Replacement was easy; took about 15 minutes. All four burners work again. The new burner bowls sure do beat the old rusty, aluminum foil-covered ones. The only complaint I would have is that the terminal block wires are long enough to go to Mars and back; I had to roll up the excess wires and bread-tie them together and find a spot in the rear panel for it. It would be nice if two extra terninals came with the package so that the wires could be cut to length and then the terminals crimped on.
