Spark Igniter Switches and Harness Assembly

The ignitor switches are installed on top of the 4 gas valves for the range top. These switches control the electronic ignition. To replace the switch assembly the top of the range must be removed to gain access.

This was made more difficult by the fact that the screws that hold the burners to the range top were rusted and had to be drilled out so the the burners could be released from the top.

1. Disconnect the power to the range.
2. Open the top oven door.
3. Remove 2 - 1/4" sheet metal screws at the front corners of the range top assy. Remove the Burner knobs and the two Phillps screws that holds the gas valve assembly to the range top.
4. With a drill, remove the tops of the screws to release the burners from the range top. If the screws are in good condition and just unscrew them and the upper burners from the Orifice Holders. (I had to replace the orifice holders because the screws were stuck in them due to rust).
5. When the burners are free, lift the range top at the front and remove it from the range. Disconnect the ignitor wires from the ignitors on each holder.
6. To replace the Orifice Holders, disconnect the gas supply pipes from each holder by loosening the compression nut at the holder using an adjustable wrench. Secure the Orifice Holders when loosening the fittings, BE CAREFUL not to damage the aluminum gas supply pipes.
7. Note that there are 3 different Holders, be sure to use the holder that matches the specific location.
8. For LP gas fueled ranges ONLY, remove the small gas jets from the old holders and install them in place of the parts supplied with the new orifice holders. The new parts contain NATURAL GAS jets which are not compatible with LP gas. Each Different Orifice Holder uses a specific orifice or jet, make certain that the orifice matches the orifice holder. Check for leaks at the gas connections using soapy water.
9. Carefully raise the old ignitor switches (4) off the shafts of the gas valves. Note the top and bottom configuration of the switches
10. Carefully release the wires that come from the rear of the range from the rearmost switch. Press a suitable pin or other suitable tool in a the hole, beside the wire, just enough to release the wire. (Look at the NEW switch assemble to see how this works). Remove the wires from the NEW switch first to see how it is done. Repeat the process on the old switches. (you will re-use the wires that come up from the rear of the range.
11. Install the new switch assembly over the four (4) burner gas valves, take care to align the "D" shaped shafts with the holes in each valve.
12. Insert the wires in the two connections on the rearmost switch. CAUTION!!! Be sure to install the wires so that the color codes agree with the wires on the new switch assembly. Black to black and gray to gray.
13. Install the 4 clear plastic "shields" over the shafts and against the top of each switch.
14. Re-connect the ignitor wires to the burners and Re-Install the range top, in the reverse order of dis-assembly.

I must admit that I did not do this. A neighbor who has electical experience did the job.

The screws that hold the ignitors were too corroded to reuse. It required drilling new holes and taping threads. If self-taping screws were included it would be easier to replace.

The switch was much easier to replace with flare nut wrenches.
