Have a whirlpool duet gas dryer not heating, but running as

Resolved Question:

Have a whirlpool duet gas dryer not heating, but running as for as the display is on and the drum turns. Model #: GGW9200LW0.

Things I have tested so far:
thermal fuse - OK, both by meter & just connecting the wires
ignitor - test at 72 ohms of resistance
flame sensor - zero ohms of resistance
thermistor - about 0.5 ohms

The dryer is not heating consistently. The ignitor glows and we get gas then flame for a 1-3 cycles;
afterwards, the ignitore glows with NO FLAME.

Things Replaced:
Gas Valve Solenoid Set, Control Board, Flame Sensor

Anomaly(or best clue yet?) - I put the dryer in diagnostic mode and push the start button, ignitor glowed and a big bright flame when down the burner funnel.

Any suggestions?

thanks for your assistance, -Shelton

Hi, my name isXXXXX am hoping that I will be able to help you with your problem today..



Unusual that you replaced the coils on the gas valve and this happened, this is classic of bad coils, maybe you got a bad set that you installed, I would try another set of coils in the unit...

Here's the resistance numbers for the coils:

Original Set: Terminals Resistance
1 to 2 2022 ohms
1 to 3 587
4 to 5 1320

Replacement Set:
1 to 2 1992 Ohms
1 to 3 580
4 to 5 1335

Do these number represent bad coils?
