How to Troubleshoot & Replace Whirlpool AP6008294 / WP338906 Flame Sensor

Installed a new ignitor and Flame sensor all is working fine now, the technical staff was very helpful and friendly with helping me with my issue. 

Replaced igniter and all the sensors as a precaution. 

Researched the likely causes for the failure on the Web using Google search and YouTube. Ordered all of the replacement parts that could fail and cause this problem. Also ordered a replacement belt. Removed the lower front panel, tested the fuse with an ohm meter and found had blown. Tested and found the other sensors were OK. However found a blanket of lint covering the inside of the machine. Needed to remove the upper front cover, dryer top, and drum to completely vacuum out the lint that had accumulated in the machine. Removed the fan housing. Cleaned the fan and housing thoroughly and replaced the covers, sealing with new foam tape. Replaced the fuse and the thermostat. Oiled the rollers and replaced the drum using the new belt. Reinstalled the top and front covers. Checked the vent line for obstructions. Tested the machine. The igniter glowed, the gas valve opened and the flame lit! Watched as it cycled on and off several times. Replaced the lower cover. All done! Packaged up the unused parts and returned them for a full refund. I didn't mind paying for the return shipping, considering how much I sacked by doing the repair myself. Five full loads later and the machine is running fine. 

I was going to order a thermistat figuring that was the problem. I did some instant messaging with one of the techs and by the time we were done it was decided that I should replace the gas valve coils and the flame sensor. I watched the videos also just to see where the parts were located and how to get there. The videos show taking the front off the dryer & pulling the drum completely out for easy access. Once I got the front off I saw that by using a bungy cord to hold the drum in place and maybe slightly elevated I was able to get to both parts and easily replace them. I also took the time to use my shop vac and clean out years of lint accumulation you can't see or get to while I was there. Total time, about 15-20 mins. Dryer works great and is nice and clean inside and out! Thanks for the help! 

I found the part on the parts list and ordered it 

Visited a repairman, he gave me a list of possible parts needed. I replaced them all for less than one repairman service call. The parts arrived in less than 3 days. 

Disconnected power, removed one screw, installed new sensor. Dryer back in operation. 

Didn't take any chances put in new flame sensor, high limit stat. & Dryer gas valve kit. Works great, hasn't heated this well in a long time. I also cleaned out the venting system from the filter side and the exhaust side. surprisingly the hardest part to put in was the high limit stat. I thought it would be the easiest. 

AppliancePartsPros was the EXACT SOURCE I needed to fix my Amana clothes dryer. I found them with a web search and was VERY IMPRESSED with their web site. The web site has parts for a very large amount of appliances, shows photos of each part and THEY EVEN HAVE A VIDEOS ON HOW TO CHANGE EACH PART !!!. The prices of the parts were reasonable to me and arrived in just two days. With the videos to follow I had my dryer working within ONE HOUR! I will send their wed site to my sons.

I replaced the pilot sensor switch , which when tested allowed continuity to flow thru, also decided to replace the pilot glow stick , dryer is 10 years old. Simple install, had parts and had it running in 20 minutes. I ordered parts on Thursday and the dryer was up and running Saturday by noon, if I called a repair person it would have been a couple of days before they showed and if the parts were not in his truck another call would have to be made, so the process thru you was fast and I would give the service a ten star rating
