Amana Range vent hood turning on by itself

When an Amana range vent hood is turning on by itself, the thermostat is the most likely cause. Some vent hoods have a thermostat that automatically starts the blower when the hood gets hot, then shuts it off after the temperature drops. Check your owner's manual and wiring diagram to confirm whether your Amana range vent hood has this feature. If the blower or lights turn on and off randomly, the control board may have burnt relay contacts or an internal short. A worn touchpad can also intermittently close a circuit and signal the hood to start. Next, inspect the user control and display board by testing each control panel button for proper response. The main control board can cause the same symptom, while a faulty control module is less common and should be considered only after the touchpad, control panel, and boards are tested. Before ordering an Amana range vent hood thermostat, touchpad, control board, or control module, enter your model number to find the exact replacement part for your specific range vent hood.

01 - Amana Range Vent Hood Thermostat

If the temperature in the hood gets hot there may be a thermostat that will automatically turn on the vent blower until the temperature cools down. Check the owner's manual and /or the wiring diagram to see if your vent hood has this feature.

02 - Amana 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.

06 - Amana 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.
