Direct answer: If your Amana dryer runs but does not heat, the most common causes are a restricted vent, a missing leg of 240-volt power on an electric dryer, or a failed dryer heating part such as the thermal cutoff, high-limit thermostat, igniter, or heating element.
Most likely: Start with airflow and power. A dryer that tumbles normally but stays cool often has a clogged exhaust path or a heat circuit part that opened after overheating.
First separate two lookalikes: a dryer that is truly not heating versus a dryer that heats a little but still leaves clothes damp. If you feel no warmth at all after a few minutes, stay on this page. If it gets warm but drying is slow, airflow is still the lead suspect. Reality check: dryers often lose heat because they got too hot first. Common wrong move: replacing the heating element before checking the vent and power supply.
Don’t start with: Do not start by ordering a control board or guessing at gas valve parts. Those are less common than vent, power, and basic heat-safety parts.
The drum turns, timer runs, but clothes come out just as cold as they went in.
Start here: Start with cycle selection, lint screen, outside vent airflow, and then confirm whether the dryer is electric or gas.
You feel some heat, but loads take two or three cycles and the cabinet may feel hotter than usual.
Start here: Treat this as an airflow problem first. Check the vent path and outside hood before suspecting internal parts.
The dryer starts warm, then heat drops out and may not return until the next cycle.
Start here: Look hard at restricted airflow and heat-safety parts like the dryer thermal cutoff and dryer high-limit thermostat.
You may hear ignition attempts, or see a brief glow through the lower panel, but the drum never gets hot.
Start here: After airflow checks, focus on the dryer igniter and the gas-side heat circuit rather than electric heating element parts.
This is the most common real-world cause. Poor airflow makes the dryer run hot internally, then safety parts open or the burner cycles off too fast.
Quick check: Run a short timed cycle with the vent disconnected from the dryer only if you can do it safely and watch it closely. If heat returns and airflow at the outside hood was weak before, the vent path needs attention.
An electric dryer can still tumble on 120 volts but the heater needs full 240 volts. After a breaker issue or loose connection, you get a running dryer with no heat.
Quick check: Check for a tripped double breaker or one side half-tripped. Reset the dryer breaker fully off, then back on once.
These parts commonly fail after overheating. The dryer may run fine but the heat circuit stays open.
Quick check: If the vent was badly restricted and the dryer now has zero heat every cycle, these safety parts move near the top of the list.
Once airflow and power are ruled out, the main heat-making part is next. Electric dryers use a heating element; gas dryers rely on an igniter to light the burner.
Quick check: Electric dryer with good power and no heat points toward the dryer heating element or cutoff circuit. Gas dryer with no flame after airflow checks points toward the dryer igniter or gas-side diagnosis.
A no-heat complaint is often a no-airflow complaint in disguise, and this is the safest place to start.
Next move: If airflow improves and heat comes back, the vent restriction was likely the main problem. If airflow is weak or heat is still absent, keep going before buying parts.
What to conclude: Poor venting can cause weak heat, no heat, repeated cutoff failures, and long dry times. Fixing airflow first prevents repeat failures.
Electric and gas dryers fail differently, and this split saves time and wrong parts.
Next move: If resetting the breaker restores heat on an electric dryer, monitor it closely. A repeat trip means there is still a supply or dryer fault to solve. If the electric dryer still tumbles with no heat, or the gas dryer never lights, move to internal heat-circuit diagnosis.
What to conclude: Electric dryers need full supply voltage for heat. Gas dryers can tumble normally even when the burner never lights.
If a dryer overheated from poor airflow, replacing a failed heat-safety part without fixing the vent just sets up the same failure again.
Next move: If the dryer heats with the vent disconnected, the dryer itself may be fine and the house vent path is the real problem. If there is still no heat with the vent removed, the fault is more likely inside the dryer.
Once airflow and supply issues are ruled out, the common no-heat parts are straightforward: electric dryers usually lose the heating element or a safety device; gas dryers often lose ignition.
Next move: If you find one clearly failed part and the vent issue has been corrected, you have a solid repair path. If parts test inconclusive, wiring looks overheated, or gas ignition behavior is inconsistent, it is time for a more advanced diagnosis or service call.
This is where you finish the job without turning one bad part into a repeat failure.
A good result: If heat is steady and airflow outside is strong, the repair is likely complete.
If not: If the new part does not restore heat, stop replacing parts blindly. Recheck power supply on electric models or get a full gas ignition diagnosis on gas models.
What to conclude: A successful repair restores heat and normal airflow together. If heat returns but airflow is still weak, the vent problem is not solved yet.

Most of the time it is one of three things: restricted airflow, an electric supply problem on an electric dryer, or a failed heat part like the dryer thermal cutoff, dryer high-limit thermostat, dryer heating element, or dryer igniter.
Yes. A badly restricted vent can overheat the dryer and open a safety part, or it can make the burner or heater cycle poorly enough that the dryer seems to have no heat. That is why vent checks come first.
Yes. The drum motor can run on 120 volts while the heater needs full 240 volts. That is a classic reason an electric dryer tumbles normally but never heats.
Not automatically. Replace the part that actually tests failed. If the paired thermostat also tests bad or shows heat damage, replace it too. More important, fix the airflow problem that likely caused the failure.
Not always. A glowing igniter proves part of the ignition circuit is working, but if there is still no flame, the problem may be elsewhere in the gas ignition system. At that point, stop guessing on parts and get a more complete diagnosis.
Maybe not. If you have some heat but poor drying, airflow is usually the main issue rather than a failed heater part. Focus on the vent path first, especially if the outside hood airflow is weak.
