My maytag neptune dryer heats up for about 20 seconds with the gas and then stops. it doesn’t heat up again after that. what is the problem?
Hi,
One of the two coils on the gas valve maybe failing.
Where is the coils and how do I check which one of any are failing
The coils are located on the gas valve. I would replace them both at the same time. You can order them as a set. They are cheap and easy to replace. Here is the service manual for this model dryer. It will tell you everything you need to know.

Then this is the service manual you will want.

so this is what I found:
The gas is ignited but the flame goes out. If a
normal ignition takes place and after a short while the
flame goes out, check for the following:
• Radiant sensor contacts opening
prematurely.
• Weak gas valve coil may open when
stressed by higher temperatures.
• Weak Hi-Limit
• Poor venting
• Bad drum seals
you think its the coils? am I supposed to replace the 2 coils on the gas valve assembly?
It could be the coils, here is some more info on testing the coils.

Sometimes they can be hard to test because they may test fine when the unit is cold.
