Sta-Rite MaxETherm lp400 not waking up this year

[patryanvb]

, Rodent built a next behind the control board (happened a few years ago to). I feel like I've repaired all of the wires
When it starts up I get a few codes on the display and then it goes dark and "check heater" light comes on
SFS light is lit on the back of the board

Any thoughts? double checked the wires to the stack flue sensor... no damage on those

If all wires check out and nothing chewed, sounds like the board is shot. Also did you check inside the control box to make sure no wires chewed? In fact check all wires in the heater and not just the ones by the board.
