Dryer shut down before clothes were dry
... I figured it was some over temp switch but then read about the gas solenoid problems others were having... bought $100.00 worth of parts... saved the old just in case down the road I might need them... figured a service call would cost me that much... now lots of new parts... and a working dryer. Done!

Dryer stopped working with no power detected
Based on my research, the thermal fuse could be blown out so I tested it and it was. I've replaced the thermal fuse, high-limit thermostat and cycling thermostat. bam! it's up and running again. I'd highly recommended ordering your parts thru PartSeclect..the order was easy and shipping is quick. Thanks

Cycling Thermostat Failed
DIAGNOSTICS: Unplug dryer to reset controls. Remove lower cover. Plug back in. Start dryer. If flame starts and goes out in a few seconds, probably the cycling thermostat (located centrally near bottom of dryer) is bad. It fits in the center of the thermostat heater (not replaced). Use the on-line schematic. I reset the controls (as above) again and jumpered the cycling thermostat. This time the flame stayed on. I turned off dryer before High Limit Thermal Fuse could blow out. Only a trained electrician should do the above.
REPAIRS: Decided to remove main cover, to get better angle on thermostat screws. Unplugged. Removed door first. Be gentle with wires. Be careful with drum, it will simply fall out if jarred. Remove two screws for cycling thermostat. Remove wires, replace cycling thermostst. Reassemble. Be sure drum is still on rollers on back and anti-friction strips in front.
SHORTCUT: If you use an articulated socket wrench on the thermostat screws, you can save your self the trouble of removing the front cover, door, and possibly drum.

Dryer would cycle on once then wouldnt continue to heat to dry
I first unpluged the dryer then removed the bottom cover (two screws) then found the correct socket and removed the components and replaced them wire for wire. PLugged it back in and strated the dryer and watched the process. Unforunately it cycled twice and then stopped working. I went to a local appliance store to buy another high limit fuse because I thought it blew and happened to talk about the situation to a man behind the counter and he insisted it was the gas coils so I bought some and replaced them and its working fine now without replacing any more components. Im not a aapliance repair man but mechanically inclined but experience does pay. Hey, everything is easy if you know how...

My heater would not HEAT!
I asked the Gas Co. if they can come out and relight the pilot to my dryer... (which is common for gas dryers) He tested the equipment and told me that the thermostat was the problem. Most places was looking for around $160 for parts and labor. Well, I saved around 130, as I just simply replaced the thermostat. DONE DEAL!

Dryer would not start
Remove bottom panel from dryer. disconnect wires off of Limit switch. Unscrew 2 screws, remove old switch. Reverse to install. Important, if limit goes bad you need to replace cycling thermostat or chances are the limit will go out again. (Limit on back wall of dryer). The cycling thermostat is right under the lint screen. Remove 3 wires. Remove 2 screws, remove switch. Reverse to install new cycling thermostat. Toatl cost of 2 parts used 16 dollars and change. Thanks

Dryer wouldnt heat up
Took the cover off the front of the dryer by removing the two screws that hold the cover in place. Then removed the two screws that held the heating element in place and removed the heating element. Removed the screws that held in the theremostats and then disconnected the two wires and put them on the new thermostat. Rescrewed them in with excisting screws and then put the heating element back in. Put the cover back on and turned on the dryer, and presto it all works again.

Dryer not heating / drying properly
Removed lower and upper panel on front of dryer, realized I did not have to remove upper but it was better visually. I replaced coils using old cage replacing two coils paying attention to position. Next I replaced cycling thermostat and boosting heater (which piggy back). Lastly I replaced Radiant flame sensor (which was working, but old).
Everything worked perfect for a little over a hundred dollars, a repair person would have cost me $ 75 to $ 80 dollars for a handshake plus parts and labor. I am very pleased.
