L8418A Honeywell Aquastat

[robertjulius]

The aquastat on my boiler has been malfunctioning. Sometimes it works on its own, sometimes I have to help it along. I can get it to work if I press on the square metal piece attached to the small spring. It appears that the contacts on the electromagnetic relay on the aquastat do not line up properly. Is there any way to adjust the relay so that it works more reliably, possibly adjusting the length of the spring or bending in the frame of the relay a bit? It is an L8418A 1009 and I have been told that it has been replaced by an L8418A 1017. Thanks for any advice.

Nope, no adjustments can be made here. The problem is with the relay and it sounds like it's a few hrs. away from heading south. Replace the control.

Any idea who sells parts so I can rebuild the Honeywell L8148 A 1009? I replaced it with the L8148A 1017 and was hoping to repair this one to have as a back-up. I am trying to find a supplier of the electromagnetic relay,
Part Number 131630MZMS 17.

I doubt that you can repair it and even if you found a source for the relay it would probably cost more than the whole control. Sid Harvy's will take it and give you a core charge though.
