My dryer heats up when it's first started but when it stops for any reason or after certain time running it will stop heating. The igniter goes read hot and very bright but there is no gas ignition. I replace all of the sensors; temperature sensors and flame sensor and the problem still continues. I understand that it might be the coils on the gas valve. My question is how do I know that it is the coils and not the valve itself. I removed the gas valve and exited one of the coils and it works fine. The second coil it does not but if I switch the coils the one that did not work before works now and the one that did work befoer it does not in the new position. Is this an indication that the problem is the valve itself? I'm at a lost and ready to purchase a new valve (Part number 504091) but I wonder if the coils (Part number AP3094251) alone will do the job. Another question, if I purchase the valve Part number 504091, does it comes with the coils or I have to buy them separately? Please help.
Thanks,
Ed

Great. Thanks, I replaced the coils and the dryer is now working great.:D
