Fitment and ordering details

Catalog model references include FW3678. Confirm the full equipment model, serial number and door revision before ordering; model references do not establish fit for every production version.

Compare the 38-1/4 by 78-1/2-inch dimensions, three-sided layout and mounting profile with the removed gasket. Confirm the measurement method with the door documentation; do not substitute the clear opening size for the gasket size.

Service symptoms and checks

Torn corners, hardened seal sections, visible gaps or condensation along the door perimeter can indicate a seal problem. Inspect the gasket retainer, hinges and latch alignment as well. Replacing a gasket will not correct a sagging door or a damaged mounting channel.
