A restricted vent or lint buildup
When air cannot leave the dryer, it overheats and trips a safety device such as the thermal fuse or high-limit thermostat. The drum keeps turning, but the heat shuts off.

Dryer Not Heating: Causes, Safe Checks & When to Call
A dryer that spins but does not heat is a very common call. The cause is often airflow or power rather than the heating part itself, so a few simple checks can save a service call.

Common causes
What usually causes it
A blown thermal fuse
The fuse is a one-time safety part. It almost always blows because of an airflow problem, so the vent needs attention along with the part.
A half-tripped 240-volt breaker
Electric dryers use two legs of power. If one leg is lost, the motor and controls run but the heating element does not.
A failed heating element (electric)
The element can break or burn out, leaving the dryer to tumble with no heat.
Igniter or gas valve problems (gas)
A weak igniter or failing gas valve coils can keep a gas dryer from lighting the burner.
Safe checks
What you can check yourself
These steps are safe for most homeowners. If a step feels beyond your comfort level, skip it and call.
- Clean the lint screen and wash it monthly to remove the film left by dryer sheets.
- Switch the dryer breaker fully off, then back on. If it trips again, stop and call for service.
- Run the dryer and check the outside vent. You should feel strong warm airflow and see the flap open.
- Look at the flexible hose behind the dryer for crushes or kinks, and avoid overloading the drum.
Safety first. If you smell gas near a gas dryer, leave the home right away and call 911 or your gas utility from outside. Do not use phones, light switches, or flames inside. A burning smell or an exterior that is very hot is also a reason to stop using the dryer.
When to call
When it is time to call a technician
Call after the vent and power checks if the dryer still does not heat, if it blew a thermal fuse more than once, if you have a gas dryer, or if there are signs of a fire risk such as a burning smell.

Local factors
Coastal Florida factors and what technicians look for
Humidity and salt air speed up lint packing and corrosion on electrical contacts and heating elements. Long vent runs, which are common in coastal homes and condos, clog faster. Having the whole vent run cleaned, not just the lint screen, matters more where humid air is the norm.
Technician insight
Technicians stress that a blown thermal fuse almost always has an upstream airflow cause. Replacing the fuse without cleaning the vent often leads to a quick repeat failure. Half-tripped electric breakers are another frequent no-heat call that looks like a bad part but is not.
Questions
Common questions
Why does my dryer run but not get hot?
The two most common reasons are a restricted vent that tripped a safety device and an electric dryer that has lost one leg of its 240-volt power. A failed element or igniter is the next most likely cause.
Is it safe to keep using a dryer that does not heat?
A dryer that is not heating is not necessarily dangerous, but a clogged vent is a fire risk. Stop using it if you notice a burning smell or extreme external heat.
Does a dryer that is slow to dry have the same cause?
Often, yes. A restricted vent is the leading cause of both. See dryer takes forever to dry.
Next step. If the dryer still does not heat, request service and give us the model number, whether it is gas or electric, and any error code. Do not take apart energized equipment.
