HELP! from sparkies please
On 30/7/2018 I bought a new Robertshaw thermostat model CS9610N from Reece for my Hardie Dux 315L single thermostat model which runs on controlled 1. Paid $51 which is a lot I now find.
Yesterday water is cool again.
I checked element resistance at about 11.5 Ohms and to earth about 10Mega Ohms.
So I assume the element is OK.
I removed the thermostat and I have continuity at room temperature between terminals 3 ( neutral) and 4( element) but no continuity between 1(active) and 2 (element). The excess temperature button had not popped.
Am I correct in assuming that at room temperature there should be continuity?
I adjusted the cutout temp and tested but no difference, and pressed the disc in but no difference.
This is expected but I think there should be continuity at room temperature as the device is just mechanical thing that should not depend on power , as it only depends on the disc distorting to open the contacts at the set temp, in my case 60C.
Urgent help needed as SWMBO is not impressed.

I am wondering if the thermostat has failed or no ripple for the last two nights.
BTW, I have the thermostat at my computer and just manually tripped the over temp button by pressing on the disc. It disconnects the neutral side.
