my (older style) oct 20 motor has died on me so the fan no longer turns. the heating still works but of course doesnt get distributed anymore around the incubator. the motor in the unit is a heidolph 240v (118.08.00024) ive searched and searched online but cant find one? do any of you techy type people know of another small motor i could use to drive the fan, that will fit in the casing of the older octogan 20's??
