Grew up with a permanently installed version of that machine.
Was a model-year later, in that momma's had a "hot" and "cool" dry selector.
Hers was a model "up" with two lights over those elongated pushbuttons and four neon indicator lights for temeperature behind script writing saying:
"COOL"
"NORMAL"
"SANI" and
(time) "DELAY"
The sequences were W-R-R-W-R-R-Dry for the "Normal" wash. Light wash was R-W-R-R-Dry (which was the cycle of choice in our home; everything was pre-washed to within an inch of its life).
The bad thing about the fan is that it sucked out. Rotted all the cabinetry. If it blew in, it would have rusted and rotted all the wiring in the front foor wiring "chase". (See panel #39971 for the air vents at the bottom of the door).
The only air vent to the outside from the front of the machine was surrounding the door latch slot which was I'd say was 4 inches(102mm), or maybe slightly less in width.
Mother toggle's model had the loudest blower fan. Had to wedge a thin board between it and the body of machine (procelain tub) to keep vibrations tolerable.
Have fun with it its a powerhouse. Be careful with acids (coffee, lemon juice, vinegar, wine tomato sauce/juice) they will dissolve the porcelain.
