Risk level

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

If your LiftMaster 8500W, 98022, or 98032 wall-mounted jackshaft opener flashes 5 UP and 5 DOWN (Code 5-5), it requires a plugged-in, paired myQ Remote LED Light before it will close via the myQ app, schedules, or Timer-to-Close.

Safety first

Stop and check this first

  • The paired remote light is a safety requirement that warns people near the doorway before an unattended close: never attempt to bypass it, and keep the doorway clear.

Safe checks you can perform

  • Confirm 5 UP and 5 DOWN arrow flashes and normal wall button operation
  • Confirm the myQ Remote LED Light is installed and plugged into a live outlet
  • Reprogram the myQ Remote LED Light if opener memory was cleared

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Install, power, and pair the myQ Remote LED Light to resolve Code 5-5
  • Do not attempt this professional task: Inspect and replace the logic board if Code 5-5 appears on LJ8900W or LJ8950W

What a technician must be able to justify

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Install, power, and pair the myQ Remote LED Light to resolve Code 5-5

    What they doOn residential LiftMaster 8500W, 8500WRGD, 8500WLA, 98022, or 98032 openers, the technician verifies that a compatible myQ Remote LED Light is properly mounted, powered, and programmed to the opener so unattended operation is enabled.

    They must show youthe paired myQ Remote LED Light responding with the opener and a completed myQ or Timer-to-Close test.

    In writingresidential jackshaft model, confirmed remote light installation and pairing, and clearance of Code 5-5.

  2. Inspect and replace the logic board if Code 5-5 appears on LJ8900W or LJ8950W

    What they doIf Code 5-5 occurs on a Light-Duty Commercial LJ8900W or LJ8950W operator (or continues on a residential unit despite a working, paired remote light), the professional inspects the unit and replaces the logic board as directed by the chart.

    They must show youthe verified model label and restored operator response after replacing the logic board.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Confirm 5 UP and 5 DOWN arrow flashes and normal wall button operation

    No special tools

    Who:
    you, checking the UP and DOWN arrows on the LiftMaster jackshaft opener with the door in view.
    How:
    count 5 flashes on the UP arrow and 5 flashes on the DOWN arrow, and verify that the wall control button and handheld remotes still move the door even though myQ app close or Timer-to-Close does not.
    Result that matters:
    confirm that the opener is blocking only unattended closing commands under diagnostic Code 5-5.
    If the wall control also fails to move the door or the flash count is not 5 UP and 5 DOWN:
    match the exact flash count in the chart.
    If wall and remote controls work while unattended close triggers 5 UP and 5 DOWN flashes:
    check the remote light power next.
    Evidence to keep:
    confirmed 5 UP and 5 DOWN flash count and normal door response from the wall control.

  2. Confirm the myQ Remote LED Light is installed and plugged into a live outlet

    No special tools

    Who:
    you, checking the remote work light supplied with your 8500W, 98022, or 98032 opener.
    How:
    make sure a myQ-compatible Remote LED Light is installed and plugged into a working electrical outlet; if you choose not to use the remote light, turn off schedules and automations in the myQ app.
    Result that matters:
    restore power to the required remote light or disable unattended schedules when operating without it.
    If plugging the remote light into a powered outlet clears Code 5-5:
    test an app or TTC close while watching the doorway.
    If the remote light is plugged into a live outlet but Code 5-5 remains:
    reprogram the light to the opener next.
    Evidence to keep:
    verified outlet power for the myQ Remote LED Light or disabled schedules in the myQ app.

  3. Reprogram the myQ Remote LED Light if opener memory was cleared

    No special tools

    Who:
    you, following the owner pairing steps for the remote light without opening the motor housing.
    How:
    if the garage door opener memory was previously cleared, program the myQ Remote LED Light to the opener again and test whether myQ Smartphone Control, scheduled closing, and Timer-to-Close operate the door.
    Result that matters:
    re-establish the wireless pairing required before the opener allows unattended closing.
    If reprogramming the remote light restores myQ app closing and Timer-to-Close without 5-5 flashes:
    keep the pairing record.
    If Code 5-5 persists after pairing the light, or your unit is a Light-Duty LJ8900W/LJ8950W model:
    request technician service.
    Evidence to keep:
    remote light pairing outcome and whether app-based or TTC commands close the door afterward.

What it means

Chamberlain Group's official diagnostic pages for LiftMaster wall-mounted jackshaft openers 8500W (RJO70), 8500WRGD, 8500WLA, 98022 (RJO101), and 98032 define Code 5-5 (5 UP arrow flashes and 5 DOWN arrow flashes) as 'Remote Light Required for Unattended Operation.' As a safety precaution, the opener ignores unattended commands (myQ app close, scheduled close, smart-home automations, or Timer-to-Close TTC) until a compatible myQ Remote LED Light is plugged in and paired, while the wall control and remotes still work. Light-Duty models LJ8900W and LJ8950W do not require this light. Other models may differ, and Code 5-5 alone never proves a hardware failure.

Warnings and stop conditions

  • Mediumsource verified

    The paired remote light is a safety requirement that warns people near the doorway before an unattended close: never attempt to bypass it, and keep the doorway clear.

Symptoms and causes

Probable causes · in order

  • myQ-compatible Remote LED Light not installed or unpluggedCommon

    LiftMaster notes that residential wall-mounted jackshaft openers will not execute Timer-to-Close or myQ app closing commands unless the compatible remote light is installed and plugged into power.

    Evidence: Garage Door Opener Diagnostic Codes and UP/DOWN Flashing Lights · Diagnostic Codes: Wi-Fi Residential and Light-Duty Commercial Jackshaft Operators

  • Remote light pairing lost after clearing opener memoryPossible

    Although remote lights are paired during manufacturing, the Code 5-5 guide explains that clearing the opener's memory erases that link until the remote light is programmed to the opener again.

    Evidence: Garage Door Opener Diagnostic Codes and UP/DOWN Flashing Lights · Diagnostic Codes: Wi-Fi Residential and Light-Duty Commercial Jackshaft Operators

  • Logic board fault on Light-Duty Commercial LJ8900W or LJ8950W unitsLess common

    The Wi-Fi jackshaft diagnostic chart states that Light-Duty models (LJ8900W and LJ8950W) do not require the myQ Remote LED Light, so encountering Code 5-5 on those models points to the logic board.
