LG Dryer Repair in Houston — Complete Guide to Common Problems, Error Codes & Expert Fixes
HomeFix Appliance Repair provides dryer repair in Houston, Katy, Sugar Land, Richmond, Fulshear, Bunker Hill Village, and Memorial.
We specialize in LG appliance repair near me — washer and dryer with same-day service and warranty.
Introduction
Let’s be honest — LG dryers truly deserve to be called the “people’s dryers.”
You’ll find them everywhere across Houston — from luxury houses to small apartments.
Both gas and electric models share common issues: “my LG dryer is not heating,”
“it heats but my clothes stay damp,” or “it takes forever to finish the cycle.”
After 7 or 8 years, many begin to squeak, vibrate, or emit a burning smell.
Although these problems sound similar, the reasons behind them vary.
Below, we’ll go through the most frequent LG dryer symptoms and error codes,
the real-world causes, and diagnostic steps.
We’ll also explain why codes d80–d95 don’t always mean a clogged vent — often they indicate
a defective sensor or a failing control board.
And finally, you’ll read a true case from our Houston practice:
an LG dryer showing tE1 error where the board, not the sensor, was the culprit.
Most Common LG Dryer Symptoms
- LG dryer not heating / LG gas dryer not heating up
- Dryer not drying well / dryer not getting hot
- LG Tromm dryer not spinning / dryer not spinning
- Dryer squeaking / making banging noise
- Dryer burning smell
- LG dryer stops after 5 minutes / before clothes are dry
- Control panel not working
- Error codes: d80, d85, d90, d95, tE1, tE2, tE4, HS, PS, PF, nP, E5, Add, EE
LG Dryer Not Heating — Causes and Solutions
Symptoms: The drum tumbles normally but there’s no heat; clothes remain wet after a full cycle.
Possible causes: blown heating element, open thermal fuse, faulty thermostat or thermistor, poor voltage supply (one leg missing on 240 V line), burned gas valve coil, or a malfunctioning main board.
Poor airflow can also trigger temperature-limit shutdowns.
Professional Diagnostic Checklist
- Verify 240 V power supply – both hot legs present.
- Check heater coil and thermal fuse continuity.
- Measure thermistor resistance at room and heated temperatures (see manual specs MFL69290429).
- Inspect airflow by disconnecting vent hose; confirm strong exhaust.
- If heating components test good → suspect the main PCB command circuit.

Dryer Runs but Doesn’t Dry Well
Common causes: clogged vent line, lint filter buildup, weak blower wheel, defective humidity sensor, inaccurate thermistor, or control board logic error.
Even with normal heating, restricted airflow keeps moist air inside the drum.
- Remove vent hose and check for blockage or long runs over 25 ft.
- Clean lint filter each cycle.
- Test blower wheel for free rotation and secure fit on motor shaft.
- Check humidity sensor terminals and clean metal bars with alcohol.
- If all components pass, inspect control board for heat-relay fault.
Drum Not Spinning / Motor Hums Only
Likely reasons: broken belt, worn idler pulley, seized drum rollers or rear bearing,
failed motor start winding, door switch defect, or board relay failure.
Spin the drum manually — if stiff or noisy, mechanical parts need replacement.
Dryer Makes Noise — Squeak, Bang or Grinding Sound
Typical mechanical wear appears after years of use. Worn rollers, idler pulley, or belt cause most noises.
Also check for foreign objects (coins, pins) between drum and seal.
Replacing rollers and idler restores quiet operation. Read more in our expert dryer maintenance guide.
Burning Smell While Running
If you notice a burnt odor, stop the dryer immediately and unplug it.
Possible causes: lint ignition inside heater duct, belt rubbing metal, or overheated wiring.
Inspect the heater assembly and wiring for scorch marks, then check airflow and motor bearings.
Running with restricted ventilation is a fire hazard.
FlowSense™ Errors d80 / d85 / d90 / d95
LG FlowSense™ system monitors exhaust air pressure. When airflow drops, the dryer shows codes:
- d80 – 80 % restriction (basic warning)
- d85 – intermediate restriction (≈ 85 %)
- d90 – severe restriction (≈ 90 %)
- d95 – critical restriction (≈ 95 %)
Usually this means a blocked duct or wall vent. But our technicians often find that even after cleaning, the code returns.
Alternative root causes:
- Defective flow thermistor or temperature sensor
- Loose connector between sensor and main PCB
- Burned relay track on the control board causing false readings
In many Houston cases, persistent d85–d95 errors were traced to a faulty main board instead of poor ventilation. Always test sensors before ordering duct service.
Other LG Dryer Error Codes Explained
| Code | Description | Likely Cause / Action |
|---|---|---|
| tE1 | Temperature sensor fault (TMP1) | Thermistor out of range or board input fault |
| tE2 | Second temperature sensor (TMP2) | Same diagnostic method as tE1 |
| tE4 | Steam generator sensor fault | Replace steam module or generator assembly |
| HS | Humidity sensor error | Dirty moisture bars or bad sensor wiring |
| PS / PF / nP | Power or phase error | Check voltage, neutral and ground continuity |
| E5 | Overheat warning | Inspect vent and high-limit thermostat |
| EE | Communication error | UI-PCB or harness problem |
| Add | “Add Item” display stuck | Interface key fault or moisture on panel |
Professional Diagnostic Workflow
At HomeFix Appliance Repair we follow a structured process that mirrors LG’s factory manuals (MFL69290429 and MFL62119939) while adding field experience gained from hundreds of repairs across Houston and Katy.
- Mechanical inspection: rollers, idler pulley, belt, and blower wheel
- Sensor testing: measure resistance of thermistors and humidity sensors
- Heating element and fuse tests: check for continuity and shorts
- Airflow verification: confirm strong exhaust and no kinks in duct
- Control board logic check: trace output voltages and relay switching
Real Houston Case Study — tE1 Error Misdiagnosed
One customer in Memorial called about a repeating tE1 error. He had already replaced the temperature sensor himself, but the error returned within a day. Our technician tested the sensor — it was perfect. We then checked the main board and found that it was failing to read the thermistor signal due to a damaged input circuit. Replacing the board restored full operation.
Lesson: not every tE1 code on LG dryer means a bad sensor — sometimes the control board is to blame.

FAQ — LG Dryer Repair Questions
Why is my LG dryer not heating even though it spins?
A blown heating element, open thermal fuse, bad thermistor, or control board failure can interrupt heat supply. Only proper testing can confirm the real cause.
What does code d90 mean on my LG dryer?
It signals about 90 % airflow restriction. If vents are clean but the code remains, the flow sensor or main board is likely defective.
Can I clear a d95 error myself?
Try cleaning the entire duct from dryer to outside. If the error returns, it may be caused by a faulty thermistor or control board misreading temperature.
Does tE1 always mean the temperature sensor is bad?
Not always. In our experience, tE1 can be caused by a defective control board input, even when the thermistor tests fine.
How much does LG dryer repair cost in Houston?
Diagnostics start at $65–$89. Typical repairs range $180–$350, depending on parts (sensor, heater, board). Check our dryer repair page for details.
