The fault is likely the MAIN BOARD.
New parts can be a "dud".
The IGNITER only needs to provide heat for the FLAME SWITCH to "sense" it and to provide a source of ignition of the gas.
Amperage (the gas oven type) has no role in dryer burner ignition.
The gas coils are within specification (ohms).
The MOTOR SWITCH is okay--since the IGNITER functions.
The THERMOSTATS & THERMAL LIMITERS are good---the IGNITER is working.
Generally---when a FLAME SWITCH fails---the IGNITER will not glow or the burner never ignites.
Try replacing the FLAME SWITCH (p/n: 6501EL3001A
) as this is not only a possibility but is relatively inexpensive.
If that fails to resolve the problem...
This still leaves the MAIN BOARD & the WIRE HARNESS as the most likely suspects.
