No heat, would not light because igniter burnt out
Unplug dryer. Remove the front bottom panel of dryer 2 screws, then unplug wire connector to the old igniter then unscrew one screw holding ignitor then wiggle out. Open new igniter wiggle back in place insert screw tighten, (getting this screw back in is a little hard) replug wire connector to new igniter replace front panel with two screws. Plug in dryer and there you go drying clothes again. Wife all happy again.

No Heat
Thermal fuse was blown so I replaced it. Still no heat. Hi-Limit thermostat and Cycling Thermo. had continuity as did flame sensor. Igniter tested 66ohms. I placed a wire jumper across the Hi-Limit and the igniter glowed, solenoids opened and gas came on. I orderd the Hi-Limit and since both "overheating" limiters were defective I decided to order the cycling thermo just in case. The Hi-Limit was received in 2 days but the Cycling Thermo was backordered. In the meantime my wife got antsy so I went ahead and installed the Hi-Limit and put her back in service... ...for one load. I wasn't certain if I had fried the "limiters" again but since they had continuity and I could measure continuity all the way to the Igniter I decided that it HAD to be the cause. I ignored the flame sensor since it never came into play without the igniter glowing... The igniter arrived and measured 56ohms. Hmmm... After installing the problem was solved. Word of advice: If the thermal fuse is blown and even if all else in the circuit SEEMS ok, go ahead and order the Fuse, Hi-Limit and Cycling Thermos, and the Igniter. It will take you about 30 minutes to install and you'll reduce your out-of-service time! Good luck!

Dryer would only heat at start up for one cycle
Ohmed coils and both had continuity so I changed radiant heat sensor. No bench test for Radiant Heat sensor. Same problem. Changed both coils and dryer works fine. Weak coils were my problem. I read thru the same issues in Parts Select forum and it said Radiant Heat sensor was problem 25% of the time. With coils having continuity and no ohm value specified for coils I made wrong choice but, I have spare parts and look for another 10 years of life in the dryer. Nice to have this forum to research appliance repair. Very helpful for parts location and installation. Dishwasher is next!

Lint has been bypassing the lint filter and building up in the fan (and duct)
I noticed that drying time was increasing. I took the covers off the dryer to reach the fan and discovered that the squirrel cage fan buckets were packed with lint, and therefore not moving the air as intended. This was because the original lint filter caught most of the lint, but some bypassed the lint filter and then built up in the fan wheel buckets. The lint bypassed the lint filter because there was no felt gasket on the original filter as far as I can tell. I replaced the lint filter...and the replacement filter includes the felt seal (and fits tightly in the slide). The original lint filter has a provision for the felt seal, but I don't recall ever seeing it (and I did not see remnants of it in the fan or duct). As a matter of fact, I was always suspicious of how loosely the lint filter fit in the slide. The felt seal is not available as a replacement part from Maytag. That said, felt material 3/16"x1/2"x10ft is available from McMaster-Carr...and it fits nicely in the original lint filter.

Disconnect power supply, remove power cord from dryer, remove dryer vent tube from dryer, remove 2 Philips screws from power connection on dryer, remove nuts from back of dryer, remove back of dryer. Locate idler pulley at bottom of unit at the rear of the motor, pull pulley back to loosen belt and remove from pulley, remove pulley retainer clip, remove pulley and rear washer from shaft and inspect shaft for wear or rust. replace washer and pulley (no specific direction to replace them, washer first then pulley). Reverse above procedure to reassemble. This is for a front load dryer, a top load dryer is different.

Dryer would not heat up properly. It would heat initially but once the heat was off it would not come on again.
I followed the advice posted by other customers. I took the front off the dryer, put the door back in place and ran a cycle. I could see that the igniter was heating properly, but no gas was flowing. Based on what I read I concluded that it was a problem with one of the gas valve coils. It was relatively inexpensive to replace both (and the dry is 10 years old), so I didn't go to the trouble of determining the bad one. I replaced them both. Obviously I unplugged the dryer (no need to turn off gas). There were 2 screws that held the bracket in place which holds the coils. I disconnected the coils, removed the bracket screws, replaced the coils, reattached the bracket screws and reconnected the coils. I then reattached the front plate to the dryer. It was very easy and took about 20 minutes and I had never worked on a dryer before.

Convert New Dryer to Propane from Natural Gas
1.Unplugged the connections to dryer door
2. Removed dryer door, front cabinet,popped off the drum belt (this is done by feel),unplugged the drum from cabinet, removed drum, all to get to the gas element inside at the bottom of dryer.
3. Unplugged the connection to the element, then removed unit to get to the burner parts.
4. Replaced the natural gas burner element with the LP gas element.
5. Re assembled dryer and tested.
*Note: Actually my son did the work while I read the very easy to follow directions. Since neither of us has disassembled a dryer before, the thought of taking a brand new dryer all apart was more daunting than the actual task.

Gas dryer would not heat - pilot lit briefly then went off
Same as others.
1. Unplug dryer from power source
2. Use nut driver to remove two front screws at bottom of dryer
3. Disconnect cable connected to Secondary Coil (this is the coil towards the rear of the dryer)
4. Use angled phillips screw driver to loosen screws holding cap on top of the two coils. (Angled tool not required but seemed easiest to me)
5. Slide top cap back towards lock screw to allow coil to be lifted out
6. Remove and replace secondary coil
7. Replace cap, tighten screws to lock in place, reconnect cable to coil
8. Restore power to dryer, test and confirm gas flame stays lit
9. Replace lower front panel on unit

PartsSelect a great resource to use for home repairs like these. My first time using site and doing this type of work, now PartsSelect my first source to go to on such items.
