Question about Maytag 15 cu. ft. / 425 liter Upright Freezer MQU1556A
Click Here for your user manual=> MQU1556AEW.pdf The settings for defrost should come automatically every 12 hours. You may test the defrost timer that appears to be behind the kick plate at base and front bottom of refrigerator by removing the kick plate first and using a flathead screwdriver turn slowly clockwise until compressor stops. After a few minutes you should be able to hear a crackling noise or sizzle by opening the door and listening. Leave the timer like that for up to 35 minutes and if the freezer does not start on its own the the timer is not working properly and will need replaced.
