Just as your video showed. Where did the solder go? For me, it wasn't the circulator, it was the oil burner. But thank you Brian, we have heat again. Yay!
Also having trouble with my Aquastat and will work thru this fix if it is the problem (Intermittent firing.) NOTE: I also had this problem with the kitchen stove. It originates from what I understand from the manufacture of the board. The solder joints are "cold" and do not bond correctly and when the power heats up the joint because of high resistance the remaining solder just flows away from the joint. Boom! no connection. Fixed the stove 2 years ago and is still working. I guess this will be the next project. Thanks so much for the schooling, I LOVE YT providers who do this kind of stuff!
The brushes on the burner motor could also be going bad. Check the output of the aquastat for power with a multimeter. If there is no power, the problem is in the aquastat. If there is power the burner motor is the problem. Good luck on your repair.
Excellent. I had the same problem with the circulator working intermittently. I followed your clip and had ONE solder that simply disappeared. I resoldered it and now works beautiful! Honeywell needs to do better quality control in their manufacturing factories! Thank you very much!👍
The soldering and contacts sanded worked for a few days. But I had to install a new aquastat. no problem one hour install turned on everything fired up except the furnace and that’s because I didn’t put the jumper on for the 24 V on the Honeywell J1009. I believe that’s the last four digits. I couldn’t of done it without you. Thank you.
Also, in another version of this Aquastat, there is a 6 pin connector for damper control. The solder joints on this connector also frequently go bad and can be repaired.
Thank you sir. I am having same problem where pump won't run, but boiler is heating. The relay is moving but is making a buzzing sound. I am going to replace or repair this myself after watching this, I thought there was water under pressure where the thermostat slides into the pipe.
Great Job Brian , I'm sure many people run into this common problem... minor suggestion and if possible use a desolder wick to pull all old solder off board ,clean with alcohol , and when resoldering if you access to solder flux pen apply 1st and you'll end up with factory type strong solder. In a pintch I'd do exactly as you did, once more GREAT JOB BRIAN !! my 2 cents : Mass.🛠 plumber
