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. http://appliancejunk.com...wnloads;sa=view;down=386 btw, did you ever get the dryer working from your other topic. http://forum.appliancepartspros...ts-error.html#post616215 You seem to be having your fair share of dryer problems. ;)

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?
