I'm sorry to hear you're having issues with your SMH7185STG. If the microwave heats but will not turn, try removing the glass tray and roller guide ring and washing them thoroughly in soap and warm water. Wipe down the inside of the microwave to remove any grease or residue that may have deposited over time. Replace the roller guide ring and glass tray. If the turntable still won't rotate, or if the microwave does not heat, it will 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.
