The ignitor (P/N 279311
) on my gas dryer had gone bad (no continuity Ohms) so I purchased a new one and replaced it. The new one still does not glow. I checked the input voltage to the ignitor and it reads 30 volts (clearly not the 110 volts needed to energize the ignitor. I checked the thermal fuse (P/N 3390719
) and high limit thermostat (P/N 3403140
) and have continuity across both of them. I checked the thermistor (P/N 8577274
) and have no continuity so I know this component is bad and needs to be replaced.
My main question is that I also checked the radiant sensor (P/N 338906
) and have no continuity on this component. Is this sensor normally open and closes when it senses heat from the ignitor or is it normally closed? This will help me determine whether the part needs to be replaced or not.
Is there anything I may have missed that would account for the low voltage reading at the input to the ignitor? I did the diagnostic test on the control panel and everything seems to function properly. Also, I checked the resistance on the gas valves and they all check out within specifications.
I need to order the parts and just want to make sure I am getting the right ones this time around.
