Maytag gas dryer model LDG7500AAW

Dryer runs but ignitor does not glow and no flame or heat.

Ignitor has continuity and looks pretty good.
Only about 38 volts AC going to Ignitor.
I replaced the coil set but still only 38 volts.
Thermal Fuse has continuity
Flame sensor has continuity
screenshot 1 has multiple connections but not sure how to test that.

Thank you

Hi,

The problem is the timer is not supplying the full 120 volts to make the ignitor glow, or you have a broken/shorted wire.
Check for any broken wires from the timer to the ignitor first.

Here's the timer for your model:

Look for a broken wire then from the timer to the igniter Jim, that's all it can be at this point.

Hey Jake.
No issues with wiring. Everything looks OK.
But I took another reading on the flame sensor. This time with the wires removed. Duh
No continuity so sounds like that's the problem?

That's what I thought you did in the first place, because its extremely difficult to get the meter probes into the plastic connector, when its connected to the igniter, to get a good reading.:)

Here's the igniter for your model:
4391996 Flat Style Dryer Igniter


Here's the video to ohm test it, in case others need to ohm test it too.:)


Let us know how it goes.

The ignitor continuity is good. It's the flame sensor that wasn't. The terminal on those wires are metal. Screenshot 3 above.
Part is on order.
