This Roper dryer was taking quite a while to dry clothes so I took it all apart and gave it a good cleanup. It was working but just not doing so good. The filter housing was totally blocked with lint. I tore it all down and took a few photos:
To get inside this puppy you yank out the filter and remove 2 screws. I went to the parts store and purchased a new filter, you will see why in a minute.
Use a putty knife to release the plastic clips in the front and raise the top.
Take the door switch wires off and get that front panel off.
Lift up the front panel to keep from breaking the clips at the base.
This is why the dryer wasn't doing too good of a job. Busted filter didn't help either!
I cleaned the blower housing. See those 2 amigos on the blower housing? The Klixon is the temp control. It judges the air temp and turns the element on and off throughout the drying cycle. The white skinny thing is the duct fuse. It is a wonder that fuse didn't melt by now with all that lint.
I took a water hose to this housing and washed it out real good and let it dry before re installing it. To get it out you remove 4 screws at the base and 2 screws on the bulkhead and come out the top with it. Newer models come out the back. Older models must come out the top.
This is a photo from a previous job, I screwed up the roper photo (real fuzzy) but it mounts just like this one. It helps to have someone hold the drum while you stick the idler in the floor and raise it up,loop the belt through and onto the motor. Make sure that belt is not twisted or you will be a buying another belt.
Oil the rollers using Zoomspout oil. It is safe for dryers, all major appliance, HVAC applications and it only cost a few dollars at any Ace hardware store.
While you are at it oil the idler also. Work it by hand till it turns freely.
The spring tension from the idler keeps the belt from coming off.
This dryer don't look like much from the outside but it is now ready to dry some serious clothes, no parts needed! Let me tell you it is way better than anything new on today's market. Don't trash it. Clean it up!
