset is actually a different issue entirely. Perform these simple checks first.
Pre-Reset Troubleshooting Checklist:
- Battery Charge: Is the battery fully charged? A low battery can cause erratic behavior that might seem like a system error. Plug the chair in for a full charge and try again.
- Connection Check: Are the battery terminals clean and tightly connected? Loose or corroded battery terminals can interrupt power flow. Check all harness connections for looseness, including at the joystick and motors.
- Freewheel Mode: Is the chair accidentally in freewheel mode? The levers on the back of the chair, near the motors, should be in the "drive" position, not the "freewheel" position. Driving in this mode is not possible.
- Charger Plug: Is the off-board charger still plugged into the chair? Most chairs will not operate while the charger is connected, regardless of whether the charger is plugged into a wall outlet.
Comparing Reset Methods
| Feature | Soft Reset (Power Cycle) | Hard Reset (Circuit Breaker) | Joystick-Specific Reset |
|---|---|---|---|
| Problem Type | Temporary glitches, unresponsive controls, system errors. | Electrical overloads, sudden power cuts, system failure to power on. | Inadvertent lock-out of joystick, special features, or transport mode. |
| Process | Turn off, wait 30-60s, turn on. | Locate and press the circuit breaker button. | Perform a specific sequence of button presses or joystick movements. |
| When to Use | Always the first step for any issue. | When the chair has no power and a soft reset fails. | When the joystick is locked and other resets fail. |
| Risk of Damage | None. Completely safe. | Minimal, but indicates an underlying electrical fault if it trips repeatedly. | None, but relies on knowing the specific sequence for your model. |
When to Call a Professional
While a reset is a great starting point for troubleshooting, it won't fix every problem. You should contact a qualified technician if:
- The chair fails to respond after attempting all reset methods.
- The circuit breaker repeatedly trips immediately after being reset.
- You notice any flashing light error codes on the controller that you cannot diagnose.
- There are visible signs of damage to wires, connectors, or the controller.
- The chair operates inconsistently, such as lurching or stopping suddenly.
For more advanced troubleshooting and guidance, consult your specific model's user manual or visit the manufacturer's website. For example, Invacare provides a variety of support documents for their range of power chairs.
Conclusion: Regain Your Mobility Confidently
Knowing how do I reset a power chair? is an empowering piece of knowledge that can solve many everyday mobility issues, saving you time and the inconvenience of a service call. By starting with the simplest soft reset, moving to the circuit breaker, and considering joystick-specific protocols, you can resolve most common problems. Performing routine maintenance, like checking battery connections, further prevents future issues. Remember, your safety is the top priority. Always consult a professional for complex or persistent problems to ensure your power chair remains a reliable tool for your independence.
