Remove back panel n u can see the sensor and easy to replace thanks to the print out i was provided love this website

I inserted the clip

I had an issue where I was not getting any power to my ignitor. After replacing the ignitor with a fresh one, the problem persisted. Next, I went hunting all the fuses and therrmostats for continuity. All seemed fine. So finally I decided to jump the flame sensor which is located on the outside of the flame tube. WHALLA! It ignited the glow plug. So with one 1/4"" nut driver I removed the single bolt from the unit, then I used a pliers to remove the two wires from the old unit. I replaced the sensor with Tue new unit and all was well. It took less than 5 min once I diagnosed the problem.

took old one out then i had to strip the connector off new one was to big...

Sensor is in the front lower left. Gas off, electicity off. Removed two screws for the filter, pry/lifted the top up and taped it too the overhead cabinet, removed two screws inside top of front panel, lifted pandel with door closed staight off. Two screws to remove the flame sensor braket. unplug the old sensor install the new one and reverse everything. With others suggestions I purchased temperature switches etc. but the radiant flame sensor was the problem. I now have some spare switches for future. Excellent company and very quick service. Oh, Sears wanted 200.00 just for the service call, I live rural.

Turned out to be the primary coil on the gas valve. If you remove the cover of the coils and wait for the dryer to try to start the flame the coils are energized, a magnet is turned on. By lifting the coil you should feel the magnet if the flame is on. If the flame does not come on after the ignitor fires check to see if the coils are energized. If not buy the set, it's cheaper then purchasing them separately.

Dryer stopped heating after a few days of it being an intermintant problem. I ohmed the heating coil and it was fine @ 12-15 ohms and the 2 sensors were open so I knew they were not the problem. The only item left was the Heater Relay. As soon as it was changed, dryer operated as it should.

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!

loosened two screws on back of top,lifted top away from front panel.it just lifts off front corners,removed two screws at top corners.lift front panel up and out,this panel supports dryer tub,remove slowly,unplug door switch parts are located left side bottom two screws holding in had to have wife hold drum up to put front panel on

A year or so ago I replaced one drum wheel. The dryer worked fine for months until it started sqeaking again. When I removed the wheels again the shaft was no longer round but half moon shaped. this allowed the drum to drop lower than it's supposed to. consequently the drum ate through the back drum support. I replaced the back drum support and the roller shafts, in addition to two new rollers. It works great now. The more difficult part of the repair was replacing the rear drum support. It is screwed in from the back and requires two people. Everything else I did by myself. The lesson: If you replace the rollers, be sure the roller shafts are not worn. An asymetric shaft eventually causes more parts to wear out.

I watched the video

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.

First changed the ignitor, which did not fix the problem. Unpug Dryer. Removed the front panel by taking out the 2 phillips screws and pulling the bottom of the panel out first, releasing the top clips. Remove the clip holding the coils on and replace them. Plugs just pull off, each are different so cn't mix them up. Both sensor and thermostat are pretty easy to get to using 1/4" drive socket. the screws can be a bit tough to get back in, but be patient. Wiring is pretty straight forward, remove from the old part and put on the new, same orientation. This is a good time to vacuum out the bottom of the dryer to get any loose lint out. Return the front panel, tilting out at the bottom to engage the top clips. Plugged it in and worked like a charm

The replacement part just snapped into place. (The old part had fallen out) It took less than 30 seconds to do the repair.

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.
