LG Dryer Not Heating in West Hollywood — What I Found

A short case study from a recent service call in West Hollywood. The client had an LG dryer that ran a full cycle but came out with cold, wet clothes. Here is how I diagnosed it and what was actually wrong.

Problem

The client called and said the LG electric dryer would not heat. The drum turned, the cycle counted down, but the clothes came out exactly as wet as they went in. She tried running the cycle twice and got the same result. The dryer was about 6 years old, in a laundry closet in a West Hollywood condo.

Diagnosis

When I arrived, I asked a few questions first. Was the dryer ever overheating before this? Any error codes? Had the vent been cleaned recently? She said no error codes, and she could not remember when the vent was last cleaned.

I started with airflow because that is the most common hidden cause on LG electric dryers in older West Hollywood condos. The vent run from the closet went up through a wall and out the roof — about 18 feet of duct with two 90-degree turns. I checked the outdoor vent flap during a test cycle. Almost no air was coming out. The flap barely lifted.

Inside the dryer, I tested the heating element first. Continuity was fine — the element itself was good. Then I tested the thermal fuse. Blown. That was the immediate cause of the no-heat problem.

But a blown thermal fuse is never the root cause. It blows because something else made the dryer overheat. In this case, the long vent run was almost fully clogged with lint.

Cause

The actual cause was a heavily clogged vent. The dryer was overheating because the hot air could not escape. The thermal fuse blew as a safety step to protect the dryer from a fire risk. The "no heat" symptom was the result of that safety part doing its job.

Repair

I cleared the vent line as much as I could from the dryer side. Then I replaced the thermal fuse. I also checked the high-limit thermostat — it had not failed yet, but I told the client it would be next if the vent was not cleared all the way to the roof.

I recommended a full roof-to-dryer vent cleaning by a vent service before the next cycle. Without it, the thermal fuse would likely blow again within weeks.

Result

After the repair, I ran a 20-minute test cycle. The dryer heated normally and the airflow at the outdoor vent improved noticeably even after my partial clearing. The client booked a vent cleaning for the next week.

Tip

If an LG (or any) dryer suddenly stops heating in West Hollywood, especially in an older condo with a long vent run, check the vent before you blame the dryer. A clogged vent is the cause behind most "no heat" calls, and replacing the thermal fuse without clearing the vent is a temporary fix that fails again fast.

FAQ

Is a blown thermal fuse a serious problem on an LG dryer?
The fuse itself is a cheap, simple repair. But it blew for a reason — almost always poor airflow. Fixing the fuse without finding the airflow problem means it will blow again.

How often should a dryer vent be cleaned?
Once a year for a single-family home with a short vent run. Twice a year or more for long runs, multi-story vents, or stacked closet setups common in older West Hollywood buildings.

Can a clogged vent really stop the dryer from heating?
Yes, indirectly. The dryer overheats because air cannot escape. The safety parts then cut the heat to prevent a fire. The result is a dryer that runs without heat.

Should I just replace the dryer at 6 years old?
No. Six years is not old for a dryer. A thermal fuse and a vent cleaning fixes most of these calls. The dryer should run another 6 to 10 years with regular vent cleaning.
