moffat is an electrolux line and if you call a serviceforce agent they will be able to supply part.Far cheaper sometimes from online suppliers.just email them with product and serial numbers and they will contact you with availability and price.you need to remove the back panel inside the oven cavity and also remove the back panel by pulling the oven out.remove the fan blade (clockwise) then from back remove fan motor.very straight forward/simple job
