TROUBLESHOOTING THE IGNITOR SYSTEM

Refer to the illustration below while you read the following troubleshooting information.

Ignitor Does Not Glow

1.Disconnect or remove the ignitor and mea- sure its resistance. Cold resistance should be between 50 and 150 Ohms. (The value of the resistance is not important as long as the ignitor is not open or shorted).

2.Check the internal fuses, switches, and 120 VAC power supply.

3.If power is working:

a)Disconnect the oven power and re- move wires at “B” and “C”.

1.Check continuity between wire “B” and terminal “C”. If continuity is present, go to Step 4.

b)If continuity is NOT present, remove wire at “D” and probe terminals “D” and “C” for continuity. If NO continu- ity, replace the bimetal valve.

c)If continuity is present at “D” and “C”, probe wires “B” and “D”. If NO continu- ity, replace the ignitor.

4.Check for 120 VAC at the following loca- tions, and the relay(s) on the Electronic Oven Control you are servicing. Also re- fer to the wiring diagrams on the next page.

Diagram A—Bake:With the EOC programmed for the Bake mode, you should obtain a read- ing of 120 VAC between P3-1and P2-4, and between P3-4and P2-1.

Diagram A—Broil:With the EOC programmed for the Broil mode, you should obtain a read- ing of 120 VAC between P3-2and P2-1, and between P3-1and P2-2.

Diagram B—Bake:With the EOC programmed for the Bake mode, you should obtain a read- ing of 120 VAC between P2-4and Neutral.

Diagram B—Broil:With the EOC programmed for the Broil mode, you should obtain a read- ing of 120 VAC between P2-1and Neutral.

Ignitor Glows With No Ignition

1.Check that gas is turned on to the range.

2.Turn the power on and set the thermostat to 350˚F.

3.Check the ampere draw at the bimetal valve.

a)Using a wraparound ammeter, test one leg for ampere draw at "D" or "C".

1.NORTON (flat) Ignitor - 3.2 to 3.6 amps.

2.CARBORUNDUM (round) Ignitor-

2.5to 3.0 amps.

If the ampere draw is NOT within the proper range, replace the ignitor.

b)If the correct ampere draw is present, replace the valve.

For safety purposes, when measuring the current flow through the ignitor circuit, shut off the main, or the oven gas shut-off valve.

NOTE: A simple circuit is shown. The actual circuit may include fuses, clock, selector switch, or other items.
