For Why Is My Dryer Not Heating Up After Cleaning the Lint Trap?, start with "Unplug and Access the Heating Element": Unplug the dryer from the wall outlet. Remove the rear access panel (usually ¼-inch hex screws) to expose the heating element housing. Take a photo of the wiring before disconnecting anything. Stop DIY if you are uncomfortable working around 240-volt electrical components. This is listed as a moderate recovery and usually takes about 1 hour.

help1. Understand the Problem

When your dryer runs but produces no heat, it's usually due to a faulty heating element, a blown thermal fuse, or a clogged exhaust vent. The lint trap only catches surface lint; deeper blockages in the vent hose or internal ducts can cause overheating and trip safety devices. Testing these components with a multimeter will pinpoint the failure.

Best First Step

Unplug and Access the Heating Element

Unplug the dryer from the wall outlet. Remove the rear access panel (usually ¼-inch hex screws) to expose the heating element housing. Take a photo of the wiring before disconnecting anything.

See what's happening and how to try the first recovery step.

Test the Heating Element for ContinuitySet your multimeter to ohms (Ω). Touch one probe to each terminal of the heating element. A good reading is 5-30 ohms; infinite or zero ohms means the element is broken and needs replacement.

Inspect and Replace the Thermal FuseLocate the thermal fuse on the blower housing (small white plastic part with two wires). Test for continuity; if no continuity, replace the fuse with an identical rated part.

Check the Vent for Airflow BlockageWith the vent hose disconnected from the dryer, run the dryer on fluff/air-only. Place your hand near the vent outlet. If little to no air flows, the internal vent path or hose is clogged.
