What This Guide Helps With
Chair not powering on, intermittent operation, or loss of functions due to power source, cord, or connection-related issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the chair from active patient use before troubleshooting.
- Expected: Patient safely relocated to another chair.
- Why it matters: Power instability can cause unexpected movement or loss of positioning.
Verify the Reported Issue
- Attempt to power on the chair and operate all functions (hi-lo, tilt, back).
- Expected: Confirm no power, intermittent power, or partial function loss.
- Why it matters: Helps determine if the issue is total power failure or localized.
Check Power Source (Outlet)
- Confirm the chair is plugged into a known working outlet. Test the outlet with another device.
- Expected: Outlet provides consistent power.
- Why it matters: Loss of facility power is the most common and easily corrected issue.
- If no power → restore power and retest
Inspect Power Cord and Plug
- Check the entire length of the power cord for cuts, fraying, or damage. Inspect the plug for bent prongs.
- Expected: Cord intact with no visible damage.
- Why it matters: Damaged cords can cause intermittent or no power.
- If damaged → remove from service and replace cord
Check Power Entry Point on Chair
- Inspect where the power cord enters the base of the chair. Ensure it is secure and not loose or strained.
- Expected: Firm, stable connection with no movement.
- Why it matters: Loose internal connections at the entry point are a common failure point.
Look for Indicator Lights or Sounds
- Check for any control panel lights, relay clicks, or signs of power when plugged in.
- Expected: Lights or audible signs of power presence.
- Why it matters: Helps determine if power is reaching the chair but not distributing properly.
Test Hand/Foot Controls
- Attempt to operate the chair using all available controls.
- Expected: No response or intermittent response across all functions.
- Why it matters: Confirms whether the issue is upstream (power) vs. control-specific.
- If controls partially work → issue may not be total power failure
Check for Tripped Breakers or Power Strips
- If the chair is connected through a power strip or shared circuit, verify it has not tripped.
- Expected: Continuous, uninterrupted power supply.
- Why it matters: External protection devices can interrupt power without obvious signs.
Inspect for Signs of Internal Electrical Issues (External Observation Only)
- Look for burning smell, discoloration, or heat near the base.
- Expected: No abnormal smell, heat, or visible damage.
- Why it matters: Indicates possible internal wiring or component failure.
- If present → immediately remove from service
If the Problem Persists
If all external power sources, cords, and connections have been verified, the issue is likely internal (power supply, wiring harness, or internal distribution components).
Remove the chair from service, label it Out of Service, and send for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and is part of proper troubleshooting.
Clinical Use Tip
Never troubleshoot a powered chair while a patient is seated. Always transfer the patient before testing power or movement functions.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Procedure chair would not power on and was non-responsive to controls."
Cause
What was observed during troubleshooting.
Example:
"Fault traced to damaged power cord at strain relief causing intermittent power loss."
Resolution
What action was taken.
Example:
"Replaced power cord and verified full chair functionality."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power cord condition
- Indicator lights present or absent
- Control response behavior
- Any unusual sounds, heat, or smell
- Final operational status
Final Thought
Start with simple power checks and external connections before assuming internal failure. Patient safety comes first, and proper escalation prevents unnecessary risk. Clear documentation supports future reliability and service efficiency.
That is successful troubleshooting.
