in Oil Heating

Are you saying the boiler is hot for Domestic Hot Water, but the heat will not circulate thru the radiators? Then we know the oil burner part is working.
There could be several reasons for that type of failure. The most common one is Air in the Radiators. It could also be a defective circulator pump. If you have an electric meter to test for 120 VAC you can see it the circulator pump is getting power. There are several other things but lets start with those two.
Can you post any pictures of your boiler from far enough back to see all the connecting pipes from floor to ceiling from at least 2 different sides.Edward Young Retired
After you make that expensive repair and you still have the same problem, What will you check next?

It appears to not respond to the thermo. I call for heat but it does not fire. If I run the water it will ignite for water. The boiler is not igniting so not heating up. But the circulator pump is on.0

What has changed? Are the batteries low in the thermostat? (assuming it has batteries)

that sounds like there is air in the pipes that go to the radiators. What radiators do you have? Baseboard with the copper pipe and aluminum fin? Cast iron baseboard? Cast iron old fashion standing radiators, convectors in the wall? Depends on what type radiator you have to know how to get the air out.
Also what does the boiler water temperature gauge and the boiler pressure gauge point to? (usually 2 pointers on the same gauge)Edward Young Retired

Bad pump? Circulator? Prevent boiler from starting?0

Is the coupling intact in the circulator?
If the circulator isn't moving water the boiler will heat up to the high limit on the aquastat then shut off because the circulator isn't moving water out of the boiler to take the heat away. If it is air bound the same thing will happen.0 -

Yes the circulator coupler is intact. The boiler has not ignited. Ice cold. Will only fire for water0
-
Is there any way to start boiler bypass relays. Absolutely no heat at this time0
-
Batteries in thermo changed out. No diff0

Boiler temperature only drops with hot water use...
Or, if the boiler is going cold like the tridicator says (110° and Lo set to 150°), and the circulator is definitely running, then it's a bad aquastat. And they make better ones than the L8124A.1 -
The tridicator might be in an air pocket in the boiler so it isn't seeing the actual boiler temp.
It looks like there is a flow check on the outlet so if the circulator is air bound and not pumping any water no heat is leaving the boiler.
If you have a steel compression tank you need to manage that occasionally too.0
