Understanding the Problem
Brief explanation: The dryer drum belt wraps around the drum and connects to the drive motor and idler pulley. If the belt breaks, slips, or is badly glazed, the drum will not turn—clothes won't tumble and drying fails. Replacing the belt is a common homeowner repair. Step-by-step diagnostic and replacement instructions: 1) Safety first: Unplug the dryer from the electrical outlet. If you have a gas dryer, shut off the gas supply valve and disconnect power before starting. Wear gloves and safety glasses. 2) Confirm the belt is the problem: Manually try to rotate the drum. If it spins freely with no resistance or you hear slipping/burning and see a broken or glazed belt, the belt is likely at fault. (See Helpful Tip below for confirmation.) 3) Tools needed: Phillips and flathead screwdrivers, 5/16" or 1/4" nut driver (depending on screws), 7/16" or 1/2" socket or wrench for motor/idler hardware (if applicable), needle-nose pliers, flashlight, and a replacement belt. Optional: vacuum to clean lint and a helper to hold panels. 4) Remove the lint screen: Take out the lint trap and remove any screws at the lint housing (many Maytag tops have 2 screws behind the lint screen). Some models use spring clips—use a putty knife to release if required. 5) Remove the top panel: After the screws/clips are removed or released, slide the top back slightly and lift off. Set the top aside. 6) Remove the front panel: Locate and remove the screws holding the front panel to the cabinet (usually at the top corners). Open the dryer door and remove any screws along the door opening. Carefully lift the front panel off the bottom hooks. Disconnect the door switch harness if needed and set the front panel aside. 7) Remove the drum: Reach in and lift the drum slightly to clear the rear drum support. Pull the drum straight out and set it forward so you can access the belt and motor area. 8) Inspect components: Check the belt condition (frayed, glazed, broken), idler pulley (spins freely, no wobble), motor pulley, drum glides/rollers and rear drum bearing. Replace any worn parts while you're in there. 9) Remove the old belt: If the belt is broken, simply remove the pieces. If it's intact, slip it off the idler and motor pulley and pull it free from under the drum. 10) Install the new belt on the drum: Position the new belt in the drum's outer groove (ribbed side toward the drum surface unless belt orientation is specified by the manufacturer). Most Maytag belts wrap under the drum and have the ribs against the drum. 11) Reinstall the drum and route the belt: Set the drum back into the cabinet, resting it on the rear drum support. Feed the belt around the motor pulley and idler pulley. The belt should loop under the idler and go around the motor pulley last. Ensure the belt sits square in the drum groove and is not twisted. 12) Re-tension the belt: Pull the idler pulley outward to apply tension so the belt is snug. Confirm the belt has good tension by turning the drum by hand a few revolutions; it should feel firm and not slip on the motor pulley. 13) Reassemble the dryer: Reconnect the door switch harness, set the front panel back into place and secure screws. Reinstall the top panel and replace the screws/clips behind the lint screen. Reinstall the lint screen. 14) Test the dryer: Reconnect power (and gas if applicable). Run the dryer empty on a short cycle and observe drum rotation, listen for abnormal noises, and check for proper tumbling. If you hear squeal or see wobble, shut off and recheck idler and drum alignment. Safety note: Always unplug the dryer and shut off gas before starting repairs. If you are not comfortable working around electrical or gas connections, hire a qualified technician. Keep hands and tools clear of the blower and motor when testing with power applied.

Helpful Repair Tip

Frequently Asked Questions
Can I replace the dryer belt myself?
Yes. Replacing the belt on a Maytag DE412 is a common DIY repair if you are comfortable with basic tools and following the safety steps above. Unplug the dryer first, follow the step-by-step instructions, and take pictures during disassembly to help with reassembly. If you're unsure about gas connections or electrical safety, call a pro.
How long does a belt replacement take and how much does it cost?
A typical belt replacement takes 45–90 minutes for a novice DIYer (less for experienced technicians). Parts cost for the belt alone is commonly $15–$40 depending on brand; if you replace idler pulleys or rollers at the same time expect $30–$100 in parts total. Labor from a technician will add to that cost.
