What temps are you in? I had a frozen handle, which I got unfroze, but then had a frozen tank. All the time I was ready to start cutting out the underbelly. I am sure glad I didn't. In my case I ran enough heat it all unfroze. Could the metal handle rod that attaches to the cable assembly have possibly pulled out. RV dealers have either 2 or 3 different length handle/rods for black tanks. If your handle came off that assembly maybe you can get another one through the hole and attach it without opening up the bottom.
