Whirlpool Dryer Not Heating: What to Check

When a Whirlpool dryer tumbles but stays cold, the cause is often simple: an air-only cycle, one of the two household breakers tripped, or a closed gas valve on a gas model. If power and gas check out and the dryer still makes no heat during a short test, a part has likely failed and it is time for a technician.

Whirlpool's own help pages start with one quick test. Pick a heated timed-dry cycle, run it empty for about 5 minutes, then open the door and feel inside. Warm air means the dryer heats but is drying slowly, which usually points to airflow. No warmth at all points to power, gas or a failed part. For the same problem on any brand, see our general guide to a dryer not heating.

Safety first

• Unplug an electric dryer, or switch off its breakers, before you pull it out from the wall or touch the cord or vent.
• Gas dryer: if you smell gas, do not flip light switches, use the dryer controls or make a call near the smell. Leave the house, then call your gas utility or 911 from outside.
• Do not open the cabinet or test parts with power on unless you are trained. Electric dryers run on 240 volts.

Checks you can do yourself

1. Make sure the cycle uses heat

Whirlpool notes that Air Only and Air/Fluff cycles never add heat. They are meant for delicates, items that shrink easily, or shoes on a drying rack. If someone left the dial or touchpad on one of these, the dryer will run cold every time.

2. Check EcoBoost

On models that have it, Whirlpool says EcoBoost is on by default for the Regular/Normal cycle. It uses slightly lower heat and can add roughly 40 minutes to a load. That is not a fault, but it can feel like weak heat. Touch ECOBOOST to turn it off when you want the fastest drying.

3. Check both breakers (electric models)

An electric Whirlpool dryer runs on its own 30-amp circuit with a fuse or breaker on each side of the line. Whirlpool explains that one side powers the drum motor and the other powers the heating element. If only the heating side trips, the drum still turns but there is no heat. Check both, and reset or replace as needed.

The dryer also needs a true 240-volt supply. If your home cannot provide it, Whirlpool recommends calling a qualified electrician. If the dryer never heated after a new install or a move, also confirm the power cord was installed as the 3-wire or 4-wire instructions describe.

4. Check the gas valve (gas models)

On a gas dryer, a closed shutoff valve lets the drum spin with no flame. The valve is open when its handle runs parallel to the gas pipe. If the dryer was just moved or installed and you are not sure the connection is right, leave the gas work to a qualified installer. Our gas dryer repair directory lists companies that handle it, and our guide to a gas dryer not heating covers the burner side in more depth.

5. Read any code on the display

Whirlpool lists a few codes that matter here:

• L2: low or no line voltage is keeping the heater off. It shows during initial installation. Check fuses and both breakers and confirm the cord installation.
• AF or F4E3: airflow is restricted, usually from a full lint screen or a clogged, crushed or kinked vent.
• F3E1: a fault with the exhaust thermistor, the sensor that reads exhaust temperature. Whirlpool suggests turning the breaker off for about a minute, back on, and starting a timed dry cycle. If the code returns, the dryer needs service.
• Other F# E# codes: the control found a fault that needs a technician.

6. Clean the lint screen and vent

Weak heat and long drying times often come from airflow, not the heater. Whirlpool says to empty the lint screen before every load and wash it with warm water and a soft brush if softener sheets leave a film. With the dryer unplugged, check the duct behind it for kinks or crushing, and make sure the outside hood flap opens freely while the dryer runs.

Whirlpool recommends rigid or semi-rigid metal duct, not plastic or foil, and cleaning the vent every one to two years or sooner if drying slows. It notes many dryers work best with a total equivalent vent length under 35 feet, but your model's installation instructions set the limit. The U.S. Fire Administration adds that you should never run a dryer without its lint filter. Our page on a clogged dryer vent covers the warning signs.

Parts a technician usually tests

If the breakers, gas supply, settings and vent all check out and the 5-minute test still shows no heat, Whirlpool's guidance is to schedule service. A technician will typically check these parts:

A thermal fuse that blew once tends to blow again if the vent problem behind it is not fixed. Our dryer thermal fuse guide explains why.

When to stop and call a pro

• The empty 5-minute test shows no heat after you have checked the cycle, breakers and gas valve.
• F3E1 or another F# E# code keeps coming back.
• AF or F4E3 returns even after you clean the lint screen and the full vent run.
• You smell burning, see scorch marks, or the cabinet gets unusually hot. Stop using the dryer.
• The problem involves the gas burner, gas valve or gas line.

You can find local technicians in our Whirlpool dryer repair directory, with city pages such as Chicago and Houston. If your dryer is still under manufacturer coverage, check that before you pay for a repair.

What a no-heat repair costs

Angi puts a typical no-heat dryer repair at about $80 to $420, depending on the part. Fixr lists heating element replacement at $150 to $350, thermostat replacement at $100 to $260, and gas igniter replacement at $100 to $250. Angi lists thermal fuse repair at $80 to $130. Most companies also charge a service call, which Angi puts at $50 to $80 and which is often waived if you go ahead with the repair. Our dryer repair cost guide covers other common repairs.

If the dryer is older and the quote is high, Angi suggests that a repair costing more than about half the price of a new dryer is usually not worth it. Our guide on how long dryers last can help you decide. Whatever you choose, keep the vent clean, since a clear vent protects the new part and lowers fire risk.
