I just came across this site when surfing the web for help. I have been rebuilding a smoker from an OLD refrigerator which I have used several times in the past. I have a brinkman add on electric element and now I am wanting to wire up a PID temperature controller. I have bought a Mypin TA4 RNR controller and a SSR 25 DA. I have them mounted into a box on top the ole frig nice and neat. I have cut an extension cord female end off and connected the white and black wires onto at 1 and 2 screws. I have an old thermocouple wired up to the 7 negative and the 8 positive screws with the positive and negative sides of the thermocouple. I then have a wire from the 3 screw on controller to the 3 on the SSR and a wire on the controller 4 screw to the 4 on the SSR. I then have the cord from the electric heating element wired to the SSR with the black wire to the 1 screw and the white wire to the number 2 screw. Just so folks know I am an electrical illiterate and picked this up form as much as I could tell from the controller instructions. The controller does power up but the element does not heat when I put the set value at 200. The top temperature shows UUUUUUU across it. I did also fumble my way through the instructions to change the C to F. Can anyone tell me what is wrong or if I even have what I need to do what I want to? I'm basically switching the element off and on so that it maintains my temperature.
