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 It is an L8418A 1009 and I have been told that it has been replaced by an L8418A 1017.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.
