Understanding the Problem
What the drum belt is and what it fixes: The drum belt (driving belt) wraps around the dryer drum and connects it to the motor and idler pulley assembly. A worn, glazed, frayed, or broken belt will cause the drum to not turn, slip during operation (squealing or rubbing sound), or produce burning rubber smells. Replacing the OEM/genuine belt restores positive drum rotation and eliminates slipping or rubbing noises. Step-by-step diagnostic and repair instructions: 1. Confirm the symptom: Verify the drum will not turn when the dryer runs, or it turns intermittently, makes a loud squeal/grinding, or you smell burning rubber only when the motor runs. Also manually spin the drum (with power off) to check for smooth rotation and belt alignment. 2. Safety first: Unplug the dryer (or shut off the breaker). For gas dryers also shut off the gas supply valve before working. Let the dryer cool if it was recently used. 3. Access the belt: Depending on your dryer model the belt is accessed by removing the top and/or front panel. For most Maytag units: a. Remove lint screen and screws under the lint well (if present). Lift or remove the top panel. b. Remove the front panel screws and disconnect any door switch harness to fold the front panel down or remove it. 4. Inspect the belt and related parts: Look for broken belt, frayed edges, glazed or shiny spots, missing ribs (on multi-rib belts), or oil contamination. Also inspect the idler pulley, motor pulley, drum rollers/glides, and the drum seam for wear that can cut or slip the belt. 5. Remove the old belt: If the belt is intact but loose, release tension by moving the idler pulley away from the motor pulley and unwrap the belt from the drum. If the belt is broken simply remove the two pieces. Support the drum if necessary while removing the belt. 6. Replace worn components: It’s best practice to replace the idler pulley and one or two drum rollers or glides if they show wear, noise, or roughness. These parts cause premature belt wear. 7. Install the new belt (genuine/OEM recommended): Route the new belt around the drum so the ribbed side contacts the drum (follow the drum’s groove). Loop the belt under the motor pulley and around the idler pulley so the idler provides proper tension against the smooth side of the belt. Make sure the belt sits in the drum’s belt track and is centered on pulley grooves. 8. Rotate the drum by hand several times: Confirm smooth rotation and correct belt path. The drum should turn freely without binding and the belt should remain centered. 9. Reassemble the dryer: Reconnect the door switch harness, reinstall the front panel, top panel and any screws or trim. Reinsert the lint filter. 10. Test run: Reconnect power (and gas if applicable). Run a short cycle empty and listen for rubbing, squeal, or slipping. Confirm drum spins consistently and there are no unusual noises or smells. Safety note: Always disconnect electrical power before working on the dryer. If you are not comfortable with removing panels, handling internal parts, or working near the gas line (for gas dryers), hire a qualified appliance technician. Use only the correct belt size and OEM or recommended aftermarket replacements for safe and reliable operation.

Helpful Repair Tip
If the drum smells like burning rubber or you can spin the drum easily by hand (with the motor off) but it won't turn when running, the belt is the likely culprit—inspect it for breakage or glazing before replacing other parts.
Frequently Asked Questions
How do I find the correct OEM belt part number for my MGDC700VW0 dryer?
Locate the model and serial tag (usually inside the door opening or on the back panel) and use that exact model number when ordering. Many parts suppliers accept the dryer model (MGDC700VW0) and will list the correct OEM drum belt. If in doubt, request the 'drum belt for MGDC700VW0' or contact Maytag/Whirlpool support with your model/serial information.
Can I replace the dryer drum belt myself, and how long does it take?
Yes — a homeowner with basic tools and comfort removing panels can replace the belt. Typical time: 30–60 minutes. Steps include disconnecting power, removing the top/front panels, removing the old belt, fitting the new belt around the drum and pulleys, and reassembling. Replace the idler pulley and worn rollers at the same time if they show wear to prevent premature belt failure.
