Maytag MDG6657BWW washer/dryer Parts

Most Maytag dryers, including the Maytag MDG6657BWW, typically last 10 to 15 years with normal household use and basic maintenance. Keeping airflow strong (lint screen and venting) and fixing small wear items early usually delivers the longest service life.

• Airflow and venting: A restricted vent makes the dryer run hotter and longer.
• Load size: Chronic overloading strains the drum support system and belt.
• Heat system health (gas models): Weak ignition or cycling issues increase run time.
• Routine cleaning: Lint buildup inside the cabinet accelerates wear.
• Timely part replacement: Replacing wear parts prevents secondary damage.

• Clean the lint screen every load; replace a damaged screen such as the dryer lint filter WP33001808.
• Check and clean the exhaust duct to the outside; keep the run short and not crushed.
• If drying times increase, inspect for a clogged blower housing or a slipping belt.
• Address overheating symptoms quickly; a failed safety device like the dryer thermal fuse, 243-degree f WP307473 often points to an airflow problem.
• Follow the cleaning and care schedule in the MDG6657BWW manual.

A dryer that runs with poor airflow or worn drum support parts can overheat, take longer to dry, and wear out the motor, belt, and gas ignition components faster. Simple upkeep is the biggest factor in reaching the 10 to 15 year range.

For the Maytag MDG6657BWW dryer, the most common problem we see is no heat or no start caused by overheating from restricted airflow. A clogged lint screen or vent can overheat the dryer and trip a thermal fuse or thermostat, and it can also shorten the life of drive and blower components.

• Dryer will not start: thermal fuse blown, door switch issue, or motor problem
• Runs but no heat (gas model): ignition system or gas valve components not operating
• Takes too long to dry: vent restriction, lint buildup, or weak airflow
• Loud rumbling or thumping: worn drum support rollers or bearing surfaces
• Squealing: idler pulley wear or belt tracking issues

1. Clean the lint screen before every load.
2. Check airflow at the outside vent hood; it should be strong and steady.
3. Inspect and clean the entire vent run (especially long runs and elbows).
4. If the dryer runs but does not heat, listen for ignition attempts (clicking, brief glow, then shutdown).
5. If the drum does not turn, check for a broken belt or a seized roller.

Poor venting is the root cause behind many “mystery” dryer failures because it traps heat inside the cabinet. That extra heat can blow a thermal fuse, warp seals, and accelerate wear on the motor, belt, rollers, and blower wheel. For model-specific safety and venting guidance, follow the MDG6657BWW owner's manual.

If your Maytag dryer is not drying, the most common causes are restricted airflow (lint screen or venting), a heat system problem, or a load that is too wet or too large. For the Maytag MDG6657BWW, start with airflow checks, then confirm the dryer is heating normally using the steps in the MDG6657BWW owner's manual.

• Clean the lint screen before every load; even a thin film can reduce airflow.
• Verify strong airflow at the outside vent hood while the dryer runs.
• Make sure the vent is not crushed, kinked, or excessively long.
• Avoid overloading; clothes need room to tumble for proper drying.
• If items are dripping wet after washing, address washer spin/drain issues first.

If airflow is good but drying is still poor, these parts are frequent culprits on gas dryers like the MDG6657BWW:

• Dryer thermal fuse, 243-degree f WP307473 (opens if the dryer overheats; dryer may stop heating)
• Gas igniter 4391996 (ignites the burner; a weak igniter can prevent consistent heat)
• Holding coil 279834 (gas valve coils; can fail when hot and cause intermittent heat)
• Gas sensor WP338906 (radiant sensor; helps control burner ignition)

Poor drying is usually an airflow problem; restricted venting makes cycles longer, increases operating temperature, and can cause safety devices like the thermal fuse to open. Fixing airflow first prevents repeat failures and restores normal cycle times.

To reset a Maytag dryer like model MDG6657BWW, we power-cycle it: turn it off, unplug it (or switch the breaker off) for about 1 minute, then restore power and try a cycle again. If it still will not run, a failed safety device or airflow problem is usually the real cause.

• Turn the dryer OFF.
• Unplug the power cord (or turn the dryer breaker OFF).
• Wait 60 seconds.
• Restore power.
• Select a timed cycle and press Start.

These checks solve most “reset” complaints on gas dryers.

• Confirm the door is fully closed; a bad door switch can prevent starting.
• Check household power: the motor and controls need steady power.
• Clean the lint screen and verify strong airflow at the outside vent.
• If the dryer ran, then stopped and now will not restart, test the thermal fuse.
• If the motor hums but the drum will not turn, inspect the belt and drum support parts.

A “reset” only clears a temporary control glitch. If airflow is restricted or a safety part like a thermal fuse opens, the dryer will keep shutting down until the underlying problem (usually venting or a failing component) is fixed.

For model-specific diagnostics and wiring diagrams, follow the troubleshooting steps in the MDG6657BWW manual.
