What a LG dryer is like to work on
LG dryers do something no other brand does: they measure how restricted the exhaust is and report it as a percentage on the display. Most owners read D80 or D90 as an error code and call for a repair. It is not a fault at all — it is the machine telling you the duct is nearly shut, and the repair is the vent run rather than the dryer.
Model lines we service
What we open one for
D80, D90 or D95 on the display
Exhaust restriction, at 80, 90 or 95 per cent blocked. Not an error. Clear the run — the whole run, not the first three feet — and the reading falls and the cycle times come back.
Runs cool, or heats then stops
A thermistor or a heating element on the vented machines. On a heat-pump model it is a different animal: the condenser fouls with lint and drying times stretch out long before anything is reported.
Everything takes far longer than it used to, with no code at all
Airflow again, or the moisture sensor. Fabric softener films the sensor bars until wet laundry reads as dry and the cycle ends early.
Is there a code on the display?
We have written out what each LG code reports, what causes it, and whether it needs anybody at all — several of them are not faults.
LG error codesParts and what they cost
Thermistors, elements and rollers are readily available. On heat-pump models the condenser is a maintenance item rather than a part, and cleaning it usually restores the original performance.
Most dryer jobs land between $150 and $350, parts included, and the $150 minimum service call is part of that rather than on top of it.
When to call LG instead of us
LG warrants the linear compressor for ten years on most refrigerators — the part, through their own service network. If your fridge has stopped cooling, call LG before you call us. Certain 2014–2017 models were also covered by a class-action settlement with extended terms; if yours is that vintage it is worth checking whether you are inside it. We will not fit a compressor into a machine that still has coverage on it, and we will say so on the phone rather than after arriving.
Answered
- What part does D90 need?
- None. That is a measurement, not a fault: the exhaust duct is about ninety per cent restricted. Pull the machine out and check the flexible hose is not crushed against the wall, then have the full run cleared. The number drops on its own.
- Do heat-pump dryers need different servicing?
- Yes, and it is mostly the condenser. It fouls with lint, drying times creep up, and no error is ever shown. It wants cleaning on a schedule rather than when something goes wrong.
