What This Guide Helps With
Table not powering on, intermittent power loss, or loss of function due to external power or connection-related issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the table from active patient use before troubleshooting.
- Expected: Patient safely relocated to another table.
- Why it matters: Power instability can lead to unexpected movement or loss of positioning.
Verify the Reported Issue
- Attempt to power on the table and operate all functions. Observe for no power, intermittent operation, or partial function.
- Expected: Confirm complete or intermittent loss of power.
- Why it matters: Determines if issue is total power failure or partial system issue.
Check Power Source (Outlet)
- Confirm the table is plugged into a known working outlet. Test the outlet with another device if needed.
- Expected: Outlet provides consistent power.
- Why it matters: Power loss at the source is the most common and easiest issue to correct.
- If no power → restore power and retest.
Inspect Power Cord and Plug
- Check the entire power cord for cuts, fraying, kinks, or damage. Ensure plug blades are intact and secure.
- Expected: Cord is intact with no visible damage.
- Why it matters: Damaged cords can cause intermittent or no power.
- If damage is found → remove from service and replace cord.
Check Power Cord Connection at Table
- Inspect where the power cord enters the table base. Ensure it is fully seated and not loose.
- Expected: Secure connection with no movement.
- Why it matters: Loose connections can mimic internal wiring faults.
- If loose → reseat and retest.
Inspect for Strain or Pinching
- Check if the power cord is pinched under the base, wheels, or caught in moving parts.
- Expected: Cord is free and not under stress.
- Why it matters: Pinched wiring can cause intermittent power loss.
- If pinched → reposition cord and retest.
Check Circuit Breaker or Power Switch (If Equipped)
- Locate any resettable breaker or main power switch on the table base. Reset if tripped.
- Expected: Breaker remains set and table powers on.
- Why it matters: Overcurrent conditions may trip protection and stop power.
- If breaker trips again → likely internal fault.
Inspect Hand Control and Control Cable
- Ensure the hand control is properly connected and cable is not damaged.
- Expected: Secure connection and intact cable.
- Why it matters: Some tables will appear non-functional if control signal is lost.
- If damaged or loose → correct and retest.
Observe for Signs of Internal Electrical Issues
- Look for burning smell, unusual heat, clicking, or intermittent power behavior.
- Expected: No abnormal signs present.
- Why it matters: These indicate likely internal wiring or power supply failure.
- If any signs are present → remove from service immediately.
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 control components).
Remove the table from service, label it Out of Service, and send for repair or bench evaluation.
Do not attempt internal electrical repair in the field.
Clinical Use Tip
Never troubleshoot a powered exam table with a patient on it. Always transfer the patient first to prevent injury from sudden loss or return of power.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Table would not power on and had no response to hand control."
Cause
What was observed during troubleshooting.
Example:
"No external power issues found; suspected internal power supply or wiring fault."
Resolution
What action was taken.
Example:
"Removed from service and sent to Clinical Engineering shop/vendor for repair."
Helpful Details to Include (If Known)
- Outlet tested and verified working
- Power cord condition (intact/damaged)
- Breaker status (tripped/reset)
- Hand control connection checked
- Any intermittent power behavior
- Any unusual smell, heat, or sound
- Final device status (removed from service)
Final Thought
Effective troubleshooting starts with simple external checks before assuming internal failure. Patient safety always comes first, and recognizing when to escalate prevents unnecessary risk. Clear documentation ensures continuity and accountability.
That is successful troubleshooting.
