Amana Oven fan won't turn off

An Amana oven fan that won't turn off may have a failed oven control board, main control board, or a stuck relay that keeps sending power to the fan motor. These control board problems are uncommon, so check the wiring diagram and thermostats before replacing a board. In some cases, the oven cooling fan keeps running for more than an hour after the oven is turned off, especially after high-temperature cooking. This cooling period is normal while the range, stove, or oven components cool down. If the oven fan continues running after the oven has cooled completely, test the high-limit thermostat with a multimeter. A defective high-limit thermostat or thermostat may continue sending voltage to the fan circuit. If a thermostat has no continuity when it should, or shows continuity at every temperature, replace it. For an Amana oven fan not turning off, disconnect power before testing or servicing internal parts. Enter your model number to find the exact replacement oven control board, main control board, high-limit thermostat, thermostat, or fan motor for your specific Amana range, stove, or oven.

01 - Amana Range/Stove/Oven Oven Control Board

The oven control board has relays that regulate power to the bake, broil and fan circuits according to the user settings and sensor input. If one of these relays shorts out, the control board may send continuous voltage to the oven fan. However, this is rarely the case. Before replacing the control board, first check the oven thermostats. If an oven thermostat fails, it may cause the oven fan to run continuously.

02 - Amana Range/Stove/Oven Control Board

If the oven fan is not shutting off, a relay on the control board may be stuck closed sending constant power to the oven fan. Check the wiring diagram first before replacing the board. Control boards are often misdiagnosed.

03 - Amana Range/Stove/Oven Main Control Board

The main control board has relays that send voltage to the fan motor. If one of the control board relays shorts closed, the control board may send continuous voltage to the fan. If the fan continues to run after the oven is turned off and cooled down, the main control board is likely defective. If the control board is defective, replace it.

04 - Normal Cooling Down Period

The oven cooling fan may run well over an hour after the oven is shut off to cool down the components. The hotter the temperature was set the longer the cooling fan needs to run to cool off the oven. This is normal.
Less Common

05 - Amana Range/Stove/Oven High Limit Thermostat

The high limit thermostat sends voltage to the oven fan as the oven heats up. If the high limit thermostat is defective, it may keep sending voltage to the oven fan after the oven has cooled down. To determine if the high limit thermostat is at fault, use a multimeter to test the thermostat for continuity. If the high limit thermostat does not have continuity, replace it.

06 - Amana Range/Stove/Oven Thermostat

The thermostat sends voltage to the oven fan as the oven heats up. If the thermostat contacts are stuck closed, the thermostat may continue to send voltage to the oven fan after the oven has cooled down. To determine if the thermostat is at fault, use a multimeter to test the thermostat for continuity. If the thermostat shows continuity at any temperature, this indicates that the thermostat is defective. If the thermostat is defective, replace it.
