Are you seeing the H5 on your LG stove display screen while trying to turn it off? This must be your first encounter with it and you’re probably wondering what LG stove H5 stands for.

The H5 is actually “HS,” which stands for “Hot Surface.” It is a “Temperature Sensor Error” code that appears on LG stoves or ranges when the cooktop temperature has risen beyond a certain level.

Keep reading this post to learn more, including what H5 means on a stove, what causes this error, and how to fix it!

Key Takeaway

Understanding the meaning of “H5” on LG stoves can help you utilize the self-cleaning feature effectively.
Always ensure the oven is empty before initiating the self-cleaning cycle to prevent any accidents or damage to cookware.
It’s normal for the oven to emit smoke or odors during the self-cleaning process as it burns off food residue.
Avoid opening the oven door during the self-cleaning cycle to maintain the high temperatures required for effective cleaning.

What Does H5 Mean on LG Stove? 

The H5 error code on any stove including the LG electric and gas ranges actually represents “HS” or “Hot Surface” Error. 

Here, the hot surface indicates the hotness of the cooktop surface. This may also indicate disconnection of your stove’s humidity sensor.

When you see this code on your stove’s display screen, it simply means that the stove’s temperature sensor has detected that your cooktop surface is too hot, and the temperature is higher than 150°F.

LG claims that even though the code is listed under their Error code list for customer preference, the H5 or HS is not a real error code and more like an indicator to alert the user that the cooktop is too hot to touch.

In most cases, this error indication will turn off as soon as the cooktop’s temperature reaches room temperature or somewhere below the 150°F range.

How Serious Is The H5 Error On A Stove?

The code itself is not serious but it indicates that the cooktop of your stove has reached the maximum (above 150°F) level, and it has become too hot to touch.

This means you should immediately stop cooking, turn off the stove, and let it cool down completely before turning it back on. 

Otherwise, if you continue to cook in such a state, it may damage your burner or the key elements of the stove. This can also lead you to experience a fire explosion on your stove due to extreme heat.

Therefore, even though the code is not a serious matter, you should still take the warning seriously and take proper action as needed.

What Causes the H5 Error On A LG Stove?

There are several reasons why the H5 code may appear on your LG stove. Among the most common causes are:

  • Too Hot Surface Temperature: The H5 code may appear if the cooktop temperature is too high, and the stove’s hot surface indicator light has been on for an extended period after the cooktop has been turned off.
  • Overusing: Using the stove for an extended period or at a high temperature can cause the appliance to overheat and trigger the H5 error code. 
  • Faulty Heating Element: Sometimes, even after the cooktop of the stove cools down, this error still remains. This can be due to a faulty heating element.
  •  Malfunctioning Temperature Sensor: This can also trigger the H5 code on your LG stove as the sensor won’t be able to measure your cooktop’s temperature correctly and will send the wrong information to the main control board.
  • Irregular Input Voltage: If the input voltage of your stove is not stable or within the normal range, this can also lead to the H5 error. It could be due to a sudden power surge at your home or if your stove is connected to an incompatible power source.
  • Switch or Relay Malfunction: The relay or switch is responsible for controlling or turning off and on the burner when the cooktop reaches a certain temperature. But if the relay or switch is faulty, it may not turn off the burner to cool off the surface heat and trigger the H5 error code. 
  • Compressor Coil Resistance: If the compressor coil in the outdoor unit has resistance, this can also cause the H5 code to appear on your LG stove.

How To Resolve H5 on An LG Stove?

If you’re experiencing the H5 error code on your LG stove, follow these steps to get rid of the code:

  1. The first step is to turn off the burner or unplug the stove from the power source. 

Wait at least 20 to 30 minutes until your stove’s cooktop cools down to room temperature. 

  1. Once the stove has cooled down and the surface is turned back to room temperature, the H5 error will automatically go away. But if the indicator still shows up:
  • Clear the code by pressing the “CLEAR” or “OFF” key.
  • Turn the circuit breaker off and wait at least 30 seconds before turning it back on.  
  1. If the problem persists, you need to check the temperature sensor for any signs of damage. If the temperature sensor appears to be damaged, you may need to replace it, and this below tutorial will help you do so:

  1. If the temperature sensor appears to be working correctly, you may need to check the relay or switch on your stove. 

Just remove the back panel of your stove and check the connections of the relay or switch. If the connections appear to be loose or damaged, you need to replace the relay or switch. 

If you want to perform this replacement yourself, just follow this easy and quick tutorial step by step:

  1. If the relay or switch looks in good shape or the connections are good too. You may try to test the compressor coil resistance to verify if there’s an issue with that.

  1. If the issue does not seem to be fixed or you don’t feel comfortable making these repairs yourself, it’s always best to contact a professional technician to inspect and repair the issue.
