Hacking a Sunbeam heating pad???

I bought a Sunbeam model 721 heating pad at CTC. It has an "auto-off" feature, which must have been designed by Satan. It simply shuts the thing off after two hours. I can perhaps understand such a feature if it had an on-off switch or over-ride switch, but no, it just shuts off, so sleeping with the thing on LOW is pointless after is shuts off. If I can find one [another brand] without that feature, I'll buy I but I'm wondering it it is possible to hack the control and over-ride the 2-hour control. If anyone here knows about such controls and can point me in the right direction, please do.
Thank you.
I'm glad that I finally found the button.......

I wouldn't. That pad is made for warming when you're awake (or supposed to), not a sleeping electric blanket. Get the proper one; they have 10 hr-off cycle.
This therapeutic heating pad helps arthritic pain and everyday muscle aches fade away. Soothe and relieve discomfort with even, consistent heat to help treat the areas where aches occur. 3 settings provide a choice of intensity for personalized therapy. Includes a 2-hour auto-off and a convenient extra long power cord.

Respect the design. Its most likely designed that way for safety purposes, but if anyhting make sure you check the spec sheets on the other components if they are able to run at that capacity.

Yes, they would definitely disown me, like any hack I suppose.
I am not sure if it'll work on your model, but one of the comments on that page seemed to have an easy solution that doesn't involve opening it up and modifying the circuitry
Buy one of those cheap programmable timers that you plug into an outlet that will power a device off and on on a schedule. Set up the schedule to be every 115 minutes or so.
That way it keeps turning back on and resetting the 2 hour limit.

Thank you. I see the point. I'll give that a try. I think that I have such a timer somewhere in the house.

In case you are not aware, even at the medium temperature (around 138F) is enough to *cook* a steak given enough time. If you hack the auto-off and someone didn't know set it to medium or high and then sleep on it for the whole night, breakfast will be ready on the bed when he wake up.
