A dryer that tumbles but doesn't heat is one of the most common appliance problems we see in Dallas. The drum spins, the motor runs, but your clothes come out cold and damp. The good news: it's almost always one of five parts, all of which are affordable and most of which we carry on every truck. Here's what's likely wrong and what it'll cost to fix in DFW.
1. Thermal fuse blown (most common)
The thermal fuse is a safety device that cuts power to the heating element if the dryer overheats. Once it blows, the dryer will still tumble but won't heat. The most common cause of a blown thermal fuse is a clogged dryer vent — the dryer can't exhaust hot air, so it overheats and the fuse sacrifices itself to prevent a fire.
Typical cost in DFW: $145–$200. The part is only $15–$35, but the labor involves disassembling part of the dryer. Repair time: 30 minutes. We carry thermal fuses for every major brand on every truck.
2. Heating element failed (electric dryers)
If you have an electric dryer and the heating element has burned out, the dryer will tumble but produce no heat at all. The heating element is a coil of wire that glows red hot to warm the air. Over time, the coil breaks.
Typical cost in DFW: $185–$280. The part runs $50–$120 depending on brand. Repair time: 45–60 minutes. We carry heating elements for Whirlpool, GE, Samsung, LG, and Maytag electric dryers.
3. Gas igniter weak or failed (gas dryers)
Gas dryers don't have a heating element — they have an igniter that lights the gas burner. Over time, the igniter gets weak and won't draw enough current to open the gas valve. You'll see the igniter glow, but the burner never lights.
Typical cost in DFW: $165–$240. The igniter is $35–$80. Repair time: 30–45 minutes. Less common but similar cost: gas valve coil failure, which prevents the gas valve from opening even when the igniter works.
4. High-limit thermostat tripped
The high-limit thermostat is another safety device that shuts off the burner or heating element if the dryer gets too hot. Unlike the thermal fuse, the high-limit thermostat resets when the dryer cools down — but if it's stuck open, the dryer won't heat at all.
Typical cost in DFW: $145–$210. Repair time: 30 minutes.
5. Cycling thermostat failed
The cycling thermostat regulates the dryer's temperature by turning the heat on and off. When it fails, the dryer may not heat at all, or may heat continuously (which will blow the thermal fuse eventually). This is the least common of the five causes but still worth checking.
Typical cost in DFW: $145–$220. Repair time: 30–45 minutes.
Can you diagnose a 'dryer not heating' yourself?
If you own a multimeter and are comfortable disassembling your dryer, you can test all five of these components yourself. YouTube has decent tutorials. But here's why most Dallas homeowners call us instead:
- Disassembling a dryer to access the heating element requires removing the drum — heavy and awkward.
- Testing components with a multimeter requires removing them from the circuit, which means more disassembly.
- Ordering the wrong part is easy — there are dozens of variations even within a single brand.
- If you misdiagnose, you've spent $80 on a part that wasn't the problem.
- A $30 video diagnosis will often pinpoint the issue in 15 minutes — we can tell you which part to order if you want to do the labor yourself.
Dallas-specific dryer vent advice
DFW homes, especially newer construction in Frisco, Celina, and Prosper, often have laundry rooms in the interior of the house with long dryer vent runs (sometimes 20+ feet with multiple elbows). These long runs are notorious for clogging with lint, which causes thermal fuse failures and creates a fire hazard. If your dryer vent runs more than 15 feet, we recommend professional vent cleaning annually — it'll save you $145+ in fuse replacements and dramatically reduce fire risk.
