I have a Jandy LT 400N and the service light is flashing along with the temp sensor light, which is on solid. I replaced the temp sensor, and the lights did not turn off. I had the main breaker off for a couple of hours. Everything I tested seemed OK, however at test point 11 and 12, I have no voltage (should be 24v). The 150 and 135 limit switches have continuity, new temp sensor measures 11.3k ohms at 72 degrees (old sensor was way too low, so I do believe the new sensor was needed). Pressure switch tested OK. Question - is there anything you have to do to reset the circuitry? Any ideas why no voltage at 11 and 12? Thanks
