Introduction

This guide provides instructions for the replacement of your Black and Decker TR1278B toaster circuit board.

Unplug the toaster before disassembly.
  • Unplug the toaster before disassembly.

  • Remove the carriage lever by pulling it away from the toaster.

Pulling requires a bit of force as the plastic lever is elastically squeezed over the metal tab and the tab as a little “step” that is visible from below the tab that needs to come out.

  • Unscrew all four 4mm screws on the bottom using a Phillip's head #2 (PH2) screwdriver.

Detach the bottom from the front cover using the plastic opening tool.

Watch out for opposite side (front end) 2 folding metal clamps that hold the front end and must be lifted up at least partially before the next step of lifting the whole cover.

Note also that opening with plastic tool here requires a bit of “force”. I came at it from the side with a thinner plastic tool to help (not unlike trying to remove a tight bike tire from a wheel rim)

Watch for two folding metal clamps holding the front end. They must be at least partially lifted up before the next step of lifting the cover. Note also that inserting the plastic tool requires some “force”. I came at it a bit more from the side with a thinner plastic tool (cafeteria plastic knife) to help lifting and insert the main plastic tool, not unlike trying to remove a tight tire from a bicycle wheel.
