How do I know if my Maytag dryer heating element is bad?
If your Maytag LDG7334AAE dryer tumbles normally but produces no heat, takes much longer to dry, or trips the breaker, the heater circuit needs attention. The fastest way to confirm a failed heater is a continuity test of the dryer heating element WP307178, along with the thermal fuse and thermostats.
Common symptoms you can spot
- Dryer runs but blows room-temperature air on a heat cycle
- Clothes stay damp after a full timed cycle
- Heat starts, then stops and never returns during the cycle
- Breaker trips shortly after heat should turn on
- Burning smell or scorching (stop using the dryer and inspect airflow)
Quick checks before you test parts
- Confirm the cycle: Use a heated cycle (not Air Fluff/No Heat).
- Check airflow: Clean the lint screen; make sure the vent is not crushed or clogged.
- Gas vs. electric note: Many Maytag gas dryers do not use a traditional “heating element” for heat; they use an igniter and burner. If your LDG7334AAE is gas, “no heat” is often the igniter, flame sensor, coils, or gas valve.
How we confirm the problem (multimeter basics)
- Unplug the dryer (and shut off gas if applicable).
- Test these for continuity (closed circuit):
- Dryer thermal fuse, 243-degree f WP307473
- Operating thermostat(s) (common no-heat cause)
- Heater/heat source component (electric heater or gas ignition components)
What the results usually mean
| Test result | What it points to | Typical next step |
|---|---|---|
| No continuity through thermal fuse | Overheat event or restricted venting | Replace fuse; correct airflow issue |
| Thermostat open at room temp | Failed thermostat | Replace thermostat |
| Heat source component open | Failed heater/ignition part | Replace the failed part |
Why it matters
A dryer that “runs but won’t heat” is often protecting itself from overheating or a failed heat component. Fixing airflow and testing the heater circuit prevents repeat failures and reduces dry times.

What's the life expectancy of a Maytag dryer?
A Maytag dryer like model LDG7334AAE typically lasts 13 years with normal household use and basic upkeep. Many units run longer when airflow is kept clear and wear items are replaced before they cause overheating or extra strain.
Typical lifespan and what affects it
Most dryer life comes down to heat management, airflow, and drum support wear.
- Vent restriction (long runs, crushed flex duct, clogged hood) shortens life fastest
- Overheating can damage thermostats, fuses, and wiring
- Worn drum support parts increase friction and motor load
- Gas ignition issues can cause repeated cycling and stress on components
- Heavy loads and frequent use reduce lifespan compared to light, occasional use
Parts that commonly determine “how long it lasts”
If your LDG7334AAE is noisy, runs hot, or stops heating, these are common wear or safety parts to check.
| Symptom | Common cause | Example part for this model |
|---|---|---|
| Dryer won’t run or stops mid-cycle | Overheat protection opened | Dryer thermal fuse, 243-degree f WP307473 |
| Runs but no heat (gas model) | Ignition system problem | Gas igniter 4391996 |
| Loud thumping or squealing | Drum support wear | Dryer drum bearing kit 306508 |
| Heat starts then quits | Gas valve coil weakening | Second coil 279834 |
Maintenance that adds years (simple, high impact)
We recommend these habits to help your Maytag dryer reach or exceed its typical life.
- Clean the lint screen every load
- Vacuum lint from the lint duct and blower area periodically
- Keep the exhaust vent short, smooth, and clear to the outside
- Avoid overloading; let the drum tumble freely
- Address new noises early (rollers, bearing, seals) before they damage the drum or motor
Why it matters
A dryer is designed to run within a safe temperature range. When airflow is restricted, the dryer runs hotter and longer, which increases wear on heating components, thermostats, and drum support parts and can lead to nuisance shutdowns.

Where is the model number on a Maytag dryer?
On a Maytag dryer like model LDG7334AAE, the model number is printed on the rating label; you’ll usually find it on the door opening (cabinet frame) when you open the dryer door, or on the back of the cabinet near the top.
Most common places to check
- Open the dryer door and look around the door opening on the cabinet frame
- Check the inside edge of the door itself
- Look on the back panel near the top of the dryer
- If your dryer is stacked or in a tight closet, use a flashlight and take a photo to zoom in
What the label looks like (so you know you found the right one)
The rating label typically includes:
- Model number (example: LDG7334AAE)
- Serial number
- Gas type (for gas dryers) and electrical ratings
- Brand name (Maytag)
Why it matters
We use the exact model number to match the correct Maytag dryer parts and diagrams. Even small model-number differences can change which components fit, such as a dryer thermal fuse, 243-degree f WP307473 or a gas igniter 4391996.
Quick part examples (what model matching affects)
| Repair need | Common related part for LDG7334AAE | What it helps with |
|---|---|---|
| Dryer won’t heat | Gas igniter | Ignites the burner flame |
| Dryer overheats or won’t run | Thermal fuse | Safety cutoff if overheating occurs |
