Gas vs. Electric Dryer: What's Different When It Comes to Repair?
When your dryer stops heating, the fix depends largely on whether you have a gas or electric model. Both types share many components — a drum, motor, belt, and blower — but the heating systems are fundamentally different. Understanding these differences helps you have a more informed conversation with your repair technician.
How Electric Dryers Heat
Electric dryers use one or two heating elements — coiled metal wires that glow red-hot when electricity passes through them. The most common electric dryer repairs include:
- Burned-out heating element — The most frequent cause of an electric dryer not heating. Elements wear out over time and are relatively straightforward to replace.
- Thermal fuse — A safety device that blows when the dryer overheats, usually due to a clogged vent. Once blown, it must be replaced (they’re not resettable).
- High-limit thermostat — Regulates the maximum temperature. When it fails, the element may not receive power.
How Gas Dryers Heat
Gas dryers use a burner assembly with an igniter and gas valve solenoids. The igniter glows hot enough to open the gas valve, igniting the gas to produce heat. Common gas dryer repairs include:
- Gas valve solenoids — These are the most common failure point on gas dryers. The solenoids open the gas valve when the igniter reaches the right temperature. When they fail, the igniter glows but gas never flows. The dryer tumbles without heat.
- Igniter — The flat or round igniter can crack or weaken over time. If it doesn’t glow at all, or doesn’t get hot enough to trigger the gas valve, it needs replacement.
- Flame sensor — Detects whether the burner has ignited. A faulty flame sensor can shut off gas flow prematurely.
- Thermal fuse — Same function as in electric dryers. Blows when the dryer overheats.
Cost Differences
Gas dryer repairs tend to cost slightly more than electric dryer repairs — the parts are typically more expensive and the repair requires working with gas lines, which demands additional safety precautions. However, the difference is usually modest ($50-$100 in most cases).
Safety Considerations
Gas dryers require extra safety attention. If you smell gas, turn off the dryer, open windows, and leave the area. Do not attempt to repair a gas connection yourself — always call a licensed technician.
Electric dryers run on 240V circuits, which can be lethal. Never attempt to work on the electrical components of a dryer yourself.
The Bottom Line
Whether you have a gas or electric dryer, the most important maintenance step is the same: keep your lint trap and dryer vent clean. A clogged vent is the #1 cause of dryer fires and the most common reason we see for both thermal fuse failures and overheating issues.
