How to Troubleshoot & Replace Whirlpool AP6007994 / WP33002789 Igniter Assembly

I watched a video on the Appliance Parts Pros website and then took the cover off the front of the dryer. I didn't have an Ohm meter to check the electrical but based on the video decided it was probably a problem with the igniter. I took the igniter off and noticed it had a burnt spot on it. I ordered a new part from AppliancePartsPros.com and the part came within 2 days! I easily installed the new igniter and it worked perfectly! 

Replaced the igniter assembly. If you're trying to diagnose this problem, remove the original igniter assembly first. As soon as I removed it (one screw) I could see that it was burnt out. More than likely, this will be your issue. It's a very simple repair. 

Once I found testing information (also on the APP web site), and figured out how to get to the main components (top, control, and front panel removal)I was able to determine with an ohmmeter that the secondary gas valve coil (the one with three pins) had an open circuit. The primary coil tested out of range, but no matter: the coil kit came with both. After replacement, it fired right up, and is actually performing better than before. 

My wife told me that the clothes in the dryer were not drying, do something. I checked and guess what she was right.I looked up HOW TO on the internet to find out to remove the front panel. Once I found out to remove it the rest was easy. I turned on the dryer without the front panel and I noticed was the igniter did not glow. I turned off the dryer, Loosen the screw and unplug the Igniter Next I looked up the part number and order it from Appliance Parts Pros and in two days I received the part, installed it and the wife was happy again. 

REPLACED GAS VALVE COILS FOLLOWED YOUR VEIDO AND IT WAS RIGHT ON THANK YOUVERY MUCH JUST GREAT SERVICE YOU OFFER FROM START TO FINISH 

Changed the Igniter Assembly 

An internet search said it was either the fuse or the igniter. Since the dryer was 17 years old we figured it was time to replace both. APP made finding the right parts for our model super easy and even included a video of how to replace that part on the part page. How convenient! We got the job done in about 20 minutes, 4 days ahead of the earliest time a repair man could come look at it. So nice to be wearing clean clothes again! 

The igniter was the problem. Easy fix. 

I initially decided to replace the flame sensor (most common failure), the high cut-off thermostat, the thermistor & moisture sensor (since the auto cycle didn’t seem to work at all), and the igniter (after I may have damaged it while cleaning the heat chamber). I added the remaining thermostat since everything else was being replaced. This did NOT fix my problem. After several google searches, I came across a post that described weak gas valve coils that would work for several cycles, then would not be strong enough to open the valve. This sounded exactly like my situation, so I ordered the coils only ($18 versus $260 for the entire valve assembly). This fixed my problem. The thermistor and moisture sensor were probably good replacements since the auto cycle works fine again. 

After reading on line about problems similar to mine, I bought the coil kit and a new igniter. The install of the coils was very easy, I didn't install the igniter, I'll keep it as a spare.
