The dryer would light off initially, then no more. I read the resistance on the coils, which were outside the required range, so replaced them with new coils that tested correctly. Now, the dryer will not light at all. I'm told the gas lighting circuit is wired in series, so if the igniter does light off everything within that circuit is operating as designed. So, if the igniter worked with the older coils and the new coils won't allow it to heat up, does that mean the gas valve is somehow messed up? Or what do you think? Any ideas gleefully received...
