A user may need to replace a Sunbeam electric blanket control when the blanket stops heating correctly and troubleshooting efforts fail to restore heat. A user should contact Sunbeam directly if he needs replacement controls for the electric blanket.
If an electric blanket doesn't heat up, the user should unplug the power cord from the wall outlet, then plug it back in. The controls should stop blinking and reset. If this doesn't occur, the unit needs repair or replacement. If only one side of a dual-control electric blanket heats up, the user should plug it directly into the wall and turn it to the highest level for 20 minutes; if it still doesn't work, the user should unplug it immediately and contact Sunbeam for repair or replacement.
