How do I know if my heating element is bad in my Maytag dryer?
In a Maytag MGDB850WQ0 gas dryer, “no heat” is almost never a heating element problem because this model heats with a gas burner. If the drum tumbles but there’s no heat after about 5 minutes on a heated Timed Dry cycle, focus on gas supply and burner-ignition parts first (not an electric element). See the MGDB850WQ0 owner’s manual for the 5-minute heat check.
- Confirm you selected a heated cycle (not Air Fluff or unheated).
- Run Timed Dry (heated) for 5 minutes, then open the door and feel for heat.
- Make sure the gas shutoff valve is fully open.
- Check the house fuse or breaker; a dryer can run but still have no heat if a breaker trips.
- Clean the lint screen before each load and make sure airflow is strong.
If the dryer runs but won’t heat, these parts are frequent suspects:
- Ignition failure: igniter 279311
- Gas valve coils failing when hot: dryer valve coil kit 279834
- Flame sensing issue: dryer radiant sensor WP338906
- Overheat protection open: dryer thermal fuse WP3390719
- Temperature sensing problem: dryer thermistor WP8577274
| What you notice | What it often means on a gas dryer | Good next step |
|---|---|---|
| No heat at all, never ignites | Igniter, coils, radiant sensor, thermal fuse, gas supply | Do the 5-minute heat test; then inspect ignition parts |
| Heats once, then stops heating | Gas valve coils weakening | Check/replace coils |
| Long dry times, clothes still damp | Vent restriction or weak heat | Clean venting; verify strong airflow |
Misdiagnosing “no heat” as a heating element issue can waste time and money. On the MGDB850WQ0, heat depends on safe gas ignition, proper airflow, and working safety sensors; fixing the right component restores drying performance and helps prevent overheating.

How to remove the front panel of a Maytag dryer?
On the Maytag MGDB850WQ0 gas dryer, front access typically starts by disconnecting power, removing the door (hinge screws attach to the front panel), then removing the remaining front-panel fasteners and lifting the panel off its mounting tabs/clips so you can reach the drum and blower area. Use the steps in the MGDB850WQ0 owner’s manual as your model-specific reference.
- Unplug the dryer (or switch off the breaker) before opening any panels.
- Shut off the gas supply valve if you will be working near the burner or gas valve.
- Let the dryer cool completely.
- Wear cut-resistant gloves; cabinet edges can be sharp.
- Keep screws organized by location so reassembly is straightforward.
- Open the door.
- Remove the door from the front panel: remove the bottom screw from each hinge, then loosen the remaining hinge screws and lift the door upward off the hinges (the manual shows hinge screw locations and removal order).
- Remove any remaining screws in the front panel that were behind the door/hinge area.
- Release the front panel: remove lower front screws (if present) and lift the panel up and out to disengage the top clips/tabs.
- Disconnect the door switch wiring harness (if it’s attached to the front panel) before fully separating the panel.
| Area exposed | What it’s used for | Common related parts |
|---|---|---|
| Drum support area | Squeaks, thumps, poor drum support | Dryer drum support roller WPW10314173 |
| Belt/idler area | No tumble, belt noise | Dryer idler assembly WPW10547292 |
| Lint screen housing/front duct | Airflow issues, long dry times | Lint screen and duct cleaning |
Removing the front panel the right way prevents broken clips, stripped hinge screws, and pinched door-switch wires. It also gives you safe access to wear items (rollers, idler) that commonly cause noise and tumbling problems.

What's the life expectancy of a Maytag dryer?
A Maytag dryer typically lasts 13 years. With consistent care (especially lint and vent cleaning) and timely replacement of wear parts, many Maytag gas dryers like MGDB850WQ0 reach 15 years of service.
Most dryers fail early from heat and airflow stress, not from the cabinet or drum wearing out.
- Vent restriction (long dry times, overheating)
- Lint buildup in the lint screen housing and blower area
- High-use households (multiple loads per day)
- Worn drum support parts (rollers, idler) causing strain on the motor
- Heat system wear (igniter, gas valve coils, sensors)
The MGDB850WQ0 use and care guidance emphasizes cleaning the lint screen before each load; that single habit protects airflow and temperatures. See the MGDB850WQ0 owner's manual.
- Clean the lint screen before every load
- Check airflow at the outside vent hood; strong flow helps prevent overheating
- Keep the area behind the dryer clear so the vent does not kink or crush
- If cycles run long, clean the vent run end-to-end before replacing parts
These are frequent, practical repairs that keep a gas dryer running efficiently.
| Symptom | Common cause | Example part for MGDB850WQ0 |
|---|---|---|
| Squealing, thumping | Worn drum support | Dryer drum support roller WPW10314173 |
| Runs but no heat | Weak gas valve coils | Dryer valve coil kit 279834 |
| Stops mid-cycle, no heat | Overheat protection opened | Dryer thermal fuse (model-specific match required) |
A dryer that runs hot or takes too long to dry wears out faster and can damage clothing. Good airflow and quick repairs reduce stress on the motor, drum support system, and gas burner components.
