Finding your clothes damp after a cycle can be frustrating, but the issue might not require professional help. Here’s a step-by-step guide to diagnosing and fixing your Samsung dryer to restore its heating function.
Safety First
Before starting any maintenance or repair, ensure your safety by following these precautions:
- Turn Off Power: Unplug the dryer or switch off the circuit breaker to eliminate the risk of electric shock.
- Allow Cooling: If the dryer has been used recently, give it time to cool down before working on it.
- Gas Models: If you have a gas dryer, shut off the gas supply to prevent leaks.
- Work Carefully: Avoid rushing to reduce the risk of accidents or errors.
- Proper Lighting: Ensure your workspace is well-lit for better visibility.
- Clear Work Area: Keep the area free of clutter, and ensure children and pets are kept away.
- Stay Dry: Avoid working on internal parts with wet hands and ensure the area is dry.
- Consult the Manual: Check the user manual for model-specific instructions or safety tips.
- Handle Parts Gently: Use care when removing or replacing components to avoid damage.
- Protect Your Hands: Wear insulated gloves to safeguard against sharp edges and debris.
- Caution with Wires: Avoid touching exposed wires or terminals directly. Use insulating gloves or non-conductive tools as needed.
- Document Connections: Take photos or make notes of wiring terminals or connections to simplify reassembly.
- Multimeter Use: If testing voltage, ensure you understand proper use to avoid short circuits.
How to Troubleshoot Heating Issues in Your Samsung Dryer
1. Check the Power Supply
- Ensure the dryer is plugged into a working 240-volt outlet.
- Inspect the plug and cord for signs of damage, such as fraying or burn marks. Replace if necessary.
- Check your home’s electrical panel for tripped breakers. Reset any tripped breakers. If breakers repeatedly trip, consult an electrician.
- Remove the dryer’s back panel to inspect the terminal block where the power cord connects. Replace the terminal block if damaged.
- Use a multimeter set to AC voltage (VAC) to check for proper voltage:
- Test between L1 and L2 for 240V.
- Test between L1 and Neutral and L2 and Neutral for 120V each.
- If voltage is incorrect, contact an electrician to inspect the outlet.
2. Inspect the Lint Filter
- Open the dryer door and remove the lint filter.
- Clean the filter thoroughly using a soft brush or water. Ensure it is completely dry before reinserting.
- Shine a flashlight into the lint filter compartment to check for buildup.
- Use a vacuum to remove any debris in the lint filter housing.
3. Check the Dryer Vent
- Move the dryer away from the wall and disconnect the vent hose.
- Inspect the hose for obstructions, kinks, or damage. Replace if necessary.
- Clean the vent and hose using a vacuum or vent cleaning brush.
- Check the exterior vent for blockages like leaves or bird nests. Clear away any debris.
- Reconnect the vent hose and run an air-dry cycle to confirm airflow through the outside vent.
4. Test the Thermal Fuse
- Disconnect the dryer from power.
- Remove the back panel or access the blower housing to locate the thermal fuse.
- Disconnect the wires from the fuse terminals.
- Use a multimeter set to resistance (Ω) to test the fuse:
- A reading close to 0 indicates the fuse is good.
- A reading of “OL” or infinite resistance means the fuse is blown and needs replacement.
- Refer to the manufacturer’s technical information for resistance guidelines.
5. Check the Heating Element (Electric Models)
- Unplug the dryer and remove the back or front access panel to locate the heating element.
- Look for visible damage, such as breaks or burn marks on the element.
- Disconnect the wires from the heating element terminals.
- Use a multimeter set to resistance (Ω) to test the element:
- A resistance reading between 10 and 50 Ohms indicates proper function.
- Replace the element if the reading is “OL” or 0.
6. Check the Igniter (Gas Models)
- Ensure the gas supply is turned on and the gas line is not kinked, blocked, or damaged.
- Remove the appropriate panel to access the igniter near the burner assembly.
- Inspect the igniter for cracks, breaks, or discoloration. Replace if damaged.
- Use a multimeter set to AC voltage to test the igniter:
- Place the multimeter probes on the igniter terminals.
- Start a drying cycle and check for 120V during the heating process.
- Observe the igniter. It should glow brightly if functioning correctly.
- Replace the igniter if it doesn’t light up or shows dark spots.
7. Test the Gas Valve Solenoids (Gas Models)
- Unplug the dryer and locate the solenoids on the burner assembly.
- Note the wire positions and disconnect the wires.
- Use a multimeter set to resistance (Ω) to test the solenoids:
- For the two-prong coil, a reading of 1,000-1,300 Ohms is normal.
- For the three-prong coil:
- Between prongs 1 & 2: 1,000-1,300 Ohms.
- Between prongs 1 & 3: 500-600 Ohms.
- Replace any solenoids that give readings outside these ranges.
8. Test the Cycling Thermostat
- Disconnect the dryer from power.
- Remove the back panel or access the blower housing to locate the cycling thermostat.
- Use a multimeter set to resistance (Ω) to test the bias heater terminals:
- A low resistance reading indicates proper function.
- A reading of “OL” or infinite resistance means the bias heater needs replacement.
- Disconnect the thermostat terminals and test for continuity:
- The multimeter should beep if the thermostat is functioning correctly.
- Replace the thermostat if there is no continuity.

How to Maintain Your Dryer for Optimal Performance
Proper maintenance can prevent heating problems and extend the life of your Samsung dryer. Follow these tips:
- Clean the Lint Filter: Remove lint from the filter after every cycle to maintain airflow and prevent overheating.
- Inspect and Clean Vents: Check the exhaust vent regularly for clogs and clean it at least once a year.
- Check for Obstructions: Ensure the drum and surrounding areas are free of debris or foreign objects.
- Test the Door Seal: A damaged seal can cause heat to escape, reducing efficiency.
- Service Regularly: Schedule professional inspections and servicing to ensure all components are in good working order.
When to Call a Professional
While many issues can be resolved at home, some situations require expert assistance. Consider calling a professional if:
- You’ve identified a defective part but lack the tools or expertise to replace it.
- The issue persists despite cleaning vents and checking connections.
- You notice unusual noises, burning smells, or other signs of severe damage.
- The dryer’s electrical components need to be tested and you’re not comfortable handling them.
