Sunbeam electric blanket showing E on the controle box

SOURCE: My Sunbeam electric blanket controls

Same problem, but now it is ok.  I emailed Sunbeam and was told that if my blanket was not plugged directly into a wall outlet it was not getting enough power and I needed to plug it into a wall outlet taking these steps:
1) Unplug from the surge protector/extension cord 2) Unplug from the blanket 3) Plug back into the blanket 4) Plug into a wall outlet

Call the manufacturer. They will often do repair for free.

Did you get helped last year? If so please ignore. Otherwise....

Hi. You can locate a Sunbeam Service Centre via http://www.sunbeam.com.au/Pages/Support/Repairers.aspx

You're looking at $69,95 recommended retail.

BTW have you checked that it's not the blanket? Swap the controls over, if the problem follows the control it's the control. If the problem stays on the same side of the blanket, it's the blanket.

Also note Sunbeam has a 3 year warranty on electric blankets. If Date Of Purchase is less than 3 years ago call 1800025059 option 1 to speak to their Customer Service,
