well I JUST went through this same thing, but with BIAB control panel. I had another temp probe sent to me and that did not fix it. You have to do a resistance check between the pins at the temp probe. You should get resistance between pins 1 and 2; 3 and 2; and nothing between 1 and 3. I'm not at the house so the pin numbers my be off, but what you are trying to find out is what pins are + and which is -. you should have two positive and one negative. Once you figure that out, you will need to see how the wires on the plug match to the pins. I had to pull the sheathing back enough to see what color wire plugged into what pin. Plug your wire going to from your temp probe to your control box and test the two red and one white wire at PID, you must disconnect the wires for the test. The wires SHOULD match the pins on the temp prob if not the wires do not match, all you will have to do is re-arrange the wires on the pid to match the temp probe. tOr, you can unsolder the connectors and re-solder them in the correct layout. I apologize it that is confusing.
