How to Replace 312959 Dryer Drum Drive Belt on Maytag and Whirlpool Dryers — Step-by-Step

Your Maytag dryer just stopped mid-cycle. The motor's running, you can hear it humming away, but the drum isn't turning at all. Or maybe it's making a screeching sound that wasn't there last week. Nine times out of ten, you're looking at a failed drum belt — specifically the 312959, which fits most Maytag, Whirlpool, and Jenn-Air dryers built in the last couple decades.

The good news? This is one of the most common dryer repairs, and you can knock it out in under an hour with basic tools. The belt itself wears down and cracks over time from constant friction and heat cycles. You'll know it's gone when the drum won't spin, or you're hearing loud squealing noises during operation.

What You Need Before Starting

Gather these tools before you pop open that dryer panel:

• Nutdriver set (1/4" is most common)
• Phillips and flathead screwdrivers
• Socket set (for some models)
• Putty knife or panel tool (optional but helpful)
• Work gloves

Estimated repair time: 30-60 minutes
Difficulty level: Moderate

This repair works on dozens of models including the Maytag DE106, DE107, DE110, LSE1000, LSE2700W, and Jenn-Air LSE7804ACE series. Check your model number on the inside door frame or back panel to confirm compatibility.

Safety First

Unplug the dryer completely before starting. If it's a gas model, also shut off the gas supply valve. Even with the power off, some components can stay hot for 20-30 minutes after the last cycle, so give it time to cool down. Clear yourself at least three feet of working space around the dryer — you'll need room to maneuver the drum and access the belt routing path around the motor pulley.

Step 1: Remove the Front Panel or Top Access Panel

Most Maytag and Whirlpool dryers give you two ways in: through the front panel or by lifting the top. For front-loaders like the LDE series, you'll remove the lint screen housing first — pull out the lint trap, then remove the two screws hidden underneath it. Use your putty knife to release the spring clips along the top edge of the front panel, then lift it up and off. For top-access models, slide a putty knife under the top edge about 3 inches from each corner to pop the clips, then tilt the top back against the wall.

Step 2: Support the Drum and Remove the Old Belt

Here's where it gets interesting. The drum is heavy — about 20-30 pounds depending on the model — and it's only held in place by that belt wrapped around it. Reach underneath and locate the idler pulley (it's spring-loaded) near the motor. Push the idler pulley to release tension, then slip the old belt off the motor pulley. If your belt already snapped, this step's done for you. Let the drum rest on the front support rollers while you prep the new belt.

Step 3: Position the New 312959 Belt Around the Drum

Take your new belt and wrap it around the drum with the ribbed side facing in, touching the drum surface. The flat side should face out. This matters — installing it backwards will cause premature wear and that squealing noise you're trying to eliminate. The belt should sit in the center of the drum, not riding up against the edges. On models like the Maytag DE810 or LSE2700W, there's usually a slight indentation on the drum that shows you exactly where the belt tracks.

Step 4: Thread the Belt Around the Motor and Idler Pulleys

This is the tricky part, but it's doable. Reach through the opening and loop the belt around the motor pulley first — it's the larger pulley at the bottom. Then wrap it around the spring-loaded idler pulley (the smaller one). You'll need to pull the idler toward you to create slack while you slip the belt over it. The correct routing forms a figure-8 pattern. If you're not sure, snap a photo of the old belt before you remove it, or check the diagram that's usually printed on the inside of the panel you just removed.

Step 5: Test the Drum Rotation and Reassemble

Before you button everything back up, reach in and spin the drum by hand a few full rotations. It should turn smoothly with consistent resistance — no binding, no slipping off the pulleys. If it feels lumpy or catches at certain points, the belt probably isn't seated correctly on one of the pulleys. Fix that now, because you don't want to reassemble everything twice.

Once you're confident it's right, reverse your disassembly steps. Replace the front panel or close the top, reinstall any screws you removed, plug the dryer back in, and run a 5-minute test cycle with nothing inside.

Testing After Installation

Run an empty test cycle for about 5 minutes. Listen for unusual noises — you might hear a slight squeak for the first few minutes as the new belt seats itself, but it should quiet down quickly. The drum should spin consistently without jerking or stopping. Check that the belt isn't rubbing against anything it shouldn't, and that there are no marks being left on the drum. If you notice black streaks on clothes during the first load, the belt might be installed backwards or contaminated with oil — in that case, pull it back off and clean both the belt and drum with rubbing alcohol.

Frequently Asked Questions

How do I know if my dryer belt is broken or just loose?

If the belt's broken, the drum won't turn at all even though you hear the motor running. If it's just loose or worn, you'll hear squealing or thumping sounds, and the drum might turn intermittently or very slowly. You might also notice black marks on your clothes from belt dust. Pop open the panel and visually inspect it — you're looking for cracks, fraying, glazing, or obvious breaks.

Will this 312959 belt fit my specific Maytag or Whirlpool model?

This belt fits a huge range of models including Maytag DE series (DE106, DE107, DE110, DE312, DE412, DE810), LSE series (LSE1000, LSE2700W), LDE series (LDE5914ACL, LDE7304ACE, LDE8506ACE), and many Jenn-Air models like LSE7804ACE. Check the model number on your dryer's data plate — it's usually inside the door frame or on the back panel. The 312959 replaces part numbers WPY312959, Y312959, AP6024192, and 314774.

Why does my new belt squeak for the first few loads?

A slight squeak during the first 2-3 cycles is completely normal as the new belt material seats into the pulleys and drum. It should disappear within an hour of total run time. If it continues past that, check your belt routing — it might be rubbing against a panel edge or installed with the wrong side facing the drum. Also make sure the idler pulley spins freely and isn't gunked up with lint.
