Why Your Dryer Isn't Heating in the San Fernando Valley (And How to Fix It)

Your dryer running but producing no heat is one of the most common appliance calls in Van Nuys. The answer surprises most homeowners: it's usually not the dryer.

In most cases, a dryer that runs but doesn't heat has a clogged exhaust duct or a blown thermal fuse — not a failed heating element

A completely blocked duct restricts airflow so severely that the dryer's safety thermostat trips and shuts off the heat

This is also a fire hazard — lint-clogged dryer ducts are a leading cause of home fires in LA County

The 90-second thermal fuse test: if your dryer runs but produces zero heat and has recently overheated or shut off, the thermal fuse has likely blown

This is a $15–$30 OEM part that takes about 30 minutes to replace

All Trust Appliance Repair carries thermal fuses for all major brands on every truck

If the duct is clear and the thermal fuse tests fine, the next suspects are the heating element (electric dryers) or the gas valve coils (gas dryers)

Our technicians diagnose the actual cause before recommending any parts — we never replace parts speculatively

In Van Nuys and the San Fernando Valley, we see dryer duct blockage as a contributing factor in over 40% of dryer service calls

Older homes in Van Nuys, Reseda, and North Hollywood often have long, kinked duct runs that accumulate lint faster than modern homes

If your dryer is taking 2–3 cycles to dry a normal load, that's your first sign of a partially blocked duct — call us before it fails completely.
