Question about Maytag Atlantis MDG7400AW Gas Dryer
The coils are difficult to test. You can use a multimeter or ohmmeter and check for continuity, but the problem is that a coil may be sticking open only after heating up, so you can see the difficulty this would present. If a coil is suspected of being faulty, it is best to replace both (all) at the same time. These coils are what permit the gas valves to open and they can cause a no light or a cycling condition. Really sorry for your trouble and I hope this helped. Best wishes.

Testimonial: "thanks for the info very helpful"
By "coil" do mean eliment ?
This post indicates that you have a gas dryer.. here would be no "coils".

Ignition Coil Primary Circuit Test
Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is zero point five and zero point seven ohms. If primary resistance is not within this range check out test results below.
Ignition Coil Secondary Circuit Test
With the ignition coil removed from the motorcycle and the ohmmeter set to the RX1K scale place the ohmmeter leads on the secondary coil windings B (middle terminal) to
R (rear secondary terminal/socket), B to F (front secondary terminal/socket) and check for secondary coil winding resistance which normal resistance range will be 5.5-7.5K ohms. If secondary resistance is not within this range check out test results below.
A low resistance value indicates a short in the coil winding which requires coil replacement.
A high resistance value might indicate that there is some corrosion/oxidation of the coil terminals requiring the coil terminals to be cleaned and the resistance test then repeated and if after the test is repeated the resistance is still high after the terminals were cleaned the coil must be replaced.
If there is an infinite ohms or no continuity) resistance value the coil is open and must be replaced.
