On approximately 117,157 models of Samsung microwaves manufactured between May 2000 and September 2003, there is a defective membrane panel. An electrical short can occur, causing the oven to activate without pressing any key pads. This could result in excessive heat, smoke or possibly a fire.
Samsung will notify its customers and repair the panel. In the meantime, consumers should unplug their microwave, if possible. If the consumer is unable to unplug the microwave, they should leave the microwave oven door ajar until the membrane panel is replaced. Consumers should never use the microwave oven for storage or leave any towels, paper, cloth or other products in the microwave after use. Owners may contact Samsung at 800-932-3837 or the National Highway Traffic Safety Administration’s Auto Safety Hotline at 888-327-4236. To search NHTSA’s database of recalls, visit www.nhtsa.dot.gov.

The following is extracted from the notice provided by Dometic to the NHTSA dated 8/26/06:
The potential defect is associated with cooling unit at the back of the refrigeration cabinet.
A fractional percentage of the potentially affected refrigerators have experienced a fatigue crack that may develop in the boiler tube in the area of the weld between the boiler tube and the heater pocket. A fatigue crack may release a sufficient amount of pressurized coolant solution into an area where an ignition source (gas flame) is present. Dometic's investigation has shown that a simulated release of cooling solution (refrigerant) in the area of the boiler, under certain conditions, could be ignited by the presence of an open flame. A boiler fatigue crack with the loss of cooling solution without ignition would result in a non-operational refrigerator that is not a safety issue. Under certain conditions, the released coolant could ignite and result in a fire. In order to have a fire, at a minimum, all of the following conditions must exist:
1. The refrigerator must be on and normally operating and gas burner must be lit;
2. 'There must be an oversized heating element in the refrigerator;
3. The boiler tube must develop a throughway fatigue crack of a
4. There must be a release of the cooling solution at a rate which will
allow the accumulation of the cooling solution at a concentration within its range of flammability; and
5. There must be ignition source (gas flame) present.
If any of these conditions are not present, a release of the cooling solution will not result in a fire.
In April of 1997 Dometic modified the design of the affected refrigerators by increasing the wattage of the heating element from 325 watts to 354 watts. All production of the affected units from April 1997 through May of 2003 utilized the 354 watt heating element. In May of 2003, in order to improve the operating life of the refrigerators, Dometic returned to the use of the 325 watt heating element which it continues to use today. It is now believed that the use of the higher wattage heater contributed to abnormal fatigue in the boiler tube.
The products in question are all refrigerators used in the original manufacture of recreation vehicles or as replacement equipment for recreation vehicles. The total population of refrigerators potentially containing the defect is 926,877. Dometic estimates a potential maximum incident rate of 0.01% related to boiler fatigue cracks that leak and may result in a fire. There have been no incidents of injury or death related to the affected population of Dometic refrigerators.
Dometic became aware of the occurrence of fires which may have involved their products and retained an independent engineering testing laboratory to fully evaluate and investigate any potential defect in their refrigerators which might result in a fire. A number of returned units were analyzed and microscopic fatigue cracks which could release coolant into the area of the burner were identified in the boiler tube metal in the area of the weld between the heater pocket and boiler tube. Tests simulating the cracks were conducted the week of August 18, 2006 and confirmed a possible cause of fire in the refrigerators under certain conditions. These test results prompted the preparation of this notice.
Dometic continues to gather information on the potential defect and will forward additional relevant information as it becomes available.
Dometic has not yet identified a proposed remedy for the potential defect. Dometic will continue a testing program designed to identify and evaluate possible remedies. This evaluation will take place both in the United States and in Sweden. Once a remedy has been identified, Dometic will initiate or participate in a remedy campaign initiated by the original equipment manufacturers and aftermarket suppliers who have purchased, sold, and distributed these products. A list of original equipment manufacturers and aftermarket suppliers to whom Dometic has sold the potentially defective refrigerators is being prepared and will be provided to the NHTSA upon its
