I'm sorry to hear you're having this issue. E-28 is a functional error indicating there may be a shorted oven sensor. Press the CLEAR/OFF pad and restart the oven. If the problem persists, disconnect all power to the range for at least 30 seconds and then reconnect the power. If this does not solve the problem, your FTQ352 may require service. Please submit your contact information through the link below, or call 800-SAMSUNG to speak with an agent who can assist you.
