For new fridges, it’s possible showroom (demo) mode is on. But, can also happen if someone was tinkering with the control panel on your fridge. Demo mode is used for fridges being displayed in a store.

When it’s on the lights come on, and all the buttons work, but cooling is disabled. It requires a unique combination of buttons to turn it on and off. Refer to your owners manual to see how to turn demo mode on and off on your specific LG fridge make and model. There is also what is called Sabbath mode, ensure this is not enabled using the instructions in your owner’s manual.

Finally, if it still won’t work after trying these steps get in touch with LG support. There is an internal fault that requires a repair technician to fix. If you have electronics experience, or experience repairing appliances then it can be fixed yourself.

This is done by opening up your fridge and testing each of the components using a voltmeter. And inspecting any components for mechanical damage. Then replacing any of the components that have failed with new ones by ordering them online or from LG.

All fridge freezers have a fan that blows cool air into the freezer and another fan that blows cool air from the freezer into the fridge. Whereas, standalone fridges only have one fan responsible for blowing cool air into the fridge.

Top Reasons Why Your LG Refrigerator Fan Is Not Working

All fridge freezers have a fan that blows cool air into the freezer and another fan that blows cool air from the freezer into the fridge.

It’s very simple to fix some of these issues. Whereas, others require a repair technician, unless you have experience working with electronics. Below, I will cover how to troubleshoot each of the issues that cause the fan on your fridge not to run for each of the main fridge brands, such as LG, and GE.

1. Cooling mode is turned off

Virtually all fridges have cooling mode that can be turned on and off. If someone in your household has been tinkering with the digital display they may have accidentally disabled cooling mode. On many fridges cooling is turned off when the power is disconnected to your fridge. 

This can happen if the fuse at the switch board for your home is triggered due to a power surge. Or, if you moved your fridge to a different part of the house. It’s very easy to check if your cooling mode is on. 

There is typically a dedicated button on the LCD display for a fridge. On fridges without an LCD display there is a decent sized switch like a light switch. It’s typically located around the edge or on the interior of your fridge. 

If you can’t locate it, refer to your owners manual to see where it’s located. It can be a paper version, or an online version. You can typically download an online version from your fridge manufacturers website.

2. It’s in showroom mode or Sabbath mode

Showroom mode, also called demo mode, is used when a fridge is in a store. It enables all of the functionality of a fridge to work, but does not cool your fridge. And therefore the fan never runs. 

It may have been left on by mistake when you brought your fridge. Or, it may have been enabled accidentally. Sabbath mode is closely related.

It stops a fridge from cooling on the Sabbath, which, as you may know, is a Saturday. Refer to your owners manual to see how to enable and disable showroom and Sabbath mode. 

3. An internal component is faulty

There are various internal components on a fridge. These include the internal computer, the fan, thermostat, and condensers. These are all closely related, and if one is not working it can cause one of the others to not function. 

The fan itself can also be faulty. Unless you have experience working on electronics, or appliances, it’s best to have a repair technician take a look at it.
