I checked repair videos on line. Put in my brand and model. You tube had a video how to dis assemble my model. Video made it really easy, I would never have figured it out. Now checked videos from Appliance Parts Pros to troubleshoot the fix. Checked all thermostats and fuses with ohm meter they checked out perfect. Finally checked the igniter found out I did not have resistance. I was also concerned I may need new coils (solenoids). In visiting with customer service he explained replacing the igniter should solve the problem as the coils were controlled by the igniter. I ordered the part it was delivered the next day regular freight. Easily installed the igniter and it glowed right away but the dryer still did not light. I thought time to order the coils. However, I went back to check list and checked the gas line, sure enough in re installing it it was blocked by the old pipe joint cement I used. Once I cleared both ends the dryer ignited and I have one happy wife. To be honest I am pretty proud of myself. All videos were excellent and a major help. Thank you Appliance Parts Pros for your excellent customer service and speedy delivery. Only spent $22 total. Local part store wanted $35 + and I didn't have to drive there. Not sure what it would have cost me through and appliance repair service. This is the third time I have used Appliance Parts Pros and I have been satisfied on every occasion. Once they referred me to a wrong part number for a replacement refrigerator door shelf. When I received it i called Customer Service and they immediately sent me the correct door shelf. Can't get any better than that.
