If your model has LED light assemblies, and the light is out in the freezer while the light in the fridge is dim, you'll need to change the light assembly in the freezer. Using knock-offs or aftermarket parts, like those found on Amazon, could be the reason why the LED lights burn out frequently. You can find OEM parts at www.SearsPartsDirect.com
, just enter your full model number.
If your model doesn't had LED lights, you could be using the wrong wattage bulbs, or the power supply voltage may be too high.
If you need a repair, you can call Sears Home Services at 1-800-4-MY-HOME.
Hope this helps!
