The trick really is getting the toaster apart. First the toaster I have is TFal Anvante mdl #572714.
Remove 5 screws in the bottom (you will need a torx Tamper screwdriver).
Remove 2 screws in the back (These have plastic covers that can be pried out with a sharp tool, I used a steak knife).
The two toast lift handles can be pried straight off.
The timer/stop button can also be pried off but these are stuck on pretty good so don't be afraid to pull/pry.
The side start handles/levers were the biggest problem for me. They didn't seem to want to come off. What I finally realized was that there was a little clip inside that had to be pushed open to allow the handle to release. these are only plastic and I ended up breaking both clips as they were a little brittle. once I got the start handles off I was able to pull the cover off part way.
Next there are two small cable connectors at the bottom front (4 slice toaster). that you can just pull straight out. Toaster cover will now come straight off.
Problem I found with my toaster. Left side not staying down. (Seems to be a trend with the left side)
BEFORE GOING FURTHER!! If you haven't disconnected your toaster do it now before going further. There are a lot of exposed live electrical parts.
I used a tooth brush to clean all of the toast dust. off the mechanical and electrical parts. You will see a white color electrical relay. This is what controls the magnetic coil that holds your handle down. Clean this lightly and careful not to break anything. I then used a vacuum to clean up as much crumb and dust as I could.
At this point you could just temporarily replace the cover, (No Screws) and make sure to connect the white cable at the bottom, plug in the toaster and test.
