Something is definitely wrong then... The only time the stoker/primary fan should cut out during a call for heat is at high limit. When the fan and stoker do run, does it look normal? Maybe your triple aquastat is having issues.linkman2448 wrote: ↑Tue. Apr. 02, 2019 9:04 amMy KA-6 has separate motors as well. The secondary keeps running but the primary keeps shutting off when the boiler is cycling. I thought if I had a motor issue, it would trip out and need to be reset but it just stops running even though the thermostat is calling for heat.

I had issues with this batch of coal burning this year and the only way I could get it to burn better was slowing the feed down and decreasing the air from the blower. I also added doubled the amount of pins in the timer so that hold fire timer would turn on every ten minutes instead of 30 earlier this year when we had a warm spell in order to keep the fire lit. I haven't checked control settings with a multimeter yet. Can you tell me what readings I should be looking for?
What timer do you have? Is it the Intermatic 30 minute timer or a Tork timer?
I have my hold fire timer set to run 12 minutes every thirty minutes in this way;
4 minutes at zero time
2 minutes at seven minutes
4 minutes at 15 minutes
2 minutes at 22 minutes
I still have outfires when the weather gets warmer at times without a heat call and I need to buy more pins and add more pins.to the 2 minute settings.
