Your dryer runs and tumbles but clothes come out wet. You run it again — still wet. You run it a third time. Still cold air. A dryer that won't heat is one of the most common appliance repair calls we receive in Concord, NH — and in many cases, it comes with an important safety warning most homeowners are not aware of.
Here are the 5 most common reasons gas and electric dryers stop producing heat — including the one cause that is also a serious fire hazard that kills thousands of American households every year.
Fire Safety Warning
A clogged dryer vent is the #1 cause of residential appliance fires in the United States — responsible for over 15,000 house fires and 400 injuries per year. If your dryer stopped heating AND takes multiple cycles to dry a load, have your vent inspected immediately.
The 5 Most Common Causes
1. Blown Thermal Fuse — Most Common Cause
Most Common Issue
The thermal fuse is a one-time safety device that blows permanently when the dryer overheats — cutting power to the heating element or burner. Once blown, the dryer will tumble but produce zero heat.
Critical point: The thermal fuse blows because of a root cause — almost always a clogged or restricted dryer vent. Simply replacing the fuse without clearing the vent means it will blow again within weeks. Our technicians always inspect and clear the dryer vent when replacing a thermal fuse.
Repair cost: $80–$160 for thermal fuse replacement plus vent inspection and clearing. Applies to all electric and gas dryers. We carry thermal fuses for Samsung, LG, Whirlpool, GE, Maytag, and all other major brands.
2. Clogged Dryer Vent — Fire Hazard
Fire Safety Risk
A partially clogged dryer vent restricts airflow through the dryer — causing it to overheat, which blows the thermal fuse (see above). A severely clogged vent also creates a lint buildup in the vent pipe that is highly flammable. The USPS Consumer Product Safety Commission reports dryer vent fires cause over $238 million in property damage annually.
Warning signs of a clogged vent:
- Clothes take multiple cycles to dry fully
- Dryer or laundry room feels unusually hot during operation
- Clothes come out very hot to the touch but still damp
- You cannot remember the last time you cleaned the vent duct
We offer free dryer vent inspection with every dryer repair in Concord, NH. We also offer standalone vent cleaning services if you suspect your vent is blocked.
3. Failed Heating Element (Electric Dryers)
Electric Dryer Specific
In electric dryers, the heating element is a coiled wire that glows red-hot to produce heat. Over time — typically after 8–12 years — the coil burns out and breaks. The dryer will tumble normally but produce no heat at all.
This is one of the most common electric dryer repairs. We carry heating elements for all major electric dryer brands on our service vans.
Repair cost: $100–$220 for heating element replacement. Same-day repair in most cases. We test the entire heating circuit — element, thermal fuse, cycling thermostat, and high-limit thermostat — before completing the repair to ensure all components are functioning correctly.
4. Failed Gas Valve or Igniter (Gas Dryers)
Gas Dryer Specific
In gas dryers, the heat is produced by a gas burner. The most common gas dryer no-heat failures are a failed igniter (the glowing element that lights the gas) or a failed gas valve coil (the solenoid that opens the gas valve).
With a failed igniter or gas valve: the drum tumbles normally and you can hear clicking as the igniter tries to light — but the burner never fires and no heat is produced.
Important: Gas dryer repairs require a licensed, gas-certified technician. All our technicians are certified for gas appliance work in New Hampshire.
Repair cost: $120–$240 for igniter or gas valve coil replacement. Same-day repair available. See our full dryer repair page.
5. Cycling Thermostat or High-Limit Thermostat Failure
Both Types
Dryers have two thermostats: the cycling thermostat, which cycles the heat on and off to maintain temperature, and the high-limit thermostat, which shuts off the heater if the dryer overheats. When either fails in the open position, the dryer gets no heat at all. When the cycling thermostat fails in the closed position, the dryer overheats and never shuts off heat — which will quickly blow the thermal fuse.
Repair cost: $90–$180 for thermostat replacement. Our technicians test all thermostats with a multimeter to identify the failed component precisely before replacing.

Frequently Asked Questions
A dryer that tumbles but produces zero heat has almost certainly blown its thermal fuse. This is the most common no-heat repair we perform in Concord, NH. Important: we always inspect and clear the dryer vent when replacing the fuse — because a blocked vent caused the fuse to blow in the first place.
Potentially yes. A dryer that stopped heating due to a blown thermal fuse stopped heating because of overheating — which is almost always caused by a partially clogged dryer vent. That clogged vent is a fire hazard that needs to be cleared immediately, regardless of whether you repair or replace the dryer.
Most dryer no-heat repairs cost between $80 and $240 in Concord, NH depending on the component — thermal fuse, heating element, igniter, or thermostat. We provide a flat-rate quote before starting any work.
