Just make sure the wires attached are to the right terminals on those switches.
First thing I would assure is that there is DC voltage on the PID terminals 7&8. If no DC voltage there, the PID is not in RUN mode or is defective.
Then see if DC is at the SSTs on terminals 3&4. If not, one of the two safety switches isn't right.
If DC is at 3&4 but there is no AC to the coils, then one of the SSRS is bad or the coils are not a continuous circuit (bad connection or burned out).
You can assure the coils are right by 1) unplugging the power cord, 2) disconnecting the coils at the SSR terminals (#1? by the images) and reading the resistance. If it is correct, then the coils are fine. If the circuit is open, there is a connection or coil problem.
All this is assuming that the PID is programed right and is in the RUN mode with the set point at something like 1000°.
