Understanding the Problem
If your Samsung DVE52M7750VA3 runs but doesn’t produce heat, the most common culprits are the heating element assembly, the thermal fuse (thermal cutoff), or associated thermostats/thermistors. Electric dryers rely on a functioning heating element to generate heat and on thermal safety devices to cut power if the dryer overheats. A failed heating element won’t glow or heat and a blown thermal fuse will open the circuit and stop the element from receiving power. Diagnosing the true cause requires a few basic checks: confirm the dryer is getting 240V power (for electric models), verify the element and thermal fuse for continuity with a multimeter, and inspect for clogged vents or lint buildup which can cause overheating and blow thermal fuses. Replacing the failed component will usually restore heat, but you should correct any venting issues that caused the failure to prevent recurrence.
Common Symptoms
Dryer tumbles but clothes remain cold or only slightly warm; dryer trips circuit breakers or intermittently heats; burning or overheating smells; dryer runs shorter/longer cycles than normal.
Common Causes
- Open or burned heating element assembly (open coil or internal break)
- Blown thermal fuse/thermal cutoff due to overheating or blocked venting
- Faulty high-limit thermostat or cycling thermostat/thermistor preventing the element from energizing

Helpful Repair Tip
Before replacing parts, disconnect power, remove the rear or front access panel, and test the heating element and thermal fuse for continuity with a multimeter—no continuity on either usually means replacement is needed.
Frequently Asked Questions
How do I know if the thermal fuse is blown?
Power off and unplug the dryer, remove the access panel to reach the thermal fuse, then test it with a multimeter set to continuity or resistance. A good thermal fuse will show continuity (close to 0 ohms). An open reading (infinite resistance) means the fuse is blown and must be replaced. Note: thermal fuses are single-use safety devices—if blown, replace it and address any vent or overheating issues that caused it to blow.
Can I replace the heating element or thermal fuse myself, and how much will it cost?
Yes, if you’re comfortable with basic tools and safety (disconnecting power and accessing internal panels), you can replace the heating element or thermal fuse yourself. Typical parts cost: thermal fuse or thermostat — modest (often under $30), heating element assembly — higher (commonly $50–$200 depending on OEM vs aftermarket). Labor cost at a repair shop varies. Always verify the exact part numbers for your dryer’s serial/model and follow a model-specific disassembly guide or service manual.
