Maintenance Kit

(362)
Part #4392065
The drum support roller kit (Dryer Repair Kit) allows the dryer to tumble properly by supporting the drum cylinder. The idler pulley provides the tension required for a multi-ribbed belt. The belt attaches to the drum, idler pulley, and motor pulley. If your dryer is damaged, it may be making loud, squeaking, and/or squealing noises while the drum is turning. This is from normal wear and tear. The drum may eventually stop turning all together. This is a sign the part should be replaced. This is one complete maintenance kit. The kit includes the drum belt, drum support rollers, one idler pulley, four tri-rings, and one clip. The parts are constructed of plastic, metal, and rubber, and come in black/white/silver.

Part #WP8577274
This dryer thermistor is a genuine replacement component designed to monitor and regulate internal temperature in Whirlpool dryers. Mounted on the blower housing, it plays a critical role in controlling the heating element by adjusting resistance as temperatures rise, signaling the control board to maintain safe and efficient drying conditions. A malfunctioning thermistor can result in symptoms such as no heat, overheating, premature cycle termination, or failure to start. It may also trigger fault codes like F-22, F-23, E1, or E2. Replacing the thermistor restores proper temperature regulation, protects the appliance from damage, and improves drying performance. Installation should be performed with the dryer unplugged and may require basic tools.

In either case, you will need to remove the front panel of the dryer and the drum to access the part for repair. Once you have accessed the damaged tri ring, you will simply need to slip it off and replace it with the new one. This part is sold individually. Be sure to disconnect the power source from the dryer before you begin this repair.

If your washer shakes or vibrates loudly when it reaches its max speed, check that the leveling legs are even. To ensure that the washer is firmly on the ground using all four legs, adjust the legs so that the machine is level, and tighten the locking nuts on the legs that are threaded. Keep the washer as close to the floor as possible. Your model might have rear legs that level themselves, or it might have threaded legs all around. Make sure the rubber feet have not worn out. Replace any missing or damaged legs and feet. This replacement part is sold individually.

The sensing light comes on and pf shows up after unplugging it....
Chris Boyle Profile
Hello Garry, Thank you for your question. The "PF" error code means the dryer cycle was interrupted by a power failure, press and hold the START button to restart the dryer, and the error should go away. We hope this helps!

Broken drive belt

  • DENNIS from ALTOONA, FL
  • A Bit Difficult
  • 1- 2 hours
  • Nutdriver, Screw drivers
Grow a second set of hands. Always unplug any appliance. Remove lint screen. remove two screws (philips Head). I took a wooden shim lightly tapped w/hammer to pop front of dryer top free. Mine worked on hinges and just flipped back til it rested against the wall. Removed two 5/16 screws inside holding face on carefully raise face section off the support clips at either side on the bottom. Pull drum out (I have the large style drum commercial size [approx.). Clean the inside free of all lint (known to be fire hazard). Sling new belt around drum. Get newly grown set of hands to hold drum in place. Pinch belt to fit between tensioner, lift tensioner and place belt around motor pulley. Spin drum couple times to make certain belt isn't twisted. Reverse dismantle proccess to put back together. Replace all parts that come with kit, you'll feel better knowing you got a new dryer, almost.

Dryer door catch broken
153 of 160 people found this instruction helpful.
  • Tammy from Clute, TX
  • Really Easy
  • Less than 15 mins
  • Pliers
After a few years of slamming the dryer door (at least that is what my husband says), the catch on the dryer door broke. Using pliers (I used needle nose) squeeze the outer edges of the catch together (vertically). With it compressed, it should slide out easily. My husband had jacked with ours prior to the repair, so the broken piece i n the door was actually sideways and would not fit through the hole. Using a screwdriver, I pushed that piece into the door (it lives in the door somewhere now). I was then able to slide out the rest of the old catch. Compress the new catch and insert it into the hole in the door. Push it in until it clicks into place. DONE! Happy Drying!

Bought motor, then bought blower wheel also

couldn't get blower wheel off of the motor. really tight. rounded off the wheel's square hub while trying to hold it still as I turned the motor shaft out. No, I wasn't turning it the wrong way :) I ended up going to the back of the dryer and using the multimax to quickly cut the wheel away from the hub. I love that oscillating saw! Just for fun, I put the motor in a bench vise and got the wheel hub off (in pieces). VERY tight! Ordered new wheel, and the job was smooth sailing from there on. I am guessing that experienced repair people automatically order the motor and blower wheel at the same time(?) BTW both parts were perfect matches for the originals. Not surprised; this has always been my experience with partselect.com!
