REX6646AW1 Roper Dryer - Instructions

First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils.
Not knowing what the problem was I started looking at the coils and could not see any broken parts.
So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of needle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading.
I replaced with a new one and put it all back together the way I took it apart.
Then I plugged it in and it worked first time, I now have warm dry clothes.

Removed the two screws that attatch the lent channel to the top of the dryer, then lifted the top of the dryer by pushing in on the two locking tabs located at the front , left and right , corners of the dryer top with a small flat head screw driver. The top of the dryer will fold back out of the way. At this point I removed the two 1/4 inch screws that are located on the inside of the dryer front left and right corners that hold the front panel/door to the two side panels. Now I was able to lift the front panel up and set it to the side. The bottom of the front panel that contains the dryer door that I just removed was held on the bottom by two clips that slide into slots on the front panel and did not require any removal to disconnect the bottom of the front panel, just pull up on the front panel. Since the tub was held in place by floating on a seal at the back of the dryer and a seal on the front panel , which I just removed the tub is now free floating except for the two alignment roller wheels at the bottom of the tub. It is easier if you lay the dryer on its back at this point with front of the tub pointing up. I pulled the tub out and cleaned the years of built up lent and removed all the pieces of the old , destroyed, belt. Note, the belt tentioner is located at the front of the motor which on the bottom right hand side. If your belt is broke like mine the tensioner may/will fall to the back of the dryer when you tilt it back, but do not worry. Once the dryer was cleaned up I put the tub back in place , still on its back and made sure the two alignment rollers were in place and rolled freely when the tub was turned by hand. Another note, my original belt tensioner did not have a rolling wheel that the belt rode on , but was a semi-circle smooth surface that the belt remained in constant friction with when the dyer was running, so I made sure the replacement tensioner I ordered with my new belt did have a rolling wheel that the belt would ride on, which I believe will reduce wear and extend the belt life. The new belt came with a diagram of the belt and tensioner routing which was helpful. Note: do not take the tensioner wheel off/apart when trying to route the belt. Follow the instructions routing diagram. The tensioner is held in palce by inserting the bottom back half into the slot in the bottom floor of the dryer making sure it is aligned with the belt pully on the shaft of the dryer motor. The dryer is still on its back side. Now, it was easier for me to route the belt around the center of the tub, following the marks from the original belt, and hold in in place in a few spots with masking tape and then route it thru the tensioner and onto the front pully of the motor. Make sure you have the grooves of the belt against the tub and the grooves are aligned with the pully on the motor. Now you can remove the masking tape that was holding the belt around the tub and spin the tub by hand watching the belt making sure it is not in a bind and is traveling around the motor pully , tensioner and tub freely. Make sure the tub is still sealed on the back side wall. As you turn the tub by hand you can adjust the belt by hand so that is following the original marks around the tub left by the orignal belt. Also double check the two alingment rollers and make sure they are spinning and on track. Now put the front panel with the door on by sliding it onto the two clips that are one the bottom at each side and put the two screws in that hold the front panel to the two side panels. Now stand the dryer back up and spin the tub by hand again making sure it has a good seal on the back side and on the front panel. Pull the top back down and put the two screws in that hold the lent channle to the top. I am not sure when the belt started failing on my dryer, but was amazed at how quiet it runs now. Guess I was use to the extra noise made by a dryer that was about to die. This was a cheap and easy repair and glad I did it myself.

Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.

Ascertaining the problem was the most time consuming part.

The actual repair was quite simple and didn't take but 15-20 minutes.

PartSelect is great for providing parts as requested. Unfortunately, neither of the 2 parts I ordered were on my machine. My bad for not looking at the actual part instead of the description. A word to the wise!

Received your parts, Popped them both right into place, Even though only one side needed to be replaced, I wanted them to match up. It was amazing how easy this was. My husband was quite impressed I had ordered these rather then look for either a new or used dryer from some other source.

The best part of my repair was I had everything back in service in 3 days. And one of these days was to consider just buying a new dryer. Had parts overnited and all parts fit and easy to replace.

1) Removed back - 6 screws
2) Removed dryer vent - 2 screws on top, 3 on bottom
3) Popped the top open
4) Removed Front of dryer cabinet - 2 screws
5) Removed Belt
6) Removed Drum
7) Cleaned up all lint
8) Pop off motor retainers front and back
Here is the tricky part for me.
9) Removed vent fan on back of motor.
I did not know that the back of the fan was square, and you could put an open ended wrench on it to hold it while you also have a vice grip on the front motor shaft. Then its a simple left to loosey operation. I first tryed to turn the fan blade to take it off, but proved to be to tight.
10) Repeat backwards to reassemble

While I had it apart I also replaced the Drum support rollers & Installed a new belt. Not that diffucult of a repair Good Luck, was certainly better than buying a new one at + $300.00 at Black Friday rates.

Followed electrical drawing from switch to motor, Thermal fuse was in the line and no power coming through it, removed wire and put together and tested, dryer turned on. Read statements from others at parts select and also bought thermostat because time stopped working last year. Installed both parts and cleaned dryer, works perfect including timer.

Unplugged the 220 volt source. Disconnected the vent line from the back of the drier. Removed the six screws holding the back panel with a 1/4 inch nut driver. Tipped the drier up at a 45 degree angle against the wall to give better access to the inside. Removed the screws holding the two thermostats to the side of the heater box and laid them aside. Disconnected the two red power lines to the heater element. Removed the large screw at the top of the heater box and removed the flexible bracket holding the heater box, then lifted the heater box up and away from the drier. Removed the one screw holding the heater element inside the heater box and pulled out the old heating element. The old element was open as found using an ohmeter on the two main terminals. Threw away the old element. Removed the new heating element from the box and slid it into the heater box making sure to align the terminal bracket with the hole in the heater box for the reinstallation of the mounting screw. Tightened this screw. Remounted the heater box to the two mounting slots and reinstalled the flexible mounting bracket to the top of the heater box and installed and tightened the large screw holding this bracket. Cut off and removed the old electrical push-on terminals from the two red power wires for the heater element. These were discolored and oxidated from the conducted heat over the years of operation. Using the supplied short red leads with push-on terminals already installed, I wire tied these new leads to the existing red power leads and pushed them onto the heater element terminals. Rechecked the soundness of the twisted wire connections to make sure they were tight. Replaced the back panel and reinstalled the six 1/4" screws with the 1/4' nut driever. Reinstalled the driver vent line and tightened its holding ring. Slid the drier back into position on the floor. Checked the level and readjusted the leveling legs for a steady floor stance. Reinstalled the 220 volt power connecter and set the controlls for a drying cycle. Let the drier run for aproximately 1 minute and then checked the air temperature inside the drier. IT WAS NOW PRODUCING HOT AIR. Project completed successfully and I was now a HERO in my wifes eyes. Absolutely no technical problems encountered. Just remember, unplug the drier before starting ANY repairs. To forget this COULD RUIN YOUR DAY.

When my dryer suddenly stopped functioning, without any prior signs of pending failure, I guessed that it had to be something simple, like a fuse. I did a google search and stumbled across a forum post that described the symptoms (wouldn't turn on), and the poster said that Whirlpool recommends replacing the thermostat whenever the fuse is replaced. The reason for this is that the likely cause of the fuse burning is that the thermostat is no longer properly regulating the temperature range of the heating element.

I disconnected the power source, and then I removed the back cover, and both parts were in plain view, so I simply replaced the wires one by one.

I can't believe I waited so long to find this part and do this. I got the package very fast, opened it, took the piece to my dryer and popped it into place with my fingers. It worked perfectly! this took all of two minutes and saved me from having to hold the dryer door closed with a stick. Thank you, thank you!!!

I spent nearly an hour trying to self-diagnose the problem before I wised up and found PartSelect.com. After reading just a couple of postings I went back and tested the thermal fuse. It was bad. Other posts suggested I replace the thermostat at the same time, so I ordered both. The parts arrived within three days and the actual repair took less than 10 minutes.

1. Removed the screws from the lint catcher
2. Removed the bolts from upper rear of dryer
3. Pried off the dryer top from the front (it rests on rear hinges)
4. Disconnected dryer door wiring
5. Removed bolt from inside upper front corners; removed front panel (be careful: the edges are sharp and the tumbler will fall when it loses support)
6. Removed broken belt and lint from interior parts; removed tensioner (which had fallen out of place). Note: The newer models have a tensioner pulley; my older model had a smooth semicircle that was confusing at first glance
7. Flipped dryer onto its back (for easier reinsertion of new belt and tumbler)
8. Placed new belt on tumbler; reinserted tumbler
9. Inserted new belt through tensioner, inserted tensioner "legs" into grooves on floor. Note: The belt will pull the tensioner upright when it's inserted properly (which isn't obvious at first)
10. Made sure belt and tumbler seal were properly installed
11. Replaced parts in reverse order
The process took over an hour because I couldn't figure out how to insert the belt through the tensioner. The trick is to insert the folded belt through the tensioner and onto the motor pulley. If I had to do it again, it would take about 30 minutes (including cleaning lint)

This repair was a cinch. Pliers to pull out the metal piece and a screwdriver to pry out the 'catch' part in the door. Both replacement pieces went right in. I cannot believe how easy and CHEAP this fix was, and I'm so glad I found this site!! I figured I would have to call a repairman and pay big bucks, so I put it off, but the door was getting worse--slamming it so hard to keep it shut. Again, thanks for this great site.

This is the second heating element I have replaced in this dryer which I bought new in 1977. That's right it is 32 years old and still works great!

The replacement process is simple:
One: pull the dryer away from the wall so that you have room to work in the back.
Two: Disconnect the dryer vent hose from the back of the dryer.
Three: Remove the five - 5/16" hex head sheet metal screws that hold the back cover in place and set the cover to the side.
Four: Go to the front of the dryer and remove the lint filter and the two slot head screws that hold the lint filter opening to the internal frame.
Five: Pop the top of the dryer open and remove the one 5/16" hex head screw that holds the top of the heating element strap to the frame.
Six: Go to the back of the dryer and remove the two leads from the thermostat that is mounted to the heating element casing. CAUTION: Be careful to note the position of the wires and be certain that you reattach the correct wire to the correct lead.
Seven: Lift the heating element case up about 1/2" to disengage the hooks at the bottom that hold it in place.Then pull the bottom of the heating toward you slightly while sliding it down. This will allow you to remove the heating element and casing.
Eight: Remove the heating element from the casing and insert the replacement heating element.

Reverse the above process to reassemble.
This entire process only takes about 20 minutes.

An additional note: Be certain that you pay careful attention to the positioning of the strap that holds the top of the heating element case to the dryer frame. If you install it incorrectly, the heating element case can fall away from the back of the drum assembly.
