Hi all,

Have had this range for 6 years. Gone thru a few repairs. Recently noticed the oven making a wooshing noise when igniting. I found the bake burner had some corrosion near the ignition orifice. I replaced it and the HSI. After this the HSI would not glow. I checked the HSI at 280 ohms. Found no voltage at T504 and T505 when bake set to on. Broil works fine.
I ordered a replacement main board from partsdr per the tech manual and I still do not have the HSI glowing, and no voltage at T504 and T505..

What am I missing? I'm checking T504 and T505 with my auto ranging meter with the blue wire harness removed.

Much help appreciated.

You must of received a bad board then.

Connect the blue wire harness back in place, then remove the electrical connector at the BAKE Ignitor and Test the voltage at the BAKE igniter electrical connector WHILE BAKE is ON 350.

Here's the main control board(PCB) for your model you can order:
