Drum turns but there is no heat
The dryer starts and tumbles normally, but the air inside stays cool and clothes come out damp.
Start here: Check the breaker and outlet first, because one lost power leg is the most common reason this happens.
Dryer not heating code
Whirlpool Dryer F4E4 Code
Direct answer: A Whirlpool dryer F4E4 code usually means the dryer sees a heating problem tied to missing or incorrect power. On electric dryers, the most common cause is one leg of 240-volt power being lost, so the drum may still run but the dryer will not heat.
Most likely: Start with the house breaker, dryer outlet, and power cord connection before opening the dryer. If power is correct and airflow is not badly restricted, the next likely failures are the dryer thermal cutoff, dryer high-limit thermostat, or dryer heating element.
This code fools a lot of people because the dryer can still look half-alive. Reality check: a dryer that tumbles but stays cold often has a power-supply problem, not a bad motor. Common wrong move: replacing the heating element before checking for a tripped double breaker or a loose cord connection.
Don’t start with: Do not start by ordering a control board or guessing at gas-side parts. This code is more often a power or basic heating-circuit problem.
If the drum turns but clothes stay cold,check for full 240-volt power first.
If the code comes back after a reset,move to airflow and heating-part checks.

What the F4E4 code usually looks like in the house
Code appears right after starting a heated cycle
The dryer may begin normally, then flash the code within the first few minutes when it tries to heat.
Start here: Make sure the vent is not badly restricted, then confirm the dryer is getting full power.
Dryer heats weakly or only sometimes
Loads eventually dry, but much slower than normal, and the cabinet may feel hotter than usual.
Start here: Look for crushed venting, heavy lint buildup, or an outside hood that is stuck shut before chasing parts.
Code returns after unplugging and retrying
A quick reset clears the display for a short time, but the code comes back on the next heated cycle.
Start here: That usually means the problem is still present, so move from power checks to heating-circuit checks instead of repeating resets.
Most likely causes
1. One side of the dryer power supply is missing
An electric dryer can run the motor on partial power and still fail to heat. That is the first thing to rule out with this code.
Quick check: Reset the double breaker fully off and back on, then inspect the outlet and cord for heat marks, looseness, or a burnt smell.
2. Restricted airflow overheated the heater circuit
A plugged lint path or crushed vent can overheat the dryer and trip a thermal cutoff or high-limit device.
Quick check: Pull the dryer forward, disconnect the vent, and see whether airflow improves and the code behavior changes on a short test.
3. Failed dryer thermal cutoff or dryer high-limit thermostat
These safety parts commonly open after overheating and leave the dryer with no heat.
Quick check: If power is correct and the vent path is clear, continuity testing of the heater safety parts is the next solid check.
4. Open dryer heating element
If the heater coil is broken, the dryer will tumble with no heat and may set a heat-related fault.
Quick check: After unplugging the dryer and accessing the heater housing, inspect for a visibly broken coil and confirm with a continuity test.
Step-by-step fix
Step 1: Reset the power supply and look for obvious electrical trouble
This is the safest first check and the most common fix path. Many F4E4 complaints come down to a half-tripped breaker or a bad connection at the outlet or cord.
- Turn the dryer off.
- Go to the electrical panel and find the dryer double breaker.
- Flip the dryer breaker fully off, then fully back on. Do not just tap it toward on.
- Unplug the dryer and inspect the plug and cord ends for discoloration, melting, looseness, or a burnt odor.
- Look at the outlet face for heat damage or dark marks.
- Plug the dryer back in and run a timed dry heat cycle for a few minutes.
Next move: If the code clears and heat returns, the breaker may have been half-tripped. Keep an eye on it, because a breaker that trips again points to a supply or dryer fault that needs more attention. If the drum still runs with no heat or the code comes right back, keep going. The dryer may still be missing one power leg, or the heating circuit may be open.
What to conclude: A quick reset that changes nothing usually means this is not just a display glitch.
Stop if:
- You see melted plastic, scorched wiring, or signs of arcing at the cord or outlet.
- The breaker will not reset or trips immediately again.
- You are not comfortable around the electrical panel or dryer power connection.
Step 2: Separate a house power problem from a dryer problem
Before opening the dryer, make sure the machine is actually getting the power it needs. A running drum does not prove the heater has full voltage available.
- If you have a multimeter and know how to use it safely, verify the dryer outlet has the expected full supply voltage and each hot leg is present.
- If you do not test live voltage, pay attention to clues: drum runs, timer advances, but there is no heat at all.
- Wiggle nothing while powered. If the cord feels loose in the outlet, stop and address that connection issue first.
- If the outlet and cord look questionable, have the outlet and cord connection repaired before replacing dryer parts.
Next move: If you confirm the outlet power is wrong, you have found the problem path. Fix the supply issue first, then retest the dryer. If outlet power is correct and stable, the fault is more likely inside the dryer or caused by severe airflow restriction.
What to conclude: Good incoming power shifts the diagnosis away from the house and toward the dryer heating circuit.
Step 3: Check airflow before condemning heating parts
Poor airflow is a common reason heater safety parts fail. If you skip this, a new part can fail again fast.
- Unplug the dryer.
- Pull it forward and disconnect the vent from the back of the dryer.
- Check for crushed flex duct, heavy lint packing, bird nesting at the outside hood, or a damper that will not open.
- Clean loose lint from the dryer vent connection and the first section of venting with simple dry removal or a vacuum.
- Run the dryer briefly with the vent disconnected only long enough to compare airflow and heat behavior.
- Reconnect the vent only after the short test.
Next move: If the dryer heats better or the code stays away with the vent disconnected, the vent path is the main problem. Correct the restriction before replacing heater parts. If airflow is decent and the code remains, move on to internal heater-circuit checks.
Step 4: Test the dryer thermal cutoff, dryer high-limit thermostat, and dryer heating element
Once power and airflow are ruled out, these are the main no-heat parts that fit this code on an electric dryer.
- Unplug the dryer before opening any panels.
- Access the heater housing area based on your dryer's panel layout.
- Locate the dryer thermal cutoff and dryer high-limit thermostat on or near the heater housing.
- Remove at least one wire from each part before testing continuity so you do not read through the circuit.
- Test the dryer thermal cutoff for continuity. An open reading usually means it has failed.
- Test the dryer high-limit thermostat for continuity at room temperature. An open reading usually means it has failed or tripped permanently on this style of part assembly check path for homeowners doing replacement diagnosis only after unplugging the unit and isolating the part properly for testing contextually at room temperature conditions only if accessible and clearly identified by the wiring diagram or service sheet inside the dryer cabinet area if present without guessing parts by appearance alone because similar round thermostats can look alike across the heater circuit path on many dryers but serve different jobs in the circuit layout and should not be swapped blindly based on shape alone alone alone.
Next move: If you find an open dryer thermal cutoff, open dryer high-limit thermostat, or open dryer heating element, you have a supported repair path. Replace the failed part and correct any airflow restriction that likely caused it. If all three test good and power is correct, the problem is no longer a simple homeowner parts call. At that point, wiring damage or control-side diagnosis is more likely.
Step 5: Replace only the failed heating part, then run a full drying test
Once a part has tested bad, this is where the repair becomes worth doing. Replacing only the confirmed failed part keeps you out of guess-and-buy territory.
- Install the confirmed failed part with the dryer unplugged.
- Reconnect wires one at a time so nothing gets crossed.
- Reassemble the dryer fully before testing.
- Reconnect the vent unless you are still proving a vent restriction issue.
- Run a heated timed cycle with a medium wet load and check for steady heat, normal airflow outside, and no returning code.
- If the dryer still shows F4E4 after confirmed good power, clear venting, and replacement of a failed heater-circuit part, stop and schedule service for deeper electrical diagnosis inside the dryer.
A good result: If the dryer heats normally and finishes a load in normal time, the repair path was correct.
If not: If the code returns after a confirmed part replacement, there may be wiring damage, a connection issue, or a control problem that needs a more advanced diagnosis.
What to conclude: A successful test after part replacement confirms the fault was in the heater circuit and not just a temporary reset issue.

FAQ
What does F4E4 mean on a Whirlpool dryer?
In plain terms, it points to a heating problem often tied to missing or incorrect power on an electric dryer. The dryer may still tumble, but it will not heat properly if one side of the supply is lost.
Can a dryer run and still have a power problem?
Yes. That is very common on electric dryers. The motor can run on partial power while the heater gets nothing, which is why the drum turning does not rule out a breaker, outlet, or cord issue.
Should I replace the heating element first for an F4E4 code?
No. Check the breaker, outlet, cord condition, and vent restriction first. After that, test the dryer thermal cutoff, dryer high-limit thermostat, and dryer heating element instead of guessing.
Can a clogged vent cause this code?
Yes. Bad airflow can overheat the heater housing and open a safety part like the dryer thermal cutoff. Even if you find a failed part, fix the vent restriction too or the new part may fail again.
What if all the heating parts test good?
If outlet power is correct, airflow is clear, and the heater parts test good, the problem may be in wiring or the dryer's control side. That is the point where a service tech is usually the smarter next move.
