Can I Replace the Chair Motor in My Lift Chair Myself?

Lift chairs, also known as power recliners, provide essential comfort and mobility assistance for people with limited physical movement. However, like all mechanical devices, they may encounter problems over time—particularly with the motor, which is a critical component responsible for reclining and lifting functions. One common question many users ask is: Can I replace the chair motor in my lift chair myself? The answer is yes, but with some important considerations.
Understanding the Chair Motor
Before attempting any replacement, it's important to understand what the chair motor does. In most lift chairs, the motor is a linear actuator that moves the chair into recline or lift positions. Some advanced models use dual motors, allowing independent movement of the backrest and footrest. A failing motor may show signs like slow response, strange noises, or complete non-functionality.
When to Consider a DIY Replacement
Replacing the motor yourself is feasible if:
You have basic DIY skills or experience with mechanical/electrical components.
The chair is no longer under warranty.
You have correctly identified the motor as the source of the problem.
You can access a compatible replacement motor.
However, if your chair is still under warranty, DIY replacement could void it. Always check the manufacturer’s policy before proceeding.
Tools and Parts You’ll Need
To replace a lift chair motor, prepare the following:
Replacement motor: Make sure it matches the model number of your original motor.
Screwdrivers/wrenches: To remove bolts and panels.
Multimeter (optional): To test the old motor or wiring.
User manual: For wiring diagrams or motor location (often found online if the original is missing).
Step-by-Step Replacement Guide
Unplug the Chair
Safety first—disconnect the chair from the power source to prevent electric shock.
Turn the Chair Over
Gently tip the chair onto its side or back to access the underside where the motor is typically located.
Locate the Motor
Find the linear actuator (usually mounted between the base and lift frame) and inspect how it's connected.
Disconnect the Wiring
Carefully unplug the motor's wiring connectors. Some connectors may have locking clips.
Remove the Motor
Unscrew or unbolt the motor from the chair’s frame. Take note of where and how it's attached.
Install the New Motor
Fit the new motor into place, aligning it exactly as the old one. Bolt it securely.
Reconnect Wiring
Plug in the wires and ensure connections are firm and correctly aligned.
Test the Chair
Set the chair upright, plug it in, and test all functions. Ensure smooth operation with no abnormal noises.
Common Challenges
Incompatible motor: Even slight differences in voltage, size, or pin configuration can cause issues.
Hidden fasteners or wiring: Some motors are difficult to reach without partial disassembly.
Electrical faults: Sometimes the issue lies in the remote, control box, or power supply—not the motor.
When to Call a Professional
If you're unsure about any step, or if the chair has complex electronics, calling a professional technician is safer. Improper installation could cause injury or further damage.

Yes, you can replace the chair motor in your lift chair yourself, provided you have the correct tools, a compatible motor, and a bit of patience. For many users, it’s a cost-effective way to extend the life of the chair. Just remember to follow safety precautions and double-check compatibility. If in doubt, professional help is always a good option.
