Could not find a Cannon site to contact online. If you have the original information when you purchased the blanket, it should at least have contact information. Also consider visiting a blanket store to ask how to find a new control.
I took the blanket to a thrift store and literally began searching for one with the correct configuration. Then, I plugged it in there to make sure it worked. Just make sure you tell someone what you are doing so they don't think you are taking their blanket.
The company who makes these blankets is actually www.biddefordblankets.com/
If you look on the bottom of the controller you should see this name. They also have a number 1-800-789-6441.
