What This Guide Helps With
Troubleshooting control failure, missed button response, foot control problems, or programmable position issues on a Brewer AssistPRO 7500 procedure chair.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Do not troubleshoot chair movement while a patient is being examined, transferred, or positioned unless it is safe to do so.
Action:
- Move the patient to another chair or exam surface if the chair is stuck, moving unpredictably, or not responding correctly.
- Do not continue using the chair if motion controls are intermittent or unreliable.
Expected outcome: Patient care continues without relying on a chair with questionable movement control.
Why it matters: A procedure chair that does not respond correctly can create fall, pinch, positioning, or transfer risk.
If this resolves the immediate patient care issue, continue troubleshooting only after the chair is no longer in active use.
Verify the Reported Control Problem
Confirm whether the issue affects the hand control, foot control, programmable positions, or all chair movement.
Action:
- Ask staff what failed:
- Hand control does not respond
- Foot control does not respond
- Only one button or function fails
- Programmed positions do not work
- Home position does not work
- Chair moves manually but not by memory/program button
- Chair does not move at all
- Test each chair function one at a time.
Expected outcome: The failure pattern is identified.
Why it matters: A single failed control button is different from a power, lockout, connection, or actuator issue.
If only one control method fails but the other works normally, focus on that specific control and its cable/connection.
Check AC Power and Chair Power Status
Before blaming the control, confirm the chair has proper power.
Action:
- Verify the chair is plugged into a working outlet.
- Confirm the power cord is fully seated and not damaged.
- Check for any visible power indicator, display, or signs that the chair is powered.
- Test the outlet with another device or outlet tester if needed.
Expected outcome: The chair has confirmed AC power.
Why it matters: Controls cannot operate correctly if the chair has no power, low power, or an unstable outlet connection.
If power is restored and the controls work normally, return the chair to service after functional testing.
Inspect the Hand Control
Check the hand control for obvious external damage.
Action:
- Inspect the hand control body, buttons, cable, strain relief, and connector.
- Look for:
- Cracked housing
- Sticky or stuck buttons
- Fluid contamination
- Torn cable jacket
- Bent connector pins
- Loose plug
- Pinched cable under the chair base or frame
- Reseat the hand control connector if accessible externally.
Expected outcome: The hand control is clean, intact, and securely connected.
Why it matters: Procedure chair hand controls are frequently damaged by pulling, cleaning fluids, bed/chair movement, or cable strain.
If the hand control works after reseating the connector, perform full chair function testing before returning the chair to service.
Inspect the Foot Control
If the foot control is not responding, check for damage or obstruction.
Action:
- Inspect the foot control pedal, cable, connector, and surrounding area.
- Confirm the pedal is not physically jammed under the chair, against a wall, or caught under equipment.
- Check for fluid intrusion, cracked housing, loose cable, or damaged strain relief.
- Reseat the foot control connector if accessible externally.
Expected outcome: The foot control is physically intact, unobstructed, and securely connected.
Why it matters: Foot controls are exposed to floor impact, rolling equipment, cleaning solution, and cable damage.
If the foot control works after correcting the connection or obstruction, stop and document the correction.
Compare Hand Control and Foot Control Operation
Use one control method to help isolate the other.
Action:
- Test each movement function from the hand control.
- Then test the same functions from the foot control.
- Compare the results.
Expected outcome:
- If hand control works but foot control does not, suspect the foot control, foot control cable, or foot control connection.
- If foot control works but hand control does not, suspect the hand control, hand control cable, or hand control connection.
- If neither control works, suspect chair power, safety interlock, control board, actuator system, or internal wiring.
Why it matters: Comparing both control methods helps avoid replacing parts unnecessarily.
If one control works reliably, the chair movement system is likely capable of operating, and the failed input device becomes the stronger suspect.
Check for Stuck or Held Buttons
A stuck button may prevent normal operation or interfere with programmed movement.
Action:
- Press and release each button on the hand control and foot control.
- Feel for buttons that stick, bind, fail to click, or remain depressed.
- Inspect for cleaning residue or contamination around buttons.
Expected outcome: All buttons move freely and return to their normal position.
Why it matters: A stuck input can lock out other commands or cause the chair to ignore new commands.
If a stuck button is found, remove the chair from service until the control can be cleaned, replaced, or evaluated.
Verify Chair Movement Is Not Mechanically Blocked
The controls may be working, but the chair may be unable to complete movement due to obstruction.
Action:
- Check around the base, back section, leg section, and under-chair area.
- Remove any objects, cords, stools, trash cans, equipment, or wall contact points blocking movement.
- Confirm the chair is not overloaded or positioned against another object.
Expected outcome: The chair has a clear path for all movement.
Why it matters: A blocked chair may appear to have a control failure when the control system is actually preventing movement or stalling.
If removing the obstruction restores normal operation, perform full movement testing and return to service if safe.
Test Individual Chair Functions
Determine whether all functions fail or only certain movements fail.
Action:
- Test:
- Raise
- Lower
- Back recline
- Back upright
- Leg section movement, if equipped
- Home/return function
- Programmed position buttons, if equipped
- Use both hand and foot controls where applicable.
Expected outcome: The failed function is isolated.
Why it matters: One failed movement may point toward a specific actuator, switch input, or wiring path. A total failure points more toward power, control, or system-level issues.
If only one movement fails from both controls, remove the chair from service for bench evaluation or repair.
Check Programmable Position Behavior
If the chair moves manually but programmed positions fail, focus on the memory/program function.
Action:
- Confirm that manual movement buttons still operate normally.
- Try moving the chair to a simple known position and then using the programmed position or home button.
- Verify staff are using the correct program/home button sequence if applicable.
- Ask whether the issue began after a power interruption, cleaning, relocation, or control replacement.
Expected outcome: Manual movement and programmed movement behavior are clearly separated.
Why it matters: A memory/program problem may not mean the whole chair is failed. It may involve programming, control input, or position feedback.
If manual movement works but programmed positioning remains unreliable, remove the chair from service if the programmed function is required for clinical use.
Power Cycle the Chair
A control or position command issue may clear after a controlled reset.
Action:
- Lower the chair only if safe and possible.
- Disconnect the chair from AC power.
- Wait briefly.
- Reconnect power and retest the hand control, foot control, and programmed functions.
Expected outcome: Temporary logic or control lockup clears and normal function returns.
Why it matters: Power cycling can clear some control-related glitches without internal repair.
If the problem returns, do not keep cycling power as a workaround. Escalate the chair for evaluation.
Perform a Full Functional Check Before Return to Service
If the issue appears resolved, verify the chair is safe before returning it to clinical use.
Action:
- Run the chair through the full range of expected motion using the repaired or reseated control.
- Confirm:
- Smooth raise/lower movement
- Smooth recline/upright movement
- No unexpected motion
- No intermittent control response
- Foot control and hand control operate as intended
- Programmed/home positions function if used by the department
- No unusual noise, heat, smell, or cable strain
Expected outcome: The chair operates consistently and safely.
Why it matters: Intermittent control issues can return during patient positioning, which creates a safety concern.
If all functions pass, document the work and return the chair to service.
If the Problem Persists
If the hand control, foot control, or programmable position issue continues after power, connections, accessories, button condition, obstructions, and basic function checks have been ruled out, the issue is likely internal.
The chair should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
Possible internal causes may include a failed control pendant, failed foot control, damaged internal wiring, actuator issue, control board problem, or position feedback fault.
Knowing when to stop is proper troubleshooting. Do not continue using a procedure chair with unreliable movement controls.
Clinical Use Tip
Do not troubleshoot control or positioning problems while a patient is on the chair unless there is no safer option. Move the patient first, then troubleshoot. A chair that moves unpredictably or fails to respond should be treated as a patient safety risk. Move the patient to a backup chair or exam surface first so therapy continuity and patient care can continue safely.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Staff reported the Brewer AssistPRO 7500 procedure chair hand control and programmed position buttons were not responding consistently."
Cause
What was observed during troubleshooting.
Example:
"Found the hand control cable loose at the external connector, causing intermittent chair movement commands."
Resolution
What action was taken.
Example:
"Reseated the hand control connector, inspected the cable and buttons, verified hand control, foot control, raise/lower, recline, and home position operation, and returned the chair to service."
Helpful Details to Include (If Known)
- Outlet tested
- Chair power confirmed
- Hand control inspected
- Foot control inspected
- Control cables reseated
- Buttons checked for sticking
- Obstructions checked under and around chair
- Manual movement tested
- Programmable/home position tested
- Any intermittent behavior noted
- Unusual sounds, heat, smell, or fluid damage
- Final device status
Final Thought
Procedure chair troubleshooting should stay simple and safety-focused. Confirm the patient is safe, verify power, check control connections, compare hand and foot control behavior, and rule out obstructions before suspecting internal failure. If the chair still does not respond correctly, remove it from service and document the issue clearly using CCR.
That is successful troubleshooting.
