--- title: "Dryers" description: "LG dryers: sixty-eight dryers in the catalog, in three quite different kinds: vented electric, vented gas, and the ventless heat pump machines that condense…" url: "https://lgmiami.support/appliances/dryer/" date_modified: "2026-09-05" Appliance type: "Dryers" --- # LG dryers ### Three kinds of dryer under one badge Vented electric and vented gas machines work the way every dryer has: heat the air, tumble the load, push the moisture outside. LG’s heat pump machines do not. They run a closed loop, condense the water out of the air and collect it in a container or send it down a drain, which is why they can be installed where there is no duct at all — a great deal of Miami condo laundry. It also means the maintenance is different: there is no vent to clean and there is a condenser that must be. ### What LG publishes The thermistor set tE1 through tE6, nP for no current at the heater, dE and dE4 for the door, LE1 to LE3 with AE and CE1 across the drum motor, HS at the humidity sensor, CL for the child lock, d90 and d95 for duct blockage percentages, and drn or OE for the condensate side of a heat pump machine. There is also a blinking-LED set for dryers with no numeric display, and those combinations are on this site as their own pages.

On a vented dryer that is airflow, and the machine is protecting itself. The order is the lint screen, then the duct behind the machine, then the wall vent outside — and in this city the wall vent is the one that is blocked, because the flap seizes and the lint packs behind it. On a heat pump machine the same symptom is a full water container or a blocked condenser, which LG reports as drn or OE rather than leaving you to guess. ### It tumbles but everything comes out cold. nP is LG's code for no current at the heater, and it is the honest starting point on an electric machine: one leg of the 240-volt supply, a tripped half of a double breaker, the thermal cutoff, or the element itself. On gas it is the igniter far more often than the valve, and an igniter that glows and never lights is a different failure from one that never glows. Either way it is measured, not swapped. ### The time on the display jumps from an hour to a minute. That is the moisture sensor, not the timer. LG dryers estimate the remaining time from how wet the load still is, and two metal strips inside the drum front do the measuring. Fabric softener films them over, the machine then reads the load as dry, and the number collapses. Wipe the strips with a little rubbing alcohol on a pad. It is a two-minute job that fixes a failure that looks electronic. ### Is a heat pump dryer worth repairing? Usually yes, and more often than a vented one, because the parts that fail are serviceable rather than structural. The condenser block slides out and can be cleaned; the drain pump and its hose are a part; the compressor is the expensive answer and it is uncommon. What we will tell you plainly is when the number stops making sense against a new machine — that conversation belongs before the work, not after it. --- **[Read full article: Dryers](https://lgmiami.support/appliances/dryer/)**
