I have a Amana 80% Commando GUIC140_50. The blower needed replacing, and the service person replaced it with a 3 speed DL1076. The previous blower was 4 speed. Are these the same -are they pushing the same amount of air?
My temp rise is 60F when the fan speed is on high - the specification sheet for this furnace shows less than 49F temp rise on high.
