Should 'Heater Box" fit firmly 'INSIDE' or flush with the 'Air Duct Assemply"? Thanks.
Answer Hi Fred. Yes the heater box part # 3392537 does fit firmly into the Air duct assy. so the heat does not escape internally into the dryer cabinet ruining parts. Examine the opening of the air duct to see if there are bent in edges not allowing the can to fit into it. The Air Duct Assembly Item Number: 3387911. Thank You.
