Dacor Range vent hood turning on by itself

If your Dacor range vent hood is turning on by itself, the thermostat is the most likely cause. Some hoods have a temperature-sensitive thermostat that automatically starts the blower when heat builds up, then shuts it off after the hood cools. Check your owner's manual or wiring diagram to confirm whether this feature is normal. If the blower or lights turn on and off randomly, a failing control board may have burnt relay contacts or an internal short. The touchpad is another common cause because a worn button can close the circuit intermittently and send an unintended signal. A faulty user control and display board can cause the same problem, especially if some control panel buttons do not respond correctly. The main control board or control module may also be shorting, but test the thermostat, touchpad, and control panel first. Disconnect power before testing or replacing parts. Enter your Dacor range vent hood model number to find the exact thermostat, control board, touchpad, user control and display board, or control module for your appliance.

02 - Dacor Range Vent Hood Control Board

The control board has relays that send power to the fan and lights. If the contacts in the relays become burnt, or the board is shorting out, they may make contact intermittently. If the fan or lights are turning off and on the control board may be bad.

03 - Dacor Range Vent Hood Touchpad

When the touchpad buttons are pressed a circuit is closed sending a signal to the control board. If the button is worn it can cause the circuit to close intermittently, turning on the hood.

The buttons on the user control and display board may be only intermittently activating. To determine if the control and display board is defective, try pressing each of the buttons on the control panel.

06 - Dacor Range Vent Hood Control Module

The control module receives inputs from the control panel switches to turn the lights and blower on and off. If the control module shorts out, the blower or lights may go on and off randomly. Because this is not a common problem make sure the control panel and switches are tested before replacing the control module.
