Understanding the Problem
Brief explanation: A worn or broken drum belt and seized/worn drum rollers are the most common reasons a Maytag Neptune dryer (MDE5500AWQ) will make squealing/grinding noises, have a rough or binding drum spin, or stop tumbling entirely. The belt turns the drum; the rollers support the drum and allow it to spin smoothly. When rollers wear or seize the motor and belt are overloaded and fail sooner. Step-by-step diagnostic and repair steps: 1) Safety first: - Unplug the dryer from the electrical outlet. If it’s a gas dryer, turn off the gas supply and shut off the gas valve. Wear gloves and eye protection. 2) Confirm the symptom and isolate the problem: - With the dryer unplugged, open the door and manually rotate the drum. Listen and feel: rough grinding, scraping, binding or wobble indicate rollers or glides. A smooth spin with heavy resistance indicates a stretched/partially broken belt or motor/roller drag. - Remove the front lint screen and use a flashlight to inspect the visible belt for fraying, glazing or cracking. 3) Remove access panels to inspect belt, rollers and idler: - For the Neptune MDE5500AWQ you typically remove the top (release clips at the front), then the front panel and/or bulkhead. Take photos during disassembly to help reassembly. 4) Inspect rollers and idler pulley: - Spin each drum roller by hand. If there’s roughness, grinding, excessive wobble or side-to-side play, replace the roller(s). Check the idler/tensioner pulley for smooth spin and worn bearing. - Check drum support glides or felt. If worn or scored, replace them too. 5) Inspect the belt: - Look for cracks, missing ribs, glazing or a snapped belt. If the belt is stretched, replace it — a stretched belt will slip and reduce tumbling force. 6) Remove the drum and replace parts: - Remove the front bulkhead or lift the drum out (note orientation). Replace drum rollers (usually 2–3), idler pulley if worn, and the belt. - Install new rollers into their housings (ensure axle and retaining clips are seated). Fit the belt around the drum with the ribbed side facing the drum and thread it under the idler and motor pulley per original routing. 7) Reassemble and test: - Reinstall the front panel/top, reconnect power (and gas if applicable). Run the dryer empty and listen for smooth, quiet rotation. Verify normal tumbling and no rubbing or unusual noises. 8) Final checks: - Check drum alignment, felt glides, and that the belt runs centered on the drum. How to fix (practical steps): - Replace all worn rollers rather than a single one — rollers wear together and replacing one alone often leads to quick future failure. - Replace the belt while you have the dryer open; it’s inexpensive and easy to do while rollers are accessible. - Use OEM or high-quality aftermarket parts matched to model MDE5500AWQ. Safety note: Always disconnect electrical power before servicing. If you’re not comfortable working on appliances, or if the dryer is gas-equipped and you must disconnect/reconnect gas lines, hire a qualified technician to avoid electrical shock or gas leaks.

Helpful Repair Tip
To confirm bad rollers: with the belt removed spin each roller by hand. Any roughness, grinding or side-to-side play means the roller should be replaced. Also try lifting the drum at the top — excessive vertical play indicates worn rollers or bearings.
Frequently Asked Questions
How much does it cost to replace the belt and rollers on a Maytag Neptune dryer?
Parts typically run $25–$80 depending on brand and whether you buy a roller kit (rollers + belt) or individual pieces. Labor from a technician is commonly $100–$250 depending on local rates. If you do it yourself you can often finish the job in 1–2 hours with basic hand tools.
Can I keep using the dryer if I hear noise from the drum?
You should stop using the dryer if you hear loud squealing, metal-on-metal grinding, or feel the drum wobble. Continued use can damage the motor, heater assembly or drum, increasing repair cost. Unplug the unit and inspect or replace the belt, rollers and glides as needed.
