I realized my load of laundry was still wet after a normal drying cycle. My first action was to turn the dryer on (2010 gas Maytag centennial) and open the front port to look at the ignitor coil. It never turned orange so I knew there must be a problem with the primary circuit. I shut off the dryer, disconnected the power, pulled it away from the wall, shutoff the gas, and removed the back panel. I then disconnected the wires for the thermal fuse and checked its resistance with a multimeter. When it didn't read 0 ohms and instead read "OL" for "open line", I knew I had found at least one issue and I'd start by ordering a replacement for that. I knew there could potentially be other issues, but I wasn't about to start ordering random parts without acknowledging the first issue. In addition to the coil not turning on, my dryer had a problem with the door switch for a long time. Fixing it wasn't a priority because it had failed closed. This made it so the dryer would still turn on (because it always thought the door was closed), but it wouldn't turn off the drum when you opened the door mid-cycle or allow the drum light to turn on. This was a minor annoyance, but now that I was ordering an important component to getting the dryer to heat, I thought it was the ideal time to also replace that piece as well. Once the parts arrived, I installed the new components with no issue. The website clearly identified that the parts were replacements for my existing part numbers and that turned out to be the case as expected. Before putting the back plate back on I plugged the power back in, opened the gas line, and turned the dryer on to a heat cycle. I peered through the view port on the front of the dryer and watched the ignitor coil glow orange and the flame kick on. I also tested the door switch by opening the door with the dryer running and the drum stopped and the light turned on as it should. After seeing that I cancelled the cycle, disconnected the power once again to prevent the possibility of shorting any components, and finished reassembling the dryer and placed it back in its compartment. Then I successfully ran 8 or 9 loads because my laundry had been piling up for the 6 days I had to wait for the parts to arrive. The dryer works like new again!
