What do the d80, d90 and d95 codes on my LG dryer mean?

They are Flow Sense warnings that the exhaust vent is restricted, with the higher numbers indicating more blockage. The dryer can still run, but it works harder and dries slower. Clean the lint path and the full vent run to the outside, and have the vent inspected if the warning keeps returning.

The dryer in our University City rental stopped heating overnight. What usually causes that?

A blown thermal fuse is a frequent cause, and it often blows because the vent or lint path is restricted. A failed heating element or, on gas models, an igniter can also be to blame. Report it to your landlord so a technician can test it and check the vent.

Who cleans the dryer vent in a University City apartment?

In most apartment buildings, vent cleaning is handled by the property owner or management. Tenants should keep the lint screen clean and report slow drying early. When we repair the dryer, we tell the manager if the vent is restricting airflow.

LG Dryers: What We Check First

LG dryers are not direct-drive like LG washers. They use a conventional belt around the drum, driven by a motor that also powers the blower, with rear rollers and a front bearing or slides supporting the drum. Electric units heat with an element; gas models use an igniter, flame sensor and valve coils. Many LG dryers add a moisture sensor, steam features and a heat pump on some newer models, plus Flow Sense, which watches the exhaust and warns when airflow is restricted.

Exhaust restriction triggering d80 to d95 flow sense warnings
Thermistor open or shorted, shown as tE1 or tE2 errors
Heating element or thermal fuse failure, dryer tumbling cold
Worn idler pulley, rollers or snapped belt on the drum drive

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our LG dryer repair guide.

Lint, Long Cycles and Lease Turnover

Dryers in University City's student rentals work as hard as the washers beside them, and lint builds up fast when several people share one machine and few of them clean the screen. A clogged screen or vent stretches drying time, overheats the cabinet and eventually blows the thermal fuse, a common reason a dryer suddenly stops heating.

Apartment complexes around campus and the light rail stations usually supply stacked or compact electric dryers, while houses in Highland Creek and similar neighborhoods have full-size gas or electric units with vents running through an exterior wall. Each setup needs its vent path checked as part of the diagnosis, since replacing a fuse without fixing the airflow only buys time.

Clean the screen before every load and check that the exterior flap opens while the dryer runs. Tenants should report problems to the landlord. We test the fuse, element or igniter, belt and rollers, and explain the cost first. If a gas dryer smells of gas, leave and call the gas utility or 911.
