Completely vacuumed cabinet and duct work. No blockage.
I jumpered High Limit switch, P/N L220-40F or Maytag P/N 303395, and it runs.
I removed the burner, found some rust in the tube, assumed it re-directed the flame and burned out the switch. Bought new switch and new burner and installed. It does the same thing.
If I jumper the high limit switch, it runs. It doesn't seem like it is overheating. What am I missing? Is the new sealed in Maytag bag high limit switch bad? Is it supposed to be in an Open or Closed state before applying heat?
Attached is a picture of the burning flam. Looks good to me.
Any help would be greatly appreciated.
