Needle Broke/Not Serging Properly
I haven't tried this to make sure, but my best guess (5 months late...) is that you are serging with three threads and that when you replaced the broken needle, you mounted the needle on the left mount. If you are serging with three threads the needle needs to be on the right.
The fourth thread goes through the needle on the left and provides what looks like a straight stitch. The lower looper catches the fourth thread underneath the fabric, but the upper looper does not reach it on the top side. If you use the left needle, but not the right one, I imagine you would only get a straight stitch.
Another guess is that you replaced the broken needle with a standard sized sewing machine needle. The 5280E uses a shorter needle. (DC x 1F). If the needle is too long, it may not rise high enough to loop with the upper looper properly. It probably still catches the lower looper and leaves you with a straight stitch.
I hope you solved your problem a long time ago. If not, I hope this helps.
