IIRC there is a parameter setting for that B44 shutdown code. Set to “0” or deselect it to not have it in play. If your problem persists at the basement only, after you’ve checked magnets (if you do find the notorious non glued magnets) be sure to apply silicone to one edge of each slipped magnet, or a few drops of gorilla glue to three points after they’ve been situated properly AND tested.
Back to what KSNY was saying. Be sure the sequence of CG, DCL, DG signals are tight. Could be a bouncy pecker or the shorting bar is riding up and off the two contacts due to too much travel into the interlock box (or conversely too tight interlock and the pecker isn’t dropping right away). And again if I remember correctly, B44 shutdown can occur during the open cycle as well. As far as the signal sequence goes, my memory is different than KS, so maybe IDWT can chime in to clarify.
