MGD7230HC3 Maytag Dryer - Instructions

Removed the top, removed lower front cover, removed the front, removed the belt, removed the drum and the back. Removed and replaced roller support shaft and drum roller’s. Completed all Front and rear support for drum. Replaced drum , replaced drum roller belt and replaced back, completed replacement of the top, front.

I researched causes of the noise, zeroed it down to the idler pulley. I then got the dryer schematic and took the dryer apart after disconnecting the power and the vent. i did not have to remove the drum, the idler pulley was easily accessible once the top and back panels were removed. I simply removed the drive belt from tension off the pulley, removed the old pulley and installed the new one. Once finished the dryer was running whisper quiet.

I first tried replacing the Radiant Flame Sensor, which was located in a tight space and was very difficult to access. I finally gave up and called a handyman to replace it. That didn't fix my problem. I needed a new igniter. That was easy to replace, but it's fragile and I broke the first one...

Dropped new filter in.

I searched for a replacement by entering the model number and serial number of my Kenmore elite dryer. Ordering was extremely simple and it took less than a week to arrive. It fits perfectly.

Unplugged the Dryer first. Removed the two screws from the bottom panel using a 1/4 socket and removed the panel by pulling down and out. Reached behind the blower and removed the connectors from the old thermistor and then the thermistor itself by removing the two 1/4 inch hex head screws. Replaced with new part and after screwing back in, reconnected the wires and replaced the panel. From start to finish, it took me about 20 minutes.

Looked it up on YouTube. It told me to take the front panel off. I did, changed the belt, put the panel back on and it works perfectly. The part came in the time it was supposed to and it was the correct part. Thanks.

I took off the back panel off the dryer. The idler pulley could be accessed on the bottom. It was a bit cramped but not too tough to replace.

Seemed daunting but pull the front off and the drum is basically just perched inside on some rollers. You have to pull it out to really reach in and wrap the 96”+ band around it and to motor and don’t forget to tension it with tension pulley if you don’t see that if your belt broke!
Another bonus is after 10 years I got to remove the softball size fur ball rolling in the squirrel cage fan , big help on air flow!!!

Removed the top, front cover, drum and belt. Removed the idler pulley bracket and pressed the frozen pulley from the shaft. Cleaned the shaft and applied a small dab of anti seize and replaced the pulley. Installed all parts in reverse order. Dryer works like new again.

Turn off electric to unit.
Remove lint trap.
Remove lower cover below dryer door. 1 grey clip on either side. Bend upper portion of the clip down while pulling forward on panel.
Remove 4 1/4 inch bolts that hold blower duct to fan.
Push pulley upward while removing belt.
Use a small angled pick to remove pulley lock ring.
Install new washer and pulley. I added grease to pulley shaft.
Hope this helped. Good luck

Lubricated pulley wheel which temporary reduced noise. This verified what was making noise. Looked up the part on partselect.com and ordered it. Recieved idler pulley with bracket in just a few days.
Quickly removed back panel using nut driver with drill. Slipped belt off pulley, removed one screw with plyers to released spring and removed old assembly.
Inserted new assembly, connected spring, slipped belt back on roller.
Tested before replacing back panel.
All was very quiet. Replaced back panel.
All done

Unplug unit turn off gas, remove only bottom front panel first tried radient flame sensor was not the problem it was the coils which were infront easy to acess with small screw driver remove two prong coil and replaced then the three pronged coil being sure to line them back before tigtening left off cover and watched for ignition once it turned on and ran replaced cover and done.

Remove old filter, throw it away, replace with new filter.

I removed the top first followed along with removing the side bracket that holds the circuit board. I then proceeded with removing the bottom cover and front panel. I disconnected the front panel from the control board and was able to slide the front panel upward. The door and blower housing was a bit tricky to pull out without thinking I was damaging something. I then replaced all the seals and cleaned the dryer after removing the drum and belt. I also replaced the drum support rollers. Afterwards I put everything back together and had an "E1" error and I pulled the thermostat out and wiped it down from all the lint and dryer worked perfect after that. Dryer takes the right amount of time to day clothes and no more rumbling noise. The instructions videos were VERY helpful.
