Ordered burner control unit. When unit arrived turned off power to stove at circuit breaker box, went to stove attempted to turn on stove light and a burner to confirm power is off. Pulled stove from wall, removed back panel to gain access to burner control units. Placed new unit next to old one to assure correctness, removed control knob, removed the two mounting screws which secured unit from front panel, removed old unit, placed both units side by side and removed one wire at a time and placed on the new unit. This assured correct placement of each wire. Installed new unit with two mounting screws and knob. Replaced the back panel, cleaned floor underneath stove, pushed stove back into place, turned circuit breaker back on then turned new unit on. New control unit worked fine.
