DVE50M7450W/A3 vent blockage test and results

Fixlume editorialSource check: October 16, 2026Samsung · dryers
The short answer

This model’s documented vent test begins with a cool dryer and an empty drum. The matched manual uses Adjust Time and Dry Level to enter the test and reports End/0 or CLg/Cg. Do not import newer C80/C90 result meanings or another model’s button combination.

Models covered

DVE50M7450W/A3 with the matching DC68-03170Z manual/panel. Confirm revision and button labels first. This is a vent test, not an internal heater test or a certification that every hidden duct condition is safe.

Before you begin
Stop for smoke, burning smells, abnormal heat or repeated breaker trips. Let the dryer cool before cleaning. Do not expose wiring, bypass interlocks or work on gas components. If gas is smelled, leave and call the utility or emergency services from a safe location.

Prerequisites and results are different

Match the model and panel before entering a test. Record the actual result; entering test mode is not a passing result.

Test sequence for the matched panel

  1. Meet the prerequisites

    Let the dryer cool, empty the drum and close the door. A hot drum can cause burns and makes this the wrong time to start the documented test. Stop for burning smells, damaged wiring or other warning signs.

  2. Enter the matching test mode

    For the verified panel, press Power, then hold Adjust Time and Dry Level together for 3 seconds. InS or In indicates entry. If the labels or response differ, stop and use the exact supplied manual rather than trying unrelated combinations.

  3. Run without interrupting the door

    Press Start/Pause. The documented test takes about 2 minutes; do not open the door during it. Record the displayed result rather than treating any ending as a pass.

  4. Act on the result

    End/0 is the normal result in this manual. CLg/Cg directs attention to exhaust restriction. Arrange safe duct correction before continued use; do not disconnect a gas exhaust indoors or clear a warning merely to finish a load.

  5. Escalate conflicting performance

    If the documented result and real drying performance disagree, provide both to service. A screening result is not proof that an internal part is good or bad.

What to record next

Match an unfamiliar test result to this model’s manual before acting on it. Newer Samsung dryers can use different codes; do not transfer their result tables or test controls to this panel.

When to stop and get help

Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
