Recently purchased a Whirlpool Estate TGDX640PQ1 gas dryer on Craigslist. For what it's worth, we transported the dryer home on its back. Once home, I found that it does not heat.

When first started, I hear a loud sound and can see that the burner igniter light glows (via the lower left view port). After a few seconds I hear a click and the glow dies down and the loud sound goes away. However, I do not see a flame.

After a minute or so I hear the loud sound again and the igniter glows again, then dies out. Again, the loud sound dies with the glow. Still no heat. Can someone advise what the malfunction might be? Thanks.
