A dryer that runs but fails to dry clothes usually suffers from a lack of heat or restricted airflow. To troubleshoot, start by checking these four common culprits:
A dryer that heats but doesn't dry clothes may indicate a dirty lint screen. If you clean out the lint but your clothes are still not drying, check if your dryer is spinning. You can follow this guide on troubleshooting a dryer that's not spinning.
The cost of replacing a dryer sensor or thermistor varies based on the model and brand, but typically ranges from $10 to $30 for the part itself.
A blown thermal fuse—a critical safety mechanism that prevents appliances like clothes dryers from overheating—typically causes two main symptoms depending on the appliance: the machine will not start at all, or it runs but fails to generate any heat.
To hard reset a dryer, power it down completely to drain the control board's capacitors. Unplug the machine or flip its dedicated circuit breaker off, wait a full 1 to 5 minutes, and then restore power. This clears minor electrical glitches and temporary error codes.
Yes, unplugging a dryer is an effective way to reset it. Doing so clears the control board’s memory, which is helpful for fixing electronic glitches, clearing error codes, and resolving minor start failures.
In most cases, you cannot reset a dryer thermal fuse; it is a single-use safety device and must be replaced if it blows. However, some gas dryers feature a high-limit thermostat with a physical reset button.
Age of the Dryer
Age is one of the strongest indicators when deciding between repair and replacement: Under 8 years old: Repairs are usually worthwhile. 8–12 years old: It depends on the repair cost and symptoms. Over 12 years old: Replacement may be more cost-effective (especially after a major failure).
No, a dryer will typically not run if the thermal fuse is blown. The thermal fuse is an essential safety mechanism; once it trips, it breaks the electrical circuit, cutting off power to the machine entirely so neither the motor nor the heating element will operate.
That said, if your clothes dryer is more than halfway through its lifespan—7 years or more—and the repair costs more than 50% of the price of a new one, you should consider replacing it. But if fixing it is less than half the cost of buying something new, a repair is probably the better option.
A dryer taking 2 hours to dry clothes is almost always caused by restricted airflow or a heating failure. The three biggest culprits are a clogged exhaust vent, a dirty lint screen, or an overloaded drum.
Cleaning your dryer’s moisture sensor takes just a few minutes. Residue from dryer sheets or fabric softeners often coats the metal strips, tricking the dryer into thinking clothes are already dry.
A bad or "blown" thermal fuse will typically cause your dryer to either not start at all or run without producing any heat. You can confirm if the fuse is defective by testing it for continuity using a multimeter.
The thermal fuse on a dryer is typically a small, flat, white safety device located at the bottom of the lint chute where it meets the blower housing. On some models, it is found directly near the heating element in the lower rear or side of the machine.
To determine if a thermal fuse is blown without a multimeter, check for the physical signs of a broken internal filament if the casing is clear, or test for electrical continuity using a simple homemade battery-and-light circuit.
Possible Causes: Faulty Heating Element: The heating element is responsible for generating heat in the dryer. If it's broken or burnt out, the dryer will run, but it won't produce heat. Thermal Fuse: The thermal fuse is a safety device that prevents the dryer from overheating.
The average cost of repairing a dryer is around $100 to $400, which will generally cover most drum issues (such as a broken belt), a faulty thermostat, or clogged vents. If you're unsure whether or not a repair is worth it, refer to the 50% rule.
Dryers typically last 10 to 13 years. However, this lifespan can be extended to 15 years—or shortened to 7—depending heavily on maintenance habits, model type, and usage frequency.
A word of caution: if someone suggests you "bypass" or skip over a blown thermal fuse, please don't! Remember, the fuse is there for your safety by keeping your dryer from getting too hot and causing fires. If it's not working, replace it before you use your dryer again.
Yes, unplugging a dryer is the standard way to perform a hard reset. It clears the control board’s memory and can resolve freezing, minor error codes, or unresponsive buttons.
Replacing a dryer thermal fuse costs between $𝟕𝟓 and $𝟏𝟓𝟎 on average if you hire a professional, or $𝟓 to $𝟐𝟎 if you buy the part and do it yourself.
