Wow, I have no idea how I confused this.
Reading it this morning it is clear you are talking about the AC portion of your heater. Old age is sneaking up on me.
The black AC switch is exposed to the elements and can be corroded.
If that is the case, it can be repaired or if it is actually "on" (voltage at the element) you can put another switch in the circuit (at the plug for instance) to turn it off.
If it has been on when winterized, Windrider is quite correct, your heating element will need to be replaced. Propane is your only option until you get the AC portion repaired or replaced.
