I have a Maytag LDG7400 Dryer, will these coils work on my dryer? What does the main and secondary coils do? Is there a way to check of either one or both of the coils have gone bad?
ANSWER Hello Chris! Yes, the coil kit 279834 will work on your LDG7400 model dryer. The main coil is used to open the gas valve to allow gas through for the unit to ignite. The secondary coil is used once the igniter is lite to maintain the heat. You can test the coils using a multi-meter. The two prong coil will read 1,000-1,300 ohms, and the three prong coil will read 1,300-1,400 ohms across prongs 1&2, and 500-600 ohms across prongs 1&3. Hope this helps!
