Understanding the Problem
Brief overview: The Samsung model DV52J8700 (check the nameplate on the dryer to confirm exact model variant) can experience common dryer issues: no heat, not tumbling, loud noises, or door/error faults. Below are clear, practical diagnostics and repair steps for each major symptom so you can find and fix the problem. Always confirm whether your exact unit is gas or electric on the rating plate — some steps differ. 1) Dryer won't heat (electric or gas): a) Safety first: Unplug the dryer (or shut off power at the breaker). If gas, shut off the gas supply too. Wait for components to cool. b) Verify basic: For electric, confirm a 240V supply at the dryer terminal block (use a multimeter). For gas, confirm the gas supply is turned on and other gas appliances work. c) Check lint & venting: Remove lint trap, clean lint housing and exhaust vent. Restricted exhaust can look like a heating issue. d) Electric-specific checks (with power disconnected): - Inspect the heating element for visible breaks and test continuity with a multimeter. If open, replace heating element assembly. - Test the thermal fuse (on the blower housing or near heating assembly) for continuity. If blown (open), replace the thermal fuse. A blown thermal fuse often means a venting/overheat problem — clear vent before replacing. - Test high-limit thermostat(s) and cycling thermostat for continuity; replace if open. - Check the dryer timer or control board outputs for voltage to the element when running. e) Gas-specific checks: - With panel removed, run a cycle and observe the igniter. If the igniter glows but gas valves don’t open, the gas valve coils may be bad. - If igniter doesn't glow, test for power to igniter and continuity of igniter element; replace if open. - Check flame sensor and thermal cutouts; test continuity and replace if faulty. f) After replacing parts, reassemble, restore power/gas, and run a test load. 2) Dryer doesn't tumble or drum won't spin: a) Safety: Unplug or disconnect power. b) Check door switch: If the dryer thinks the door is open, it won't run. Test door switch for continuity; replace if faulty. c) Inspect drive belt: Remove the front panel (or access per manual), check belt for breakage or slipping. Replace if broken or glazed. d) Check motor: If belt is good but motor hums and won't start, test motor windings for continuity and the start components (centrifugal switch or start relay). Replace motor assembly if failed. e) Check idler pulley and drum rollers: Worn bearings or seized idler can prevent rotation or cause rubbing noise. Replace worn rollers/pulley. 3) Dryer is noisy or vibrates: a) Identify noise source: run dryer empty and listen — squeal/rumble indicates bearings/rollers; thumping suggests broken support or items caught; rattling may be objects in drum or vent. b) Inspect drum rollers, rear drum bearing, idler pulley, and motor mounts. Replace worn or broken parts. c) Check and clean the blower wheel — debris or a broken blower can cause noise. 4) Door, controls, or error codes: a) If the dryer displays codes or keys don't respond, consult the service/error code list in the user manual or on the tech sheet (paper tech sheet is often behind the control panel). Typical codes: dE (door), bE (control board), etc. b) Test the door latch and switch, wiring harness, and control board connections. Replace the part that fails testing. 5) General diagnostic workflow (step-by-step): 1. Confirm model and whether gas/electric (check rating plate). 2. Record symptoms and any error codes shown. 3. Unplug power (and shut off gas if applicable). 4. Clean lint trap and fully clean the exhaust vent to rule out airflow causes. 5. Visually inspect accessible parts (drum, belt, rollers, blower, element/igniter). 6. Use a multimeter to test continuity of thermal fuse, thermostats, heating element (or igniter), motor, and door switch as applicable. 7. Replace only the failed component(s). After replacing, reassemble, restore power/gas, and test several cycles. Safety note: Always disconnect power before opening panels. For gas models, shut off the gas supply and ensure no leaks when reassembled. If you’re not comfortable testing gas components or live voltage, call a qualified technician.
Common Symptoms
No heat (or insufficient heat), dryer won't start or tumble, loud rumbling/squealing, door not latching or error codes displayed.
Common Causes
- Clogged lint trap or exhaust vent causing overheating and thermal fuse failure
- Failed heating element (electric) or igniter/gas valve coils (gas)
- Broken drive belt, worn drum rollers, or failed motor preventing tumbling

Helpful Repair Tip
To quickly confirm heating failures: after cleaning the vent, run the dryer empty and feel exhaust airflow and temperature. No or low air plus no heat points to an airflow/venting or thermal-fuse/element problem. Use a multimeter to check continuity of the thermal fuse first — it’s cheap and commonly fails when the dryer has overheated.
Frequently Asked Questions
How do I know if my DV52J8700 is a gas or electric dryer?
Check the rating plate (usually located on the door opening or back panel). It will state the power type and requirements (e.g., 240V for electric or Natural Gas / LPG for gas). If there's a flexible gas line connected to the dryer, it's a gas model. Confirm before performing gas- or electric-specific diagnostics.
The dryer runs but makes no heat — should I replace the thermal fuse first?
Not always. Start by fully cleaning the lint trap and exhaust vent (restricted airflow often causes overheating and fuse failure). Then test the thermal fuse with a multimeter; if it’s open (no continuity), it’s blown and must be replaced. But also test the heating element (electric) or igniter/gas valve system (gas), and check thermostats — replace the part(s) that fail testing. Always fix any venting issues before replacing thermal protection parts to avoid repeat failures.
