Keep searches simple. Use keywords, e.g. "leaking", "pump", "broken" or "fit".
Dryer made very loud squealing, screeching noise. (Sometimes Intermittent, sometimes constant)
Note: You may want to consider replacing the 2 Drum Support rollers at this time (while your in there)

1. UNPLUG YOUR DRYER FIRST.

2. Using a phillips head screw driver - Remove 2 screws that secure the dryer door hinges to the frame, Lift door very slightly to unhook hinges and pull out door with hinges attached as straight as possible, set aside. Remove the 2 plastic tabs from the opposing side of the door hinge also secured by screws.

3. Remove the front panel (panel is shaped like a football goal post) by tilting out the top ends of the front panel toward you, then lift up to remove panel from the bottom metal retaining tabs.

4. Remove the 2 hexhead screws from the 2 retaining clips (security hooks) that secure the top
of the dryer closed.

5. Systematically remove the hexhead screws from the rest of the front of "shroud" (it holds (suspends) the drum in place between the front and back of the dryer).

*** I didn't disconnect any wires, I carefully swung out each piece that had wires attached, propped up those parts vertically ensuring no strain on the attached wires. Others may want to disconnect wires to avoid breaking or damaging them.

6. Vacuum out any dust/lint that may be present.

7. Draw a quick diagram of how the underside of the belt is threaded on the idler pulley and motor pully first. Release the tension of the belt from the underside of the drum. The easiest way is to push the idler pulley arm away from the belt and slide off the belt from the idler pulley and motor pulley. Slide the drum out.

8. Remove the hexhead screw from the bottom of the idler arm. Disconnect from retaining spring.

9. You may only need to replace just the Idler Pulley Wheel. I recommend replacing as a "unit" the Idler Pulley Wheel, Idler Arm, Ring-E and Idler Shaft Washer(s) - then you can just swap out the old one for the new one.

10. Reassemble

(When reassembling the belt - place around drum first and slide drum in place. Now from the underside-place (drape) belt around the motor pulley (it will be very loose) Now push the idler pulley arm toward the motor pulley, engage the left side of the belt around the idler pulley and slowly allow idler pulley to increase its tension on the belt) You can test manually by rotating the drum by hand to ensure proper movement.)

Replaced two parts in the gas heater assembly
I removed the front panel of the dryer by removing the 2 screw that secure it at the bottom and pulling upward to disconnect the cover at the top. I then removed the two screws that hold the metal cover that secures the 2 elements in place. I disconnected the wire plugs from the 2 elements, removed the 2 elements and replaced them with the new parts making sure to place them in the same positions as before. I then replaced the housing cover and tightened the screws. Then I replaced the front cover of the dryer.

Dryer wouldn't heat
I removed the front of the dryer by removing the two screws on the bottom of the front panel, disconnected the door switch wires. I removed the connectors from the coils on the gas valve, the heat sensor and the igniter. Loosened the gas line at the valve. I removed the screw holding the gas valve and burner assembly and removed the assembly from the dryer. Remover the screw holding the burner to the valve, and removed the igniter. Replaced the burned and reconnected what I had removed. The reason the burner didn't light was due to the gas deflectors being burned off of the burner, If the igniter, sensor, and coils check out OK , check the front of the burned to besure it is deflecting gas to the igniter

Heat Would Not Come On
After replacing all the other fuses and sensors I finally replaced the Radiant Flame Sensor and it is working perfectly.

After replacing the other parts and the heat still not coming on I read somewhere that the Radiant Flame Sensor is a normal closed circuit and when I checked with a meter it was open. I would have saved a lot of time and money if I had read that earlier.

Temperature setting not working
Took off back cover, thermostat was easily identified because of photos I've seen on website. Took 2 connectors off, removed 2 screws and removed old thermostat. That was pretty much it!

NOTE: Replacement thermostat 694674 has an adjustable temperature range setting that MUST be manually set prior to installing! You need to use the enclosed chart to find your original part# and make sure the setting is matched. My original part# 341146 had a "D" setting so I had to change but very easy to do.

drum support roller was squeaking
My 11 year old grandson and I did the repair together. He had a blast and I did too. First we removed a bunch of screws that got us no closer to getting the machine apart than when we started. Then I remembered from the last time I had the machine apart that there are two screws just below the door, angled as not to be visable unless you know where to look. Once we removed those the from came off. We removed the wires for the door light and heat sensor, remembering the order of the wires for later reinstallation. Then we undid the bolts holding down the top. Once the top was removed we took off the belt and removed the drum. We used the retainer pliers to remove the retainer ring from the first roller. We removed the roller and also the shaft as this roller was the noise maker and the shaft was not in reusable condition. We installed a new shaft, roller washer, roller, another roller washer and then the retainer ring. We repeated the same process on the other roller, although we did not replace the shaft as it was in good condition. It turned out I did not need to order the shaft washers as the rollers came with washers. Oh well, its not a good job unless you have parts left over when you are done. Once we replaced the rollers we commenced reinstallation. But first we had to google for diagram of the proper belt installation, which we found and that got the drum and belt installed properly. Thankd god for the internet. Once we had the drum installed we put the machine back together in the opposite order we took it apart. An operational test showed we did the job right, no more squeaking. The only injury was my grandson cut his thumb right after I gave him the speech about watching where your hand is going to end up when that bolt breaks free. It broke loose and into the metal bracket went his thumb. Oh well it was a good lesson and it was not a bad cut. All in all a good repair.

The dryer was not fully drying
After replaceing several parts including the thermostats the last part I replaced the coils were the defective part. I originally metered out the themostats and they appeared to be okay but since this was my first time I thought I might have been mistaken. It turns out the last part I thought it could be was the part that was defective. I will say that it is very simple to replace any of the parts involved. The hardest part was trying to open the dryer itself. But after having to do it 3 times, I'm now a pro. I also replaced the drum belt and since I had it open I also replaced the belf idler with a newer modified idler rolller.

Putting the belt back on is easy, but it helps to view the video or a picture to understand how the belt goes around it.

Gas Dryer would heat for one heating cycle but no gas afterward. Ignitor would glow.
Checked four thermocouples all showed continuity with my multimeter so they were all good. I'd read that the coils commonly went out and that these were the symptoms. Hey, it's very simple in there. Not much else could be wrong. I had a Maytag repairman come out. At first he said the problem was a blocked vent. I knew he was wrong. Then he said one of the thermocouples went out. It was $80 for him to come out. It turned out that his second diagnosis was wrong too. To repair the dryer by Maytag would have cost me $240. I gave him $80 and bought the coils for $37. They are EXTREMELY easy to replace: two screws held a bracket that held two coils. With the bracket off, I took off the old coils and slid on the new ones.
