Understanding the Problem
The Samsung DV45H7000GW/A2 is a popular electric dryer that can develop typical faults over its lifetime: not heating, not tumbling, making noise, or failing to start. Many of these symptoms are caused by a handful of replaceable components—thermal fuse, heating element assembly, drum belt, door switch, idler/rollers, motor, or the electronic control board. Before replacing parts, performing simple checks (visual inspection, lint removal, and a few electrical tests) will usually identify the failed component. Because parts and part numbers can vary by manufacturing date and region, always confirm the exact replacement part by matching your dryer’s model and serial number (typically on the dryer door opening or rear panel) to the OEM parts list. This guide lists the most common replacement parts, typical symptoms caused by each, and quick ways to verify the fault so you can make a safe, cost-effective repair decision.
Common Symptoms
Dryer won’t heat but tumbles, dryer tumbles slowly or not at all, loud squealing or thumping, dryer won’t start, error codes on the display.
Common Causes
- Open thermal fuse or failed heating element causing no heat
- Broken drum belt, worn idler pulley, or seized drum roller causing no tumble or loud noise
- Failed door switch, start switch, or main control board causing no power or intermittent operation

Helpful Repair Tip
Run a dryer service diagnostic cycle (refer to the user manual) and use a multimeter to test continuity across the thermal fuse, heating element, and motor windings. If a component shows no continuity or the thermal fuse is open, that part is the likely failure.
Frequently Asked Questions
How do I find the exact part number for my DV45H7000GW/A2?
Locate the model and serial tag (usually inside the door opening or on the rear panel). Use that exact model/serial when searching parts online or contact Samsung support. Many vendors also let you enter the model number to show compatible OEM parts—always confirm compatibility before ordering.
Can I replace these parts myself or should I hire a technician?
Many dryer repairs (belt, thermal fuse, element, door switch, rollers/idler) are DIY-friendly if you’re comfortable unplugging the dryer, removing the front or rear panel, and using a multimeter. Unplug power and follow a step-by-step guide or video for your exact model. If the issue involves the main control board or motor, or if you’re uncomfortable with electrical testing, hiring a qualified appliance technician is safer and recommended.
