Product review (4 stars): It looks like the correct spring for the LFX28979 is MHY62044103
Almost fits LFX28979ST. I had to bend the legs to make them effectively shorter, and they didn't break. I'll take that. If you're up for this, wear safety glasses!

I'll try that next time...

It arrived very fast, but as usual package was 100 times bigger than necessary.
