Understanding the Problem
If your Samsung DV45H7000GW drum turns but clothes stay damp or never get hot, the issue is usually in the heating system or power supply rather than the motor. Common culprits include a blown thermal fuse, an open heating element, a bad high-limit thermostat, or a failed temperature sensor/thermistor. Less commonly, damaged wiring or a faulty control board can prevent heat even when the dryer appears to run normally. Because this model is an electric dryer (confirm your specific unit), diagnosing the problem is a combination of electrical checks and component continuity tests. Always disconnect power before opening the cabinet. Start with the simplest and most common fixes (thermal fuse and heating element continuity) and only move on to more complex parts like thermostats, thermistors, or the main control board if the basic checks pass.
Common Symptoms
Drum tumbles but no heat or very low heat; clothes take multiple cycles to dry; dryer trips a breaker when heat is selected; unusual hot/cold cycling during a cycle.
Common Causes
- Blown thermal fuse (most common single-point failure for no-heat condition)
- Open or shorted heating element or blown high-limit thermostat
- Faulty thermistor/temperature sensor, wiring, or control board preventing heat signal

Helpful Repair Tip
Unplug the dryer and remove the rear access panel. Use a multimeter to check continuity first on the thermal fuse and then the heating element; if either shows no continuity replace it — those are the most common, lowest-cost fixes.
Frequently Asked Questions
How do I test the thermal fuse and heating element?
Unplug the dryer. Access the thermal fuse (usually on the blower housing or exhaust duct) and the heating element (rear panel or front–top access depending on model). Set a multimeter to continuity or the lowest ohms range. Remove the component from the circuit (disconnect one wire) and place probes across the part. A good thermal fuse or heating element will show continuity (close to 0 ohms); an open reading (OL) means the part is blown and should be replaced. If the heating element shows continuity but has visible breaks or burns, replace it. Always confirm voltage at the terminal block (with power on and safely measured) to rule out supply issues before replacing parts.
Can I fix a no-heat condition myself or do I need a technician?
Many no-heat problems are DIY-friendly if you have basic tools and a multimeter: testing/replacing the thermal fuse, heating element, and thermostats are straightforward with service manuals or repair guides. However, if you are not comfortable working with electrical components, if tests indicate a failed control board, or if you suspect wiring or a 240V supply problem, hire a certified technician. Always disconnect power before working and follow safety procedures; if your dryer is gas-fueled (confirm model variant), gas-related components (igniter, gas valve) require extra caution and often a pro.
