I hope someone can help me.
I have been getting my Effective Heat furnace ready to fire up for the first time and am having some problems.
When I increase the temperature on the Watlow 981 it is lighting up the Din-a-mite in short pulses, and that is causing the transformer to make almost a spitting sound. At the start the elements are warmed just a little (a couple of degrees) and then no more temperature rise. If I put a meter across a line of elements I canít see any voltage.
To me, this looks like a controller problem. Its almost as if the controller is not holding the Din-a-mite closed long enough to allow heating to occur.
I have listed me Watlow 981 settings in the hope that someone that understands these things can advise.

I would call the help line at watlow before I took random advice here. Since they built both your watlow controller and the SCR it makes far more sense. Try to get Larry.

Call Brent.
That would qualify as random advice.

Call Brent.
That would qualify as random advice with some stuff dripping from it. .

I would guess that the 981 settings would be the same for any of Brent's or Steve's furnaces?
I called Watlow Australia and they told me they where really a service center - - if I have to I'll try Watlow US.
I would try to talk to Brent - but to put not to fine a point on it - he ripped me off. I was stupid enough to pay him the money before the furnace was unpacked and he was gone. I sent him a message via facebook but he didn't reply.
The furnace he sold me was missing the cooling system, the thermocouple, more than half the wiring wasn't done, and I'd say that a few of the elements look like there preloved.
A little help would be very welcome.

I was dead serious about calling watlow. It sounds to me more like something in the SCR and it has a power series if I'm not mistaken. If it has a din o mite I know zip about them. Steve and I were sharing a private Joke, and yes I know about the stuff Brent failed to do. It gives us all bad reputations by association. Watlow is the single best place to start right now. I'm not trying to put you off. It's going to be one of those middle of the night calls you are going to have to make.

If you want, you could call tim bassett and compare settings but I really am suspicious of the SCR.

Any time I have had to call Watlow they have been awesome in helping and diagnosing what was needed.

Looks like your limits are all over the place. Call me with a volt meter by your furnace and I will help. Cheyenne 208.867.9517

Hi Mark, Just came across your post. I had a similar problem with the xformer surging... and finally having to buy a new SCR Controller. I've checked your settings with mine and one big difference... is the Operations rA1 setting...mines at 0.19. Very busy at present but if you still having problems please give me your phone number and will call to compare settings. I'm just over the ditch in NZ. Cheers Ron

Thanks to the help of Steve Stadelman and a few others, I think the problem is solved. Basically Brent didn't install a current transformer on the power supply - thanks again Brent!
