LG Dryer Repair in South Florida
LG dryer not heating, taking two cycles, or showing a flow-sense code? Same day when a slot is open. Fixed price before any work begins.
How LG builds these
LG dryers monitor airflow and can report a restriction as a code rather than simply running longer, so a flow-sense warning gives the diagnostic a useful starting point before the machine is opened. The platform is also distinctive mechanically: the drum rides on four rollers rather than a rear bearing, the heater on electric models is a coil inside a housing fed by a 240-volt circuit through two thermostats, the gas models use a flame sensor and a pair of valve coils, and both kinds read the drum temperature through a thermistor on the blower housing that the control trusts completely.
What can fail on an LG dryer
- Restricted vent reported as a flow-sense code — A flow-sense warning points first to restricted exhaust airflow. The restriction can be in the dryer, transition duct, or building vent, so the full path is checked before a dryer part is quoted.
- Thermistor drift — The machine can read the drum as hotter than it is and cut the heat early, so loads come out damp after a full cycle even when no obvious mechanical fault is visible.
- Heating element — A genuine no-heat cause, but one that must be confirmed with a meter because restricted airflow, a thermal fuse, or control fault can create a similar complaint.
- Gas valve coils and flame sensor — A gas LG that heats for a few minutes and then runs cold has coils that open when cold and fail once warm, or a flame sensor that drops out. We watch the burner through the inspection port as the coils warm, which shows the fault directly.
- Moisture sensor bars — Clothes come out damp on a sensor cycle while a timed cycle dries them fully: the two metal bars inside the drum lip are coated with dryer-sheet residue or have a broken lead, and the control ends the cycle early. Cleaning the bars and checking their continuity is a direct test.
- Drum rollers and idler — A thump that speeds up with the drum, or a squeal that comes and goes with load, is the roller or idler system. LG rollers wear flat spots and the idler's spring and pulley wear together; they are replaced as a set with the belt, because a new belt on worn rollers lasts weeks.
- Condenser fouling on ventless and heat-pump models — In buildings that cannot run an exterior duct, lint and residue collect in a different airflow path, so the same long-dry complaint needs a different diagnostic from a conventional vented dryer.
Where we start
We check the exhaust path before a heating component, because a restriction can trigger protective parts and create the same long-dry complaint as a heat fault. After airflow, the thermistor and thermostats are read, then the element or burner, and the drive system last unless the complaint is noise, in which case the rollers and idler come first.
Diagnosis uses panel codes and SmartDiagnosis where supported, followed by airflow and electrical measurements that confirm whether the restriction is in the vent path or inside the dryer; holding the right combination of buttons at power-up enters LG's test mode, which runs the motor and heater in sequence and displays the thermistor reading so a drifted sensor shows itself without the cabinet open.
thermistors, fuses, elements, coils, sensor bars and roller kits are common service parts, but exact availability depends on the model; we identify the part first and confirm whether the repair can be completed that visit, and a roller set is quoted with the belt rather than without it, and the labour is backed for 90 days.
Frequently asked questions
My LG dryer takes two cycles to dry one load. Is it broken?
Start with the exhaust path. A restricted vent can leave the dryer heating normally while moist air cannot escape, so a load takes two cycles even though the heater is working. We check the duct path and dryer airflow before quoting a heating part.
What does a flow-sense warning on my LG mean?
It means the machine detected restricted exhaust airflow. The restriction can be inside the dryer, in the transition duct, or farther along the building vent, so the warning identifies the system to inspect rather than one specific part to replace.
Why does my LG dryer dry fine on a timed cycle but not on sensor dry?
Because the sensor cycle ends when the moisture bars inside the drum stop seeing wet fabric, and bars coated in fabric-softener residue, or with a broken lead behind the drum, read dry too early. We clean and test the bars and the wiring before anything else is changed; a timed cycle does not use them, which is why it still works.
My LG dryer thumps and the noise is getting louder.
A rhythmic thump that matches drum speed is a roller with a flat spot or a drum glide that has worn through; a squeal that changes with load is the idler pulley. We replace the rollers, idler and belt together, because they wear as a set and a new belt on a tired idler does not last.
My LG dryer runs but there is no heat at all.
A no-heat complaint can involve the heating element, thermal protection, thermostat or thermistor, depending on the model. We meter the heat circuit and check airflow before replacing a component, because a failed protective device without its cause addressed is not a complete repair.
