The temperature in your FTQ353 has been preset at the factory. If your food is undercooking, it may be an indication that the thermostat needs to be adjusted. Please see the section "Thermostat Adjustment" on page 35 of your FTQ353 User Manual. If this does not resolve the issue, or if you find that the ±35°F adjustment is not enough to enable your food to cook correctly, it may require service. To initiate service through Samsung, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
