Summary

LG LTG4715BD code H5 means cooktop temperature is greater than 150°F (HS hot-surface indicator; not an error code). This guide explains the likely causes, the safest first checks, and when support or service is the better next step.

What to do first

  1. Read the display message in the context of the current cycle or operating mode.
  2. Exit the mode, clear the option, or let the current function finish if that is how your model handles the message.
  3. Restart the appliance once if the display should have cleared but remains on screen.

What H5 means

Cooktop temperature is greater than 150°F (HS hot-surface indicator; not an error code). On the LG LTG4715BD, this code relates to the range cooker and should be interpreted together with how the appliance is behaving right now.

Common symptoms

  • The range cooker displays H5 instead of normal status information.
  • The current cycle, function, or startup sequence may stop, pause, or behave differently than expected.
  • The same code may return after a reset if the underlying issue is still present.

Most likely causes

  • The appliance is reporting an active mode, reminder, or temporary operating condition.
  • A recent button press, feature selection, or cycle state triggered the display message.

Deeper checks before service

  1. Check the user manual or model-specific support guidance for the exact meaning of the displayed state.
  2. Confirm no child-lock, Sabbath mode, delay timer, or special feature is still active.
  3. If the same code remains after the normal mode should have ended, move to support or service advice.

Safety warnings

  • Do not force resets repeatedly if the appliance is still mid-cycle or in a protected state.

When to contact support

Contact support if H5 stays visible after the normal mode should have cleared, or if the range cooker will not return to normal operation.

FAQ

Can H5 clear after a reset?
Sometimes a temporary glitch clears after one full reset, but a repeated return usually means the same underlying issue is still there.
Should I keep using the appliance if it works again briefly?
Only if the code stays away and the appliance behaves normally. If the same code comes back, stop and move to service or more targeted diagnosis.

What to record before LG support or repair

  1. Photograph the full display and the product label or rating plate.
    ExpectedYou can confirm the exact model and avoid support or parts quotes against the wrong product variant.
  2. Note whether the appliance was idle, starting up, heating, filling, draining, cooling, or finishing a cycle when the code appeared.
    ExpectedYou have the timing detail that usually matters most in fault triage.
  3. Write down any recent changes such as a power interruption, filter clean, leak, unusual noise, smell, moved installation, or repeated manual reset attempts.
    ExpectedSupport can separate a recent event from a longer-running repeat fault faster.

Next actions if H5 keeps coming back

If H5 returns after one clean restart and the user-accessible checks above, treat that as a repeat fault. The safest next move is to compare the model hub, confirm the official manual-safe checks for this device, and then escalate with a clear symptom record instead of opening panels or replacing parts blind.
