This is a foamed in place door gasket. Since it is not cost effective to replace the door, you have to break the foam from in between the plastic door liner and the outer door with a putty knife and then pull out the door gasket and replace it with a new one. It's alot harder than it looks and takes alot of patience.
Also, make sure you only use the OEM belt, if the belt doesn't slip when it goes into spin with a full tub of water it will cause the splashing out the sides of the tub and may even cause the motor to trip out on overload.
Right part number, wrong video. You need to remove the slanted access panel between the washer and the dryer, then remove the front of the dryer, then the front bulkhead and the front of the blower housing. Everything is front serviceable, no need to pull the dryer away from the wall.
Why not just add a griddle as a bonus accessory to the refrigerator? Just take your frozen foods out of the freezer and cook them without taking them to the microwave or the range. Maybe that was where Whirlpool got the idea for the Polara range.
There is a "frost reduction kit" available for these bottom mount refrigerators that comes with a different evaporator motor fan blade, some felt seals for the evaporator panel, a new electronic control and a evaporator fan motor delay bimetal to aid in reducing the frost in these units. I will have to get back to you later with the part number because I don't remember it off the top of my head.
Does this unit have an add on drain pump or a gravity drain?
It looks like it is producing plenty of ice like it should be.
You have to remember, this is just an icemaker, the bin is there just to store the ice for a very short time, it is NOT a freezer. The melted ice has to drain somewhere, if the melted ice (water) is kept in the bin for too long, it will hinder the machine form making more ice. The unit has to be drained properly.
If you bought it used, chances are the previous owner might have removed the model and serial number sticker. On these models the sticker should be inside the ice maker bin either on the left or right side or on the ceiling.
