The high limits could be fine, or not. Check continuity across them with wires removed, and try the reset Hermann mentioned.
I don't recall whether you said the red steam boiler light is coming on or not; if so, check voltage at the boiler first and that will clear the high limit and p-stat if you're getting voltage. If not, check input voltage to the p-stat, and output on the steam side to see if there's voltage leaving the p-stat to the steam boiler. If not, as a temporary fix/test, switch the output side to the steam boiler and to the brew boiler; if the steam boiler heats, the p-stat is dead or stuck. DON'T leave the wires switched! Try screwing the pressure up and down a bit to see if the p-stat comes unstuck (and order a new one). If you have voltage to the steam boiler in the first test above, check resistance across the steam boiler terminals with wires removed; 13-17 ohms (or a little lower) is fine. Hope that helps; you'll probably get it sorted rather quickly I imagine. I have had a Jaeger last 4 years, and one last 90 days. It's hit or miss. I think Hermann had similar results. They don't last forever. I have another factory one in place now, and it occasionally sticks and sends steam to 1.8bar and blows the over pressure valve on the steam boiler. THat's always exciting. Nothing is perfect, at least that I know of. :) best, bmc Sent from my apple IIe > On Jun 12, 2016, at 06:35, James Lodge <[email protected]> wrote: > > My high limit switch looks the same so that's probably not it.
