Hi, I bought the king size fleece electric blanket last year for my husband who has problems with his feet and needed it leaving on all night to sooth them, it was great, but when we started using it this winter it keeps switching itself to different settings. I always put it on full for 30 mins before going to bed then turn it down to number 2 for the rest of the night just so it keeps his feet warm. However I am finding that I am having to check it several times in the night because it either switches off or turns itself to full for 1 hour! Not sure what that is about but it's a bit worrying and I could really do without the deprivation of sleep. Any advise would be appreciated. Angela Wilde.
