A little background: This is a home we are currently renting. I have never worked on a residential boiler until now, I typically only work on commercial/industrial. The radiators started to feel a little cooler than usual, but still heating the house. This is what i found:
Circ pump not running, open motor windings and coupler broken. Freed the bearing assembly up, oiled. The boiler is still firing with no pump running! So, I guess my questions are:
1. Is it typical for a resi boiler to have no flow switch?
2. No LWCO?
3. No high temp limit?
Now, I have seen a few resi boiler trainers, and they all had those safeties.
Thanks for any input in advance. Merry Christmas!
