Anyone know why this model is so hard to find
Because it is Canadian and specific to Sears Canada
whom is out of business. Sears Canada never put any of their product information online.
If you contact Frigidaire Canada
they can look up any part numbers you need as they made that particular unit for Sears. Ask for the part number. You can then order it from a local parts supplier using that number.
