1 Platinum Lift Power Recliner with 6-Motor Massage & Heat WARNING To reduce the risk of injury: Do not attempt to disassemble or service the actuators. No serviceable parts are inside. Introduction: This troubleshooting guide lists the possible causes in the order that are easiest to check, followed by the part most likely to be the cause. La-Z-Boy always recommends to test the potential failed part with a good, known working part, or through the use of a multimeter. When testing the system with a good, known working part, always follow these steps: 1. Unplug the power cord from the wall outlet. 2. Disconnect the power supply (transformer) from the connector behind the recliner. 3. Remove the (2) 9-volt batteries from the power supply, if installed. 4. Wait 60 seconds. 5. Test the system using a good, known working part. 6. When reconnecting the system, reverse the steps above. Install (2) quality name brand 9-volt batteries, connect the power supply to the chair and then plug the power cord into a working outlet. working at all, the LED light on the power supply is illuminated (or flashing) and the backlight on the hand wand works when a button is pressed. duty cycle has been activated. These features have a 50% duty cycle. not connected to the cable bundle, at the back of the chair. Allow the chair to rest for 10 minutes. After 10 minutes of continuous operation of the 1PL lift and recline features, allow the features to rest for 10 minutes to avoid activating the duty cycle lock out. When the duty cycle has been activated, the chair will not operate at the maximum time period for 10 minutes. Make sure the power supply is properly connected to the cable bundle connector at the back of the chair. Make sure the connectors are fully seated and locked. The system has experienced an over current. The 1PM is designed for a single occupant not exceeding 350 lbs. Stop pressing the button or toggle and remove excess load. If the system is not overloaded, check for a short circuit or ground fault. The lift / recline actuator is not connected. Make sure the lift / recline actuator is connected and fully seated to the master control module. Test with a good, known working power supply. If the unit works, replace the power supply.

The back recline and lift features work, but the legrest does not move or it moves slower than normal. A connection has not been made or has come apart. Check all connections. Make sure the legrest actuator is connected to the legrest extension cable, and the legrest extension cable connected to the master control module. Make sure the connections are fully seated and secure. Install legrest actuator extension cable if missing. (continued on page 4) The legrest actuator is connected directly to the master control module. The legrest actuator must be connected to the legrest extension cable, then the legrest extension cable must be plugged into the master control module. Install the legrest extension cable. 3 of 11

9 The massage feature is activated when the actuators are running. module (MCM) is Replace the master control module. The backlights on the hand wand are flashing. The auto homing feature has been interrupted. Unplug the power transformer from the electrical outlet, wait at least (3) seconds, then plug the power transformer directly into the power outlet. The chair will start the auto homing function again when it's plugged in. OR Press and release one button or the toggle on the hand wand. This will close the legrest, if extended. Then, press and hold the RECLINE button to lower the chair in a descending motion, which allows it to detect its position in the cycle. Once the chair identifies its position, the backlights stop flashing and the legrest function is available the chair is in normal operation The backlights on the hand wand are flashing or are illuminated with very low intensity. The system is in diagnostic A failure has been found. Determine if the diagnostic mode was activated. With no occupant in the chair, simultaneously pressing and holding down on the left side (or return side) of the BACK button and the LEGREST button, while pressing and holding down on the round RECLINE button for about 20 seconds, starts the self diagnostic If activated, inspect the connections of the failed part, which is where the system stopped once the diagnostic mode started. Make sure the connections are fully seated and secure, with no damaged wires or connectors. If properly connected and no visible damage noted, replace that part. module (MCM) is Replace the master control module. (continued on page 10) 9 of 11

10 The backlights on the hand wand are flashing or are illuminated with very low intensity. The auto homing feature has been interrupted. Unplug the power transformer from the electrical outlet, wait at least (3) seconds, then plug the power transformer directly into the power outlet. The chair will start the auto homing function again when it's plugged in. OR Press and release one button or the toggle on the hand wand. This will close the legrest, if extended. Then, press and hold the RECLINE button to lower the chair in a descending motion, which allows it to detect its position in the cycle. Once the chair identifies its position, the backlights stop flashing and the legrest function is available the chair is in normal operation During a power interruption, the battery backup does not work. Quality batteries are not installed in the power supply or the batteries are drained. Install two new, good-quality name brand 9-volt batteries in the power supply. The seat felt like it was falling when the chair was being returned from the reclined position. One or both of the extension springs that close the legrest are missing or damaged. Replace the missing or damaged extension springs. The legrest deck is loose. The clevis mount on the drive rod support link is Replace the clevis mount. A click or shudder is felt when the chair is fully reclined. The lift sleeve on the support shaft is loose and rotating on the inside arm assembly. Put two staples at the top of the lift sleeve to prevent it from turning when the mechanism moves. Lift Sleeve Staples (continued on page 11) 10 of 11

11 A click or shudder is felt when the chair is fully reclined. The glides on the metal base are missing. Install the base glides. Glide The legrest will not close or is droopy. The drive rod clevis has rounded out. Replace the drive rod clevis. There is excessive motion between the inner and outer body of the chair, or the chair feels like it is slipping or shifting while reclining the back. The glide assembly in the body side is missing on one or both sides. Install the glide assembly. Note: Each body side must have one glide and one washer. Insert a washer if one is missing.
