Answer to continue safely
Is it safe to keep using?
Yes. A non-working hood light does not affect ventilation function. The hood can continue to be used for fan operation while the light issue is diagnosed and repaired.
Can I reset the code?
Yes. A circuit breaker reset may restore function if a transient fault caused the light circuit to latch off. More commonly, lamp replacement is needed — the reset alone is not sufficient.
When to stop immediately?
Stop if you notice: Stop troubleshooting and call service if replacing the lamp and fuse does not restore light function — control board replacement may be needed., Do not install a higher-wattage lamp than specified — fire risk from overheated socket..
Symptoms You May Notice
Pressing the light button produces no illumination
Activating the hood light control — whether a touch button or physical switch — does not turn on any of the LED or halogen lamps beneath the hood. The cooking surface remains dark.
One or more lights are out while others work
Some hood models have multiple light positions. If one lamp is out while others work, the failed lamp or its socket is the isolated fault. If all lights are out simultaneously, a control board, fuse, or wiring issue is more likely.
Light flickers before going out completely
In the days or weeks before complete failure, the light may flicker or cycle on and off intermittently — typical behavior of a lamp nearing end of life or a loose socket connection.
Light works only on one of two brightness settings
On DHD models with dual-brightness light control, one intensity level works while the other does not — pointing to the light dimmer circuit rather than the bulb itself.
Possible Causes
Burned-out lamp or LED module
The hood lamp — halogen on older models, LED on newer DHD and DHW models — has reached end of life and requires replacement with a Dacor-compatible lamp of the correct wattage and base type.
DIY PossibleBlown lamp fuse on the hood control board
Many Dacor range hoods protect the lamp circuit with a small inline fuse. A lamp that failed with a short circuit may blow this fuse, causing all lights to go dark even after the lamp is replaced.
DIY PossibleFailed light control board or dimmer circuit
The electronic light control circuit on the hood PCB can fail independently of the fan system, leaving the lamp circuit permanently open even with good bulbs installed.
Requires ProfessionalSafe Checks You Can Do
-
1
Replace the lamp with a correct-spec replacement
Consult your Dacor DHD, DHW, or DHI owner's manual for the correct lamp type and wattage. Turn off the hood at the breaker, allow any halogen lamp to cool for 10 minutes, then replace the lamp. For LED models, the LED module may be integrated — check the manual for the correct replacement part number.
Use only Dacor-specified lamp wattages. Installing a higher-wattage bulb can damage the lamp socket and void warranty.

2
Check for a lamp circuit fuse on the control board
With power off at the breaker, locate the hood control board (usually accessible by removing the grease filter and a cover panel). Look for a small glass or ceramic fuse near the lamp circuit. A visibly blown fuse (darkened glass, broken filament) should be replaced with the identical amperage and type.
Take a photo of the fuse before removing it to ensure you purchase the correct replacement.

3
Test the light switch or button for function
If the new lamp does not illuminate, confirm the light switch or touch button is registering. On DHD touch-control models, press and hold the light button for 3 seconds to ensure it is not locked out. Check if the fan and light share a control lock function.
Refer to the Dacor hood control panel guide for any lock or disable features that could prevent the light from activating.
When to Call a Professional
Contact a qualified technician if:
- New correct-spec lamp and replaced fuse still produce no light — control board light circuit has failed.
- Lamp socket is scorched or shows heat damage — socket and wiring replacement required.
- LED module is integrated with the hood assembly and is not user-replaceable on some DHI482 configurations — technician required.
