Re: Electric Grill Thermostat/Energy Regulator

So I finally got the chance to wire in the part! Everything went smoothly and the rather unconventional-looking schematic (especially for Load A and B) got me there in the end. Thanks especially for your last post on the equivalents between the old and new energy regulator!

It’s very much appreciated and it means we have a grill in time for Christmas!

Re: Electric Grill Thermostat/Energy Regulator

I finally have my hands on the new regulator!

I now see what you mean by the “microswitch” comparison. In the old one, where the “line” blade connector enters the housing to form this flexible copper strip, it never ever makes contact with the “load” bimetallic strip assembly and contacts. The new one does move and is in contact whenever the dial is turned away from “off”.

Now, for the connections. The labelling of the blade connectors is confusing at best, as is the wiring diagram/schematic and I’m not unfamiliar with schematics either. Only the signal contact is obvious to me. By the push to make/break hybrid nature of it, I cannot work out continuities between contacts unless I can supply electricity to heat the damn bimetallic strip in the first place! A bit of a catch-22.

For what it’s worth, here’s the wiring diagrams in one PDF: http://www.diamond-h-controls.com/image … ators1.pdf

I have one of the 43ER series energy regulators.

Re: Electric Grill Thermostat/Energy Regulator

This is the thing, the cam has a copper contact resting on it and this copper bar moves closer or furtherto the bimetallic strip and heater above it (as you move the dial). But at no point does the strip (which is connected to line) ever come next or near to connecting to the bar above it. In other words, there’s no way for electricity to flow from the bar resting on the cam to the “Load A” assembly above. There is only continuity between the “Line” and “Load A” terminals when I bend the bimetallic strip with my finger to force it to make contact with the copper strip resting on the cam.

Thanks for the description anyway! It seems strange that the part does the opposite of what you say, in that it will only switch on when the bimetallic strip makes contact with the strip resting on the cam. What you said is how I figured energy regulators in general should work, but there you go.

I’m figuring one of the moveable parts has fallen out or somesuch so either way, the part is a write-off. Is that 43ER101C1 part a swap in replacement, ignoring the changed names for the contacts, for the 33ER3MHT like what the online parts shops tell me? I may email Diamond H too, assuming they still have their factory in Coventry…

Thanks again dave.

Re: Electric Grill Thermostat/Energy Regulator

Ah that’s great to know, will save me the expense of buying and paying for delivery on a useless part.

Aside from the usual wiring precautions and safety measures, is there anything in particular that needs to be done with a new thermostat to get it working? i.e. calibration, adjustment etc.

The internet tells me :rolls: that 43ER101C1 is the swap-in replacement but of course it’s not a great source of information. Still, more than Diamond H themselves offer in details…

Would you have any idea on what’s gone wrong with the old part btw? It’s as if I’m missing out on something very obvious.
