Ok this may be kind of a random question. But I have scoured the internet trying to find an answer and I just cant. My girlfriend has a stomach problem and she uses a heating pad to help ease the pain and spasms at night. However, she often wakes up in the middle of the night because the heating pad reached a certain temperature and shut itself off(at least thats what I believe happens, or is it just on a timer?). Basically I am trying to stop this from happening. I was debating on getting a different thermostat, or something along those lines. Before I go tearing it apart I just wanted to see if anybody had done this, or had any knowledge on where to look for the info. Or whatever. Please help. Thanks.
