Thermador Refrigerator Lights Not Working

Thermador refrigerators are one of the most reliable brands in the industry, but occasionally they can have issues with their lights. If your Thermador refrigerator lights are not working, chances are there could be a simple fix. Fortunately, many of the problems you may encounter with Thermador refrigerator lights can be resolved without calling out a repair technician. Understanding what causes refrigerator lights to not work and learning some basic troubleshooting steps may help you get back to a fully functioning fridge quickly.


If your Thermador refrigerator lights are not working, it can be a sign of a problem with the appliance. This article aims to help you diagnose and fix the issue so that your refrigerator will be back up and running in no time.

Check the Light Bulbs

The first step is to check the light bulbs themselves. Make sure that they are properly screwed in or plugged in, and that they are still working. You can test them by removing them from their sockets and replacing them with working bulbs from another fixture. If the other bulbs work, then you know that your original bulbs were the issue and simply need to be replaced.

Check the Power Source

If the light bulbs themselves appear to be in good condition, then it could indicate an issue with the power source. Check if there is power running to your refrigerator by testing it with a voltmeter or plugging something else into its outlet to see if it works. If there is no power going to your fridge, then you may need to replace its outlet or reset any circuit breakers associated with it.

Look for Obstructions

Another potential cause of your lights not working is an obstruction blocking them from functioning properly. Look inside and outside of your refrigerator for any items that could be blocking the light fixtures or preventing them from turning on when opened. If any items are blocking the lights, simply move them away so that they can turn on as normal when you open the door or drawer again.

Check Your Thermador Refrigerator’s Control Panel

The control panel on your Thermador refrigerator may have a setting that turns off all of its lights when activated. Be sure to check this setting before attempting any other repairs as it could be what’s causing this issue in some cases. Simply switch back to ‘on’ if this is indeed what has happened and then see if your lights start working as normal again.


These are some of the most common causes of why Thermador refrigerators lights may not be working properly. Before calling an appliance repair service, make sure to try these steps first as they may help you identify and fix the problem on your own without any additional costs!
