Diagnosis
The warming drawer has a separate control board and heating element. If the button presses but nothing activates, the issue is either a blown thermal fuse, a failed control board, or a disconnected wiring harness.
How to Fix It
Check the thermal fuse first—it's a common fail-point designed to cut power if the drawer overheats.
- Unplug the range.
- Remove the warming drawer by pulling it all the way out and lifting it up and off the tracks.
- Look near the heating element at the top of the drawer cavity for a small, white ceramic block with two wires (the thermal fuse).
- Test it for continuity with a multimeter. If it's open (no continuity), it's blown and needs replacement (part # DE96-01458A).
If That Didn't Work
If the fuse is good, the next likely culprit is the warming drawer control board, a small module mounted inside the console. You'll need to remove the control panel to access and test it.
Heads Up
The warming drawer is on its own circuit. Ensure you haven't accidentally turned off the dedicated 'Warming Drawer' circuit breaker in your home's electrical panel before diagnosing internal parts.
