Kenmore Range Hood CONTROL-DEAD Error: Touchpad or control panel unresponsive
The kenmore range hood control-dead error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Range Hood Code CONTROL-DEAD Mean? CONTROL-DEAD is a behavioral symptom code for the condition where the control panel of a Kenmore Elite range hood […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A completely dead control panel means the hood cannot be operated — no fan, no light, no extraction. Do not attempt to bypass the control board to operate the fan motor directly. The hood is not usable until the touchpad or board is repaired.
Can I reset the code?
Yes. A two-minute full power-drain breaker reset can clear transient processor lockups on Kenmore Elite boards. If the panel remains dead after the reset, the touchpad membrane, thermal fuse, or control board must be replaced — no further reset will help.
When to stop immediately?
Stop if you notice: Control panel is completely dead and breaker reset does not restore any function — do not use the hood, Any button activates the fan or light erratically and unpredictably — risk of fan running unattended.
Symptoms You May Notice
Some touchpad buttons respond while others do not
When certain buttons on the Kenmore Elite control panel activate functions while others are dead to any input, the touchpad membrane itself has failed at those button positions — the main control board is typically still functional.
Entire control panel is unresponsive — no fan, no light, no display
When no button on the control panel produces any response and the hood appears completely dead despite confirmed power at the circuit breaker, the main control board, a blown thermal fuse, or a failed power supply to the board is the likely cause.
Control panel responds erratically — buttons activate wrong functions
Pressing the fan speed button activates the light, or functions activate on their own without input — this erratic behavior indicates moisture or grease has infiltrated the touchpad membrane, creating phantom electrical contacts.
Control panel briefly wakes after a power cycle then goes dead again
Flipping the breaker restores momentary response to the touchpad for a few seconds or minutes before it locks up again, typical of a control board that is overheating or a thermal fuse cycling on the edge of its trip point.
Possible Causes
Failed or moisture-contaminated touchpad membrane
The flexible circuit membrane behind the control panel buttons degrades from repeated pressing, heat cycling, and grease vapor infiltration. Individual button contacts open permanently or short together, causing dead zones or phantom activation.
DIY PossibleBlown thermal fuse cutting power to the control board
Kenmore Elite hoods include a thermal fuse in the power supply circuit as a safety device. If the hood overheats — from a motor stall or heavy grease fire — the fuse opens and removes all power from the control board. A multimeter continuity test confirms a blown fuse.
DIY PossibleFailed main electronic control board
The control board processes all button inputs and drives the fan motor and lights. If the board's processor, relay drivers, or power regulation circuitry has failed, the entire panel becomes unresponsive. An electrical surge is a common precipitating event.
Requires ProfessionalSafe Checks You Can Do
-
1
Reset power at the circuit breaker and wait two full minutes
Turn the range hood's dedicated circuit breaker off and leave it off for two full minutes to allow all capacitors on the control board to discharge completely. Restore power and test all control panel buttons. On Kenmore Elite models, a full power-drain reset can clear transient software lockups in the control board processor.
If the hood is plugged into an outlet rather than hardwired, unplug the power cord for two minutes instead of using the breaker. Plug back in and test — this achieves the same complete power drain.

2
Test the thermal fuse for continuity
Turn the hood off at the breaker. Remove the hood's top access panel (typically two screws on the back edge). Locate the thermal fuse — a small cylindrical component in-line with the power supply wiring, often near the control board. Disconnect the fuse and test it with a multimeter set to continuity or resistance. A functional fuse shows continuity (near-zero resistance); an open fuse shows no continuity and must be replaced.
Thermal fuses for Kenmore range hoods are inexpensive (typically $5–15) and are available from AppliancePartsPros and Repair Clinic by model number. Always replace with an identical amperage and temperature rating.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Thermal fuse tests as open and a replacement fuse blows again within days — indicates an underlying overcurrent fault
- Control board shows visible burn marks, bulging capacitors, or charred traces on inspection
- Touchpad tests as defective but the replacement touchpad also fails to respond — board is not powering the touchpad correctly
