Blown Fuse in my St Croix Hastings pellet stove

[Jim Kassal]

My basement went cold and upon investigation, I found my pellet stove to be off. Its a Hastings by St Croix. It acted like it was unplugged but it was not. Upon checking the fuse, it was blown. I replaced it but still nothing. It did not blow again, but it still acts like there's no power. I checked for 120 volts on both sided of the new fuse and it is there. But there's no response to pressing the ON button to start it up. I replaced the control board several years ago. Should I assume it is bad again?

Any suggestions?

I don't see a wiring diagram, but check the high limit switch and try to reset it

I see reference to a high limit switch in the manual but don't know where to look for it. And, if that high limit switch tripped, there would be indicator lights blinking. This stove is electrically dead.

Part 5 - I don't have a wiring diagram, but I have seen these switches wired into the controls.
Edit - If you measured 120V to the neutral on the board (not ground) before and after the fuse, and it's not the high limit, then perhaps the power supply part of the board is bad ie the DC might not be there.
