both of my ovens and 2 of the burners on my kitchen range did not heat up.

Turned off the power at the fuse box. Removed the oven elements by removing the screws and pulling off the electrical connectors. (Checked that the connectors and wires were in good condition and bent the wires so the connectors wouldn't pull back behind the rear panel.) Attached the connectors to the new oven element and screwed the cover plate back into place. Tested element. Repeated process for upper oven. For stove removed defective terminal block and checked that the wires were still in good condition. Twisted the new wires to the old ones added a bit of solder and the wire caps and then slid the shrink wrap (included with the block) over the connection and shrank it. Screwed the terminal block in place and tested. Repeated for the second burner. Works as good as new!
