Review on πŸ”₯ Honeywell Immersion Controller L8148A1017 by Christopher Buck

Fits perfectly. Attention: prepare for the possibility of replacing the well. Know your P/N.

I was fine with the idea of replacing it myself, except I wasn't sure how to properly remove and install the probe. So I called my HVAC relative and was glad I did. After more than 25 years, the thermal paste in the shaft was rock hard. He ended up breaking the well trying to pull out the old probe, and the water overflowed from the boiler. Luckily I had the original P/N boiler installation instructions, we got a new fountain and everything was fine after that. (Honeywell 123870A for my Burnham boiler. Your boiler may be different.)
