I've had a Sunbeam heated mattress pad with dual digital controllers for several years. I've recently noticed that it no longer gets as hot as it used to. In my pea brain I assume that if the element gets warm then the output problem is with the controller.
If that is correct is there anything I can do as an amateur to fix this? I noticed that one of the controller dials is stiffer to rotate so I wonder if over the years if dust etc can get into the controllers and interfere with the contacts (getting it to the higher heat levels) and maybe some isopropyl alcohol or canned air might resolve.
Thanks in advance....
