When your Stiltz homelift stops working, it can feel stressful – especially if you depend on it daily to move safely between floors. The good news is that most Stiltz homelift problems have straightforward fixes you can handle on your own. The single most common cause of a Stiltz homelift not responding is an obstruction of the light curtain at the cab entrance, which is resolved simply by clearing the area and standing closer to the rear wall of the lift.
Structured Troubleshooting Guide | Mobility123
At Mobility123, we are the only preferred Stiltz ProPartner in New Jersey, and our licensed elevator mechanics have serviced thousands of Stiltz homelifts across the tri-state area. This guide covers the 11 most common Stiltz homelift issues we see, with step-by-step solutions to get your lift running again quickly.
Before You Start: Safety First
Before troubleshooting any issue with your Stiltz homelift, keep these safety basics in mind:
- Never attempt to force the lift door open or manually move the cab.
- If you smell burning or see smoke, turn off the main power immediately and call Mobility123.
- Keep children and pets away from the lift while troubleshooting.
- If the lift is stuck between floors with someone inside, use the emergency battery lowering feature (the lift will descend automatically during a power outage) or call for professional help.
Common Stiltz Homelift Problems and How to Fix Them
1. Stiltz Homelift Will Not Move or Respond
This is the most frequently reported issue, and it has several possible causes. Work through these checks in order:
Light curtain obstruction (most common): The light curtain guards the cab entrance and will prevent the lift from moving if anything breaks the beam. A handbag, arm, or even a coat sleeve can trigger it. Look for the LC (light curtain) indicator light flashing on the cab operating panel. Clear the entrance area completely and stand closer to the rear wall of the cab.
Key switch turned off: Check the Cab Operating Panel (C.O.P.) key switch. The lift will only operate when the key is in the horizontal (on) position. Turn the key to horizontal and try again.
Emergency stop button engaged: If someone pressed the red emergency stop button, the lift will not move until you reset it. Turn the button clockwise until it pops out. Then turn the key switch off and back on to complete the reset cycle.
Door latch not making full contact: Shift your position inside the cab and try operating the lift again. Gently lift or push the cab door to ensure it is fully seated in the latch. If this does not resolve the issue, contact Mobility123 to schedule a service visit.
Main power is off: Check the red indicator lamp on the ceiling toward the rear of the cab. If it is off, your home's power supply to the lift has been interrupted. The emergency battery system will activate and allow the lift to descend, but it will not travel upward without main power. Wait for power to be restored.
Manual lifting attempt: If anyone has tried to manually push or lift the cab, the internal lifting mechanism may need to be reset by a professional. Call Mobility123 for service.
Lift passed its landing stopping points: If the cab has traveled past its lower or upper stopping point, the door will open to allow safe exit. This requires a service visit from Mobility123 to recalibrate the landing positions.
2. Both Light Curtain (LC) and Overload (OL) Lights Flickering
When the LC and OL indicator lights flicker simultaneously, this typically signals an over-speed sensor issue. The over-speed sensor is a safety mechanism that stops the lift if it detects the cab moving faster than its designed speed. This is not a user-serviceable issue. Call Mobility123 to arrange a service visit.
3. Battery Backup System Activated (LC and OS Lights Flickering)
If you see the LC and OS lights flickering, the lift may have switched to its battery backup power. Check the ceiling-mounted switch in the cab – it should be glowing red, indicating that main power is connected. If the light is off or the OS indicator is active, verify that the home's circuit breaker supplying the lift has not tripped. If the main power connection is confirmed and the issue persists, contact Mobility123 for a service visit.
4. Stiltz Homelift Remote Controls Not Working
Stiltz homelifts come with landing remote controls for calling the lift to each floor. If the remotes stop responding:
Replace the batteries: Each remote uses three AAA batteries. Replace the batteries in all remote controls, not just the one that appears unresponsive.
Move within range: The remote controls have an optimal working range of about 10 feet from the lift. Move closer and try again. Walls and electronic interference can reduce the effective range.
5. Lift Only Moves Up, Not Down
If the lift travels upward but refuses to descend, there is likely a physical obstruction beneath the cab. Before using the lift, visually inspect the area directly below the cab from the lower floor. Remove any objects, furniture, boxes, or debris that could be blocking the path. The lift's safety sensors prevent downward travel when something is detected in the way.
6. Lift Only Moves Down, Not Up
Several issues can prevent upward travel:
Obstruction on the shaft lid or cab ceiling: Check the top of the lift cab and the shaft opening at the upper floor for any items that may have fallen or been placed on top. Remove any obstructions.
Main power off with emergency battery active: The battery backup system only supports downward travel. If the main power indicator light (red lamp in the cab ceiling) is off, the lift is running on emergency battery power. Wait for main power to be restored.
Safety cover catching on guides: From the upper floor, watch the lift as it attempts to travel upward. If the safety cover appears to tilt rather than rising level, it may be catching on the guide rails. This requires professional adjustment – call Mobility123.
7. Lift Cab Moves on Its Own
If the cab appears to move without anyone pressing a button, the most likely cause is unintentional activation from a landing remote control. This can happen if a remote is placed on a surface where it gets bumped, or if something presses against the buttons. Keep each landing remote control at its designated landing location and ensure the buttons are not being accidentally pressed by nearby objects.
8. Dim Ceiling Lights and Unresponsive Remote Controls
The ceiling downlights in your Stiltz homelift are powered by the lift's internal battery. If you notice the lights dimming and the remote controls stop working at the same time:
Check the cab position: Always park the lift fully at the top or bottom landing when not in use. Leaving the cab stopped mid-travel for extended periods can drain the battery.
Low battery: If parking the lift at a landing does not resolve the issue, the internal battery may need attention. Contact Mobility123 to schedule a service visit for battery inspection or replacement.
9. Stiltz Homelift Door Will Not Open
Lift not level with the landing: The door will only open when the cab is fully aligned with a floor landing. Use the C.O.P. buttons or the landing remote control to move the lift to the correct floor. Hold the directional button until the lift comes to a complete stop at the landing.
Door hitting the upper floor threshold: If the lift is at the upper landing and the door will not open, try driving the cab down slightly using the C.O.P. buttons. Hold the button until the cab stops. This can resolve a minor alignment issue where the door contacts the floor threshold.
10. Buzzer Sounding Continuously
Emergency stop button: A continuous buzzer often indicates the emergency stop button has been pressed. Turn the stop button clockwise until it pops out, then reset the lift by turning the key switch off and back on.
Battery backup system fault: If the buzzer continues after resetting the stop button, there may be a fault with the backup battery system. This requires a professional diagnosis. Call Mobility123 for service.
11. Humming Sound from the Electrical Panel
A persistent humming sound from the lift's electrical panel relays can indicate an excessive voltage supply. If you have access to a voltage meter, check the supply voltage. The Stiltz homelift uses a 110V step-up transformer, and the input may be incorrectly set to 230V instead of the required 115V. If you are not comfortable working with electrical components, contact a qualified electrician or call Mobility123 for assistance.
When to Call a Professional
Some Stiltz homelift issues require trained service technicians with specialized tools and knowledge. Contact Mobility123 for professional service if:
- The over-speed sensor has triggered (LC and OL lights flickering together)
- Someone has attempted to manually lift the cab
- The lift has passed its landing stopping points
- The safety cover is catching on the guide rails
- The backup battery system shows a persistent fault
- Any issue persists after you have completed the troubleshooting steps above
Regular preventive maintenance is the best way to avoid unexpected breakdowns.

Frequently Asked Questions
Why is my Stiltz homelift not working?
The most common reason a Stiltz homelift stops working is an obstruction of the light curtain at the cab entrance. Items like bags, clothing, or even an arm can break the beam and prevent the lift from operating. Clear the entrance, stand toward the rear wall, and try again. If the light curtain is not the issue, check that the key switch is in the on (horizontal) position and that the emergency stop button has not been pressed.
How do I reset my Stiltz homelift after an emergency stop?
To reset your Stiltz homelift after an emergency stop, turn the red stop button clockwise until it pops out. Then turn the C.O.P. key switch to the off position and back to the on (horizontal) position. This completes the reset cycle and the lift should be ready to operate again.
How often should a Stiltz homelift be serviced?
Stiltz recommends professional maintenance at least once per year. Mobility123 offers maintenance plans with one or two service visits annually, performed by licensed elevator mechanics. Regular servicing helps identify worn components, ensures safety systems are functioning properly, and extends the life of your homelift.
What does it mean when the lights are flickering on my Stiltz homelift?
Flickering indicator lights on your Stiltz homelift point to different issues depending on which lights are affected. If both the LC (light curtain) and OL (overload) lights flicker together, the over-speed sensor has triggered and you need professional service. If the LC and OS lights flicker, the battery backup system has activated, usually because main power has been interrupted. Check your home's circuit breaker and the red power indicator lamp in the cab ceiling.
