My DCS-RG305 Range broiler was not working, ignitor was not glowing. I checked the voltage on the ignitor leads (it was 118v) so I assumed it was the ignitor. Picked up a replacement at local appliance part store. I installed it and tested it without gas and it glowed red for 5 seconds. Turned it off, turned on gas, and it lit up again, gas came on and ignited. Then I heard a loud noise and turned it all off. Ignitor had busted at tip. I assumed it was a bad ignitor and the appliance parts store replaced it. Checked voltage again, and installed new ignitor. It won't even light up. Checked the voltage again (it was 118v), and then checked the resistance on the ignitor and it was 176 ohms. The service manual for the oven says it should be between 110 and 135. Did I get 2 bad ignitor's? Is that likely, or is something else going on? Is there something else I can check?

The Brand is DCS, it is made by Fisher-Paykel. It is over 10 years old. The ignitor he gave me to replace the original was RobertShaw 41-206. It is flat. https://www.robertshaw.com/Produ...s/41-206/?cat=2147484238

Fisher Paykel looks like this

Those igniters run on 110 to 120 volts AC. You should be able to wire on up to a lamp cord and test them. Just be careful. They get yellow hot after a couple of minutes and will set fire to anything to close to them. Actual resistance varies from one to the next. I personally never go by resistance.

Its quite possible to encounter two bad igniters. Perhaps the third time will be the charm. Good luck.

The parts of the igniter circuit are in series. The power comes from the range's hot side of the cord, goes to the control (electronic computer or mech. thermostat) then it goes to the gas valve then to the igniter and back to the neutral line on the cord.

Anything that breaks the circuit will stop it from glowing. I usually take my volt meter and work my way through the circuit until I find what is stopping the power.
