How to Replace a Recliner Power Supply
Replacing a recliner power supply is one of the simplest repairs on an electric recliner or lift chair. No tools are required in most cases. This guide explains how to confirm the power supply is the fault, how to choose the correct replacement, and how to fit it safely. If you are unsure which system is fitted to your chair, start with our guide to identifying Okin, Kaidi, Limoss and Dewert recliner systems.
Before You Start: Confirm the Power Supply Is the Fault
A failed power supply is the most common reason an electric recliner stops responding. Before ordering a replacement, confirm the fault is in the power supply and not the wall outlet, cable or chair.
- Test the wall outlet with another device to confirm mains power is present.
- Check the power supply cable for visible damage, cuts or kinks.
- Check the indicator light on the power supply if one is fitted — no light usually means the supply has failed.
- Feel the power supply body — if it is unusually hot or has a burnt smell, it has failed.
- If a known working power supply is available, test it in place of the existing supply to confirm the fault.
How to Choose the Correct Replacement Power Supply
The replacement power supply must match three key specifications: output voltage, amperage and connector type. Use our recliner connector and plug identification guide to check the plug before ordering.
- Output voltage: Most Australian recliners use a 29V DC power supply. Check the label on your existing supply for the output voltage.
- Amperage: Common ratings are 2AMP and 3AMP. A higher amperage replacement is safe to use in place of a lower-rated supply. Do not use a lower-rated supply in place of a higher-rated one. Dual-motor recliners and chairs with USB or LED accessories may require a 3AMP supply.
- Connector type: The output connector must match the input socket on your chair’s control box or cable. Most Australian recliners use the standard OL plug — a round two-pin connector. Confirm the connector matches before ordering.
What You Will Need
- Replacement power supply (correct voltage, amperage and connector)
- No tools required for most standard power supply replacements
Step-by-Step: How to Replace the Power Supply
- Unplug the existing power supply from the wall outlet.
- Disconnect the power supply cable from the chair or control box by pulling the connector straight out. Do not pull by the cable.
- Compare the old and new power supply — confirm the output voltage, amperage and connector type match before proceeding.
- Connect the new power supply to the chair or control box by pushing the connector firmly into the socket until it seats fully.
- Plug the new power supply into the wall outlet.
- Test the chair by pressing the handset buttons and confirming all functions operate correctly.
- Check the indicator light on the new power supply if one is fitted — it should illuminate when connected.
After Replacement: What to Check
- Confirm all recliner functions operate correctly — recline, footrest and lift if applicable.
- Check that the new power supply does not become excessively hot during normal use.
- Route the cable neatly to avoid pinch points or tripping hazards.
- Dispose of the old power supply responsibly — check your local council’s e-waste disposal options.
Common Power Supply Replacement Mistakes
- Wrong voltage: Using a power supply with a different output voltage can damage the control box or motor. Always confirm the voltage matches.
- Undersized amperage: A 2AMP supply in a dual-motor or feature-rich chair may overheat under load. Match or exceed the original amperage rating.
- Wrong connector: A power supply with the correct voltage but the wrong connector will not fit. Confirm the connector type before ordering.
- Pulling by the cable: Always disconnect by gripping the connector body, not the cable. Pulling by the cable can damage the connector or internal wiring.

Frequently Asked Questions
Do I need a technician to replace a recliner power supply?
No. Replacing a recliner power supply requires no tools and no electrical work. It is a straightforward plug-and-play replacement provided the voltage, amperage and connector match.
Can I use a 3AMP power supply to replace a 2AMP supply?
Yes. A higher amperage rating means the supply can deliver more current if required. The chair will only draw the current it needs. Using a 3AMP supply in place of a 2AMP supply is safe provided the voltage and connector match.
My new power supply gets warm during use. Is this normal?
Some warmth is normal. A power supply that becomes too hot to touch, emits a burning smell or shuts off during use should be replaced. If the new supply overheats, confirm the amperage rating is sufficient for your chair.
How long should a recliner power supply last?
A quality recliner power supply should last many years under normal use. Premature failure can be caused by power surges, overloading, physical damage to the cable or connector, or operating in a hot environment.
