LG Dryer D95 Error Code: Critical Duct Blockage, Heat Shut Off

Quick Answer

D95 is LG's highest duct blockage alert. The dryer cuts heat completely and tumbles without warming to protect against fire. The duct must be cleaned before the dryer is useful again.

D95 is LG's highest duct blockage alert. The dryer cuts heat completely and tumbles without warming to protect against fire. The duct must be cleaned before the dryer is useful again. In some cases the blockage is severe enough that a standard brush kit cannot clear it, and a professional dryer duct cleaning service with blower equipment is needed. Replace any flexible duct with rigid 4-inch metal duct to prevent recurrence.

What Does the D95 Code Mean?

The heating element is off. Your duct is 95% blocked and the dryer is in fire-prevention mode. This needs to be fixed immediately.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Critical lint accumulation in exhaust duct run40%

D80 or D90 ignored for multiple cycles without cleaning24%

Exterior wall vent completely blocked by debris or nesting22%

Severely crushed or fully kinked flexible duct14%

Symptoms You May Notice

D95 displayed on control panel
Dryer tumbles but produces no heat at all
Clothes remain cold and wet after a full cycle
Burning smell from lint or duct area
Exhaust airflow at exterior vent is completely absent

Can you reset a Lg dryer to clear the D95 code?

D95 cannot be cleared by power cycling the dryer. After fully cleaning the exhaust duct and restoring normal airflow, plug the dryer back in and run a complete timed dry cycle. The Flow Sense sensor will detect restored airflow and automatically clear the D95 code. If the code persists after confirmed duct cleaning, the Flow Sense sensor itself may have failed.

Frequently Asked Questions

Why is my LG dryer tumbling but not heating?

If you see D95 on the display, the dryer has intentionally shut off the heating element because the exhaust duct is 95% blocked. This is a fire safety measure. You must clean the duct completely before heat will return.

Is D95 a fire hazard?

Yes. Lint accumulation in dryer ducts is one of the leading causes of house fires according to the NFPA. D95 means lint has built up to a critical level. Stop using the dryer and clean the duct immediately.

Can I DIY a D95 duct cleaning or do I need a professional?

Most homeowners can clear D95 themselves using a dryer duct brush kit if the duct run is accessible. However, if the duct runs through walls or the blockage is so severe the brush cannot break through, a professional duct cleaning service with powered blower and vacuum equipment is the better option.

How do I prevent D80/D90/D95 from recurring?

Replace all flexible duct with rigid 4-inch metal duct, keep the total duct run under 35 ft equivalent, clean the duct at least once a year, and clean the exterior vent cap seasonally. Also clean the lint trap before every load.
