I tried to replace the part thinking it would be easy. I ended up breaking the PCB suction regulator when I put the cover back on. This is definitely the correct part, but replacing it is a hassle as there is a fourth screw to remove underneath the circuit board (top). three externally accessible screws). Removing the top cover to remove the circuit board is not that easy as there are four locking points and only one is marked. Putting the top cover on is also tricky as the power button and suction cup have to be perfectly aligned on the board when it snaps into place, otherwise the board could be damaged! Edit 09/08/2020 I received a replacement board purchased from Sears and am back in business. As BUtraveller pointed out in their comment on Jim H's instructions, it's best to hold the handle upside down during assembly to properly align the suction door and power switch on the board.
