Our fancy DeLonghi EO1258 convection oven (i.e. glorified toaster) suddenly stopped working. Nothing worked; it appeared as though the unit had no power. If this has happened to you, it may be that the thermal fuse inside the toaster has simply blown. It seems to be a common symptom, likely planned obsolescence to keep DeLonghi's service center in business. Learn here how to repair it yourself with a $1.49 part and 20 minutes.

WARNING: Never open the toaster while it is plugged in or has power! Serious injury or death could result! This howto is for informational purposes only. By following any of the procedure outlined here, you implicitly agree to remove any liability from this web site or the author(s). Only professionals should attempt electronic repair. There. All set.

Step	Description	Photo
1.	First, you must remove the grey plastic side piece into which the power cord runs. You need to remove the two torx screws pointed to by the red arrows. These are special "safety/tamper-proof" torx s screws with a peg in the center. I didn't have a special driver, so I simply drilled the pegs out and used a normal T20 torx driver to remove the screws. Underneath the unit is a single phillips screw holding the side piece in. Remove. These three screws (2 torx, 1 phillips) are the only screws you need to remove.
2.	Pop the side piece off. You should be looking at something similar to the picture. The thermal fuse is within the plastic sheath that's beneath the metal bracket pointed to by the red arrow.
3.	Loosen the nut holding the fuse beneath the plastic sheath.
4.	Disconnect the black lead from the terminal pointed to by the red arrow. Using needle nose pliers, pull on the plastic sheath to remove it from the housing (pointed to by the green arrow).
5.	Use pliers and a flat blade screwdriver to separate the black wire from the leads of the fuse. Save the small metal crimp piece.
6.	The culprit. This is a SF169E thermal fuse. Apprently its 172C rating is just too sensitive. You want to remove this fuse using step 5.
7.	Crimp the new fuse (NTE 8167) back inline with the black wires. Reverse deinstallation procedure. Put plastic sheath back. Place fuse back under metal carrier and tighten bolt. Reconnect black lead. Reinstall side piece. Done! If this procedured helped you, please consider helping a starving grad student out with a $2 donation (link at top of this page). Thanks!
