What This Guide Helps With
Control inputs not activating chair movement due to power, connection, or accessory-related issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the chair from active patient use before troubleshooting.
- Expected: Patient safely relocated.
- Why it matters: Loss of control can result in unsafe positioning or sudden movement.
Verify the Reported Issue
- Attempt to operate the chair using both the hand control and foot control (if equipped).
- Expected: No response or intermittent movement.
- Why it matters: Determines if issue is isolated to one control or system-wide.
Check Power to the Chair
- Confirm the chair is plugged into a known working outlet. Test outlet if needed.
- Expected: Chair has consistent power (indicator lights if applicable).
- Why it matters: No power = no control response.
- If no power → restore power and retest.
Inspect Power Cord and Connection
- Check for loose plugs, damaged cords, or strain at entry points.
- Expected: Cord intact and securely connected.
- Why it matters: Intermittent power can mimic control failure.
Check Control Cable Connections
- Inspect where the hand control and/or foot control connect to the chair (typically under the seat or base). Ensure connectors are fully seated.
- Expected: Secure, tight connections with no looseness.
- Why it matters: Loose or partially connected cables are a common failure point.
- If loose → reconnect and retest.
Inspect Control Cables for Damage
- Run hands along cables checking for cuts, pinches, or exposed wires.
- Expected: No visible damage.
- Why it matters: Damaged cables interrupt signal transmission.
- If damaged → remove from service and replace control.
Test Each Control Independently
- If both hand and foot controls are present, test each separately.
- Expected: At least one control functions normally.
- Why it matters: Helps isolate whether the issue is with a specific control or the chair system.
- If one works → faulty control accessory
- If neither works → continue troubleshooting
Check for Obstructions or Mechanical Binding
- Ensure nothing is preventing chair movement (base obstruction, debris, etc.).
- Expected: Chair moves freely when activated.
- Why it matters: Mechanical resistance may appear as control failure.
Power Cycle the Chair
- Unplug the chair, wait 10–15 seconds, then reconnect power.
- Expected: Controls respond after reset.
- Why it matters: Resets control system and clears minor faults.
If the Problem Persists
If power, connections, controls, and external factors have been ruled out, the issue is likely internal (control board, actuator interface, or wiring harness).
Remove the chair from service, label 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 procedure chair while a patient is seated. Always transfer the patient to a safe alternative before testing controls.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Chair not responding to hand or foot control during patient positioning."
Cause
What was observed during troubleshooting.
Example:
"Loose hand control cable connection under chair base."
Resolution
What action was taken.
Example:
"Reconnected cable and verified full chair functionality."
Helpful Details to Include (If Known)
- Outlet tested and confirmed working
- Power cord condition
- Control type affected (hand, foot, or both)
- Cable condition and connection status
- Any indicator lights present or absent
- Any unusual sounds or lack of motor activity
- Final device status (functional or removed from service)
Final Thought
Start with simple, external checks—power, connections, and accessories resolve most issues quickly. When both controls fail and no external cause is found, escalate appropriately. Safe troubleshooting and clear documentation support both patient care and efficient repairs.
That is successful troubleshooting.
