One of the roller assembly froze up & had a flat spot on it. There for causing the drum not to rotate. Pulled it out replaced the roller & up & running.
1 of 4 Drum Rollers Froze Preventing drum rotation.
Replaced idle pulley wheel, worn drum belt and all 4 rollers (1 frozen) due to dryer age. Site video re general disassembly/re-assembly easily adapted to this model and very helpful with exception of replacement of drum rollers. New rollers received (AGM75510755) were pre-mounted on included shafts. This required removal of existing roller shafts to replace with new shaft/roller units. Site video shows placing a new roller on existing shafts after removing a plastic retaining clip. New roller/shaft assembly is a better option and fortunately I did not order extra retainer clips! Rear drum roller shafts have small carved out space to fit a box end wrench to remove shaft nut. Watch out for sharp edges on internal steel parts!
Initially replaced igniter. Didn't think it was bad though. Read other suggestions on another website. None were the correct diagnosis for my situation. And when I figured it out they did not offer correct part. The dryer thermistor temp sensor (probe sensor) is what I replaced. Found it on Parts Select. I did replace other parts also. But that's the one that ultimately was the issue. Was not hard at all if one is even a little handy.
I took the dryer apart. You have to take the top off, then the door/front off. There are wires & other parts that need to be unhooked as well. A flat tip screw driver can be used to pop the top off. The screws were all phillips. Once you take that all apart, then you can access the drum. I bought the belt because I thought that was what was wrong with it. Turned out to be hair in the drum rollers. Took those all off & put wheel grease on each of them, put new belt on (since I had it LOL) then put it all back together. Make sure everything is lined up correctly otherwise you will have to take it apart & reline (which I had to do) I am a 49yr old female & was able to do this repair on my own!
I watched video by searching by the part number. It was recommended by Sales Lady(Can't remember her name). I removed door from the unit and then removed all the screws on the door. There was about 16 of them. I then pushed on the 2 plastic clips which raised one side of the door. This exposed where the Door Strike goes into. I removed the screw that holds Door Strike in place. Inserted new Stronger Door Strike and lined up hole with screw slot. Screwed back in till tight, thus locking Door Strike in. Inserted all screws back in, and attached door back to unit. Tested fine and have now done several loads no problems. A $4 part would have cost me hundreds by service company. Thanks Part Select!
Completely had to dismantle the dryer to get to the igniter. The screw holding the igniter is a SOB to get at for extraction, and even worse putting back.,
