Motor buzzed and dryer drum would not spin when pressing start

  • Difficulty: Easy
  • Time to Complete: More than 2 hours

From the first time the motor buzzed (but dryer tumbler then started to turn), 2 weeks elapsed for the dryer drum to stop turning altogether. If this occurs, DO NOT continue to push the start button because the motor armature wiring will heat up and the insulation will begin to melt and smell - a SAFETY HAZARD. Unplug dryer and lockout/tagout as appropriate.

Through basic troubleshooting, discovered the motor had seized up. Since the unit was about 10 years old and it had to be disassembled for replacement, the decision was made to replace "likely to fail mechanical components including motor, belt, both rear drum rollers/shafts, idler arm pulley/assembly/wheel, associated washers, snap rings and both front glides. Reviewed the PartSelect website and drawings, ordered the parts and they delivered on time. Buy the correct sized snap rings at a local hardware, they're much less expensive. Also once inside your dryer, you'll likely find alot of lint to vacuum out...have fun.

I went online and Googled several resources that showed how to remove the front dryer panels, as well as PartSelect repair stories. From that point on, I took photos as I was disassembling so I would know how to put it back together. Utilize pictures or whatever system you prefer to keep track of taking something apart and putting it back together.

Remove the dryer door, then the front panel Disconnect wires to the light, dryness sensor and door switch. Note belt and pulley configuration that is near the motor-this will help you later when reinstalling the belt. Also note if the ribbed side or the flat side of the belt is against the outer drum wall. Remove the door shroud.

Slip the belt off the idler pulley wheel. Remove front drum support, then dryer drum Note which end of the dryer drum is the front and the orientation of the glides on the drum support. Discard old belt. Drill out and remove the old front glide supports, then install/rivet the new glides.

Remove both old rear drum rollers/shafts, washers, etc. The rear drum roller shafts are secured to a back bracket by a hex nut....feel around you'll figure it out. Replace new roller shafts. Lightly grease using a high quality silicon grease, then replace new washers, roller, snap ring, etc

Carefully unplug wiring harness on motor, there are fragile clips on each end. Don't forget a separate ground wire from the harness is attached to the motor mount bracket. Carefully release tension on the idler arm spring. Using the correct size nut driver, remove three screws (on this model) then take out the motor/idler arm assembly. Remove the old idler arm/pulley assembly. Remove the motor mount clips on each end of the mount (I used a wide blade screwdriver). Remove and replace the motor. Motor configurations changed after Whirlpool bought Maytag, so orient it correctly insuring mounting gasket "nubs" on each end of the motor correspond to the cutouts on the motor mount. Reinstall the motor mount clips. Replace the new idler arm assembly/pulley wheel; grease moving parts with high quality wheel bearing grease. Replace motor/mount bracket assembly back into the dryer. Replace ground wire to motor mount bracket and plug wiring harness back in. Reinstall idler arm spring.

Place belt back on the dryer drum and move into place on rear rollers. Reinstall front drum support. Dryer drum should turn relatively easy. Insure belt is oriented on the drum correctly before connecting belt to motor shaft end and idler arm wheel pulley (the picture you took comes in handy here).

Reinstall the rest of the parts in reverse.

Start Switch Won't Start Dryer

My wife and I had put up with this silly switch for months where we would continually pull and pull on the switch which used to take only one pull. I found PartSelect on line and chased down the part number I needed. Unfortunately, I misread the correct part number which was different for different serial numbers within the same model number. PartSelect solved this by shipping me the correct one after I discovered my mistake (the part originally sent would now start the dryer as it was supposed to but the timer didn't advance). Anyway, I had reviewed the other "installation instructions" available. It was slightly unclear to me, from reading the other descriptions, of how to remove the timer knob. The knob is in three (3) parts. To remove it, take a pocket knife or other very thin blade and slip under the silver cap and gently pry it off (it's held by four plastic studs which engage into the middle portion of the knob). Once the silver cap is off, remove the middle portion and the inner white portion by lifting straight off. Then, remove the three #10 star screws at the top of the control panel. The control panel then pivots toward you and you can lift it out of the frame to make access to the timer even easier. Next, gently remove the cable harness on the left side of the timer control assembly by depressing the tab in the middle of the connection piece and rocking gently back and forth (it is fairly snug) until you have disconnected the cable. Next, depress the plastic tab on the left side of the timer assembly and gently slide the whole timer assembly to the left (it has a plastic tab on each of the other three sides that slide under plastic holders). Insert the new timer control assembly and simply reverse all of the steps listed above taking care that the plastic feet on the new timer control assembly are engaged under the receiving plastic keepers. This is a really easy repair and took me less than 15 minutes to complete.

The door had always opened with the wrong swing and it wasn't til I needed to repair this that I noticed you could change the swing. I changed the swing of the door and then noticed that the clip was included on both sides so i did not need to repair the catch. I still have the part so when it breaks again, I can just pop it in.

FIRST unplug dryer from electrical source, CAUTION, the top of this dryer does not open with clips, do not pry on top to open! On the front of the dryer look under the lower panel, and find two screws, one on the left side, and one on the right, remove these screws, and pull slightly down on panel to remove. Behind this panel find two screws holding the door panel, one on the left, and one on the right, remove the left, and support the door panel while removing the right side. Gently pull the bottom of door panel outward, and the clips on top of door panel will unhinge from top, carefully rotate left side of door panel to floor, and note the wire connections on switch, and orientation of switch, then unplug wires, and move door panel to a comfortable working positon. Door must be open to remove switch, then depress the two plastic retaining keepers on each side of switch, and push switch through toward door. Replace with new switch, reconnect the wires, and reassymble in reverse order. Remember, door assymbly must be inserted in dryer top at an angle, and then bottom rotated downward, and bottom panel nylon guildes inserted into door panel bottom.

First, I read reviews on this forum. Great help! I was betting, from previous reviews, that it was a drum roller. I took everything apart prior to ordering any parts. Sure enough, one drum roller was seized on the roller shaft. Decided to replace all rotating parts (rollers,shafts, belt, idler pulley) while everything was apart. I also took the opportunity to clean out all of the lint (there was a lot) from the motor and intake.
Parts were on my doorstep in two days. The dryer is like brand new. I could do this job again in less than an hour. This was money and time well spent.
