The oven door liner (DG94-00524A) is a vital part of your Samsung gas range, covering the inner part of the oven door and providing a frame for the door window. If the inner part of your oven door is damaged or compromised, replacing it with this genuine Samsung part can help maintain the efficiency of your appliance. Before installation, shut off electrical power to your range and wear work gloves for safety. Always verify your model number for compatibility before purchasing.
