Checked over pasta cooker unit, found running per staff request watched unit until it failed, found issue is with the flame roll lit switch being faulty. will order and return. 7/12/19 Removed failed rollout switch and replaced. Noticed door was being kept open. Spoke to manager he stated since propping door open they have not had an issue. They will close door and see if new rollout switch remedies issue. If problem reoccurs we will need to I investigate excessive heat in burner area.
