Product review (5 stars): primarily because I didn't leave the door open for a day or two to dry out as recommended - my bad
My front loading Frigidaire washer developed mold after several years of use, primarily because I didn't leave the door open for a day or two to dry out as recommended - my bad. I have an excellent mold killer developed after Katrina called MoldStat that can penetrate nearly anything (bleach can't kill mold in wood), but even that stuff could not get mold out of the rubber gasket. Last week after finding another buildup of mold due to debris clogging the drain ports in the gasket, I decided to replace it. I used to be an engineer, very mechanically inclined, but this job nearly got the best of me!

Big Mistake: I tried to replace the gasket without taking the top and front panels off after reading here that it could be done - it was a nightmare trying to get the lip of the new gasket over the metal flange inside the washer. After fighting it for an hour, I gave up, exhausted, with bloody hands and bruises.

My suggestions from experience:

1. After you tilt the washer to get to the bottom screws, leave it up on a couple scraps of 2 x 4's, makes everything easier to get to.

2. Remove the top and front panels! Gives you much better access to the gasket flange. Have a few scraps of lumber ready for when you remove the front panel - there is an electrical connector that will prevent you from setting the front panel on the ground with it tilted - carefully snip the tip of the wire tie holding the wire harness to the back of the front panel -it sticks out through the flange of the panel (do not attempt to snip it where it wraps around the wires!), then set the panel off to the side on the lumber.

3. Do not use dishwasher soap to lube the flange or gasket - made it so slippery I couldn't get a good grip on anything. I rinsed off the soap, dried out the gasket, then sprayed a garage door lube inside the gasket, let it dry overnight - provided lube inside the gasket without being slippery to the hands. Any sort of spray-on dry lubricant should work.

4. Reinstalling the inner spring that holds the gasket to the inner flange was beyond miserable - the two spacers that came with the gasket were too large, couldn't jam them in place to hold the spring at 12:00. Instead, I got some scrap wood ~ 3/8" thick, and used a C-clamp to hold the first piece of wood and spring in place at 12:00. Worked my way down both sides using additional pieces of wood and clamps until I got the spring to 7:00 and 2:00, at which point the clamps were preventing the spring from stretching any further, so I removed all the blocks/clamps except for the two at 7:00 and 2:00, then got the rest of the spring in place - was a huge struggle though - had to use every ounce of strength I had to stretch that sucker far enough and roll it over the flange. For some reason at this point the spacers actually fit, used them to slowly get the last bit of the spring installed a few inches at a time.

5. While it's apart, take the time to thoroughly clean the inside of the washer where the detergent/bleach dispenser resides, use cleaner of choice and an old toothbrush - found mold in there too - then reassemble/reinstall the panels. Use a wire tie on the right side wire harness you clipped off in step #2 to hold it in place and prevent it from rubbing on the panel.

BTW, this Frigidaire gasket ($81) is identical to another one sold here under the Kenmore brand for $71, which is the one I bought - part number is the same - "Kenmore Sears Washer Front Load Door Rubber seal gasket 134515300-KE". Gave it 5 stars because the product is fine, although the instructions leave a lot to be desired.
