Only 1 side of my sunbeam H85KQ mattress pad will heat. How can I troubleshoot for a fix?
If your model has two heat control thermostats, its possible that there is a fault with one of the thermostats.
Worse would be that the electric cable that runs thru the blanket is broken.
You would need specialised test equipment to find where the break is, unless you can actually feel the cable is split when you run it through your fingers.
Normally, if the electric cable is broken, the blanket is not servicable, because you would have to cut into the cover material to try find the break and replacing the cable is impossible outside of the factory. Read More At : SG7621SP Grill...
