What Fan Wont Turn Off means on your Dacor range hood (dacor range hood fan wont shut off)
Dacor assigns no code to this on a range hood, which is why this reads as a symptom and not as a decode. A fan that keeps running regardless of the button pressed, or that will not respond to the off command, points to the switch or control circuit rather than the motor, since the motor is simply doing what it is being told. This is different from the hood turning itself on unexpectedly (covered on its own symptom page), where an overheat sensor is the more likely cause.
Symptoms
The point of the list below is to stop you replacing the wrong part of a range hood, because Fan Wont Turn Off imitates other Dacor range hood problems closely.
- The fan continues running no matter which speed or off button is pressed.
- Cutting power at the wall switch or breaker is currently the only way to stop it.
- The control panel lights may stay lit even after attempting to turn the fan off.
- The problem started after a power surge, spill on the control panel, or recent cleaning.
Common causes
More than one thing can produce Fan Wont Turn Off on a range hood, so the causes below are ordered by how often they turn out to be responsible on a Dacor range hood.
- Stuck control button or switch — moisture or grease can hold a physical or touch button in a pressed state.
- Failed relay in the control board — the relay that should cut power to the motor stays closed.
- Water intrusion on the control panel — cleaning liquid seeping behind the panel can short a control input.
- Wiring failure sending a constant run signal — a damaged wire shorted to the run circuit overrides the off command.
Troubleshooting steps you can try
These checks cost you nothing on a range hood and often end the problem there; anything harder on a Dacor range hood needs a technician.
- Cut power at the breaker if the fan will not stop, rather than leaving it running indefinitely.
- Let the control panel dry fully if a recent spill or cleaning is the likely trigger.
- Once dry, restore power and test whether the off button now responds normally.
- Avoid pressing buttons repeatedly or forcing the switch, which can worsen a stuck-contact problem.
- Book a technician if the fan restarts running as soon as power is restored, since that points to an internal control failure rather than moisture.
Parts a technician may replace
Diagnosis on your Dacor range hood usually points at the control switch, wiring harness, and control board. Nothing is ordered for the range hood until the failing part is confirmed on the range hood itself.
When to call a technician
A technician tests the control board relay and switch inputs, since a fan that will not stop is treated as a control failure requiring the panel to be opened safely. Medium severity means the range hood can wait, but a recurring Fan Wont Turn Off on a range hood should be diagnosed rather than ignored. Repairs to your range hood are carried out by independent technicians using genuine parts, with 30 days of labor cover.
