I got a ladder to reach the vent, but it does not appear to have a mechanism to open any further. In looking in the microwave manual, it only references that the installer should make sure the vent flap moves freely. To me this means the outside vent does not open, but there is a flap that should open automatically in the unit. Can others with the Whirlpool microwave in the 36ckts tell me how their fan operates? Thank you.
I think I can offer some advice on the subject. First microwaves usually are furnished with a "baffle" that is adjusted before its lifted into position. Most all units have it because in "Position A" it's set to recirc the vent air through a washable filter and back to the room. In "Position B" all air is directed through the back and upwards, connected to a duct and directed outside. This is for homes as well as RV's. Secondly I had a RV that had an additional flap or door within the vent hood. It used a sheet metal handle to remove a pin which locked the door closed. When slid out the handle would move to unlock a sheet metal flap to the outside. There another door with two latches locked a rectangular door on the outside as yours. That door would open at least 2" on a hinge setup. So you can see at least three blocks to the air flow. Best test, you should feed good air flow outside when its running. Leave removing the M/W to the dealer if it must be dropped to adjust the baffle. Its under warranty.
