What does Kenmore Dryer Not Heating - Causes & Fix mean?

Most often caused by blown thermal fuse from lint-blocked vents or incorrect 240V supply on electric models. Clean vents, test fuse.

How do I fix Kenmore Dryer Not Heating - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Kenmore Dryer Not Heating - Causes & Fix?

The most frequently replaced parts for Kenmore Dryer Not Heating - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Kenmore Dryer Not Heating - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Kenmore Dryer Not Heating - Causes & Fix

Kenmore Dryer Not Heating — What’s Happening

A Kenmore dryer that runs but produces no heat is a symptom, not a single fault code. The drum turns and the controls light up, but clothes stay cold or damp after a full cycle. This points to a break in the heat circuit, a power supply issue, or a safety device that has tripped due to overheating or airflow restriction.

On electric Kenmore dryers, the most common culprits are a blown thermal fuse (often from clogged vents) or missing 240V at the wall outlet. On gas models, a weak or failed igniter or bad gas valve solenoids prevent the burner from lighting. Some Kenmore models display codes like F28 or F29 for moisture sensor or thermistor faults, but a simple no-heat symptom usually means you need to test the heat circuit components one by one with a multimeter.

Most Likely Causes

Blown thermal fuse The thermal fuse sits on the blower housing or heater assembly and opens permanently when the dryer overheats, usually because lint blocks the exhaust vent or internal ductwork.
Incorrect or missing 240V supply (electric dryers) A tripped breaker, loose cord connection, or miswired outlet delivers only 120V, so the motor runs but the heating element receives no power.
Failed heating element (electric dryers) The element coil can break or short to ground over time, stopping all heat production.
Open high-limit thermostat or cycling thermostat These snap-action thermostats monitor temperature and can fail open, cutting power to the heating element or gas igniter circuit.
Restricted lint screen or exhaust vent A clogged lint filter, transition duct, or outdoor vent reduces airflow enough to trip safety thermostats or fuses even if the heater itself is still good.
Failed igniter (gas dryers) The igniter glows to open the gas valve coils, and when it weakens or breaks it cannot draw enough current to release gas to the burner.
Bad gas valve solenoid coils (gas dryers) If the igniter glows white-hot but the burner never lights, one or both solenoid coils on the gas valve have failed and must be replaced as a set.

How to Diagnose and Fix

Identify whether your Kenmore dryer is electric or gas by looking at the supply cord (three- or four-prong plug for electric, or a gas line and 120V cord for gas).
Pull out and clean the lint screen, then vacuum the lint trap housing and check the exhaust vent from the back of the dryer to the outdoor cap for blockages.
For electric dryers, unplug the machine and use a multimeter to test voltage at the terminal block: you should read 120V from each hot leg to neutral and 240V across the two hot legs when the breaker is on.
Disconnect power, remove the front or rear access panel, and locate the thermal fuse (usually a small white or silver oval on the blower housing or heater can).
Test the thermal fuse for continuity with your meter set to ohms; a good fuse reads near zero ohms, and an open reading means the fuse is blown and must be replaced.
On electric models, test the heating element by disconnecting one wire and measuring resistance across the element terminals (expect roughly 10 to 12 ohms), then check for continuity between each terminal and the metal housing (any continuity means the element is grounded and failed).
On gas dryers, start a heat cycle and watch the igniter; if it glows brightly for 60 to 90 seconds but no flame appears, the gas valve solenoid coils are the likely cause and should be replaced together.
After replacing any failed part, reassemble the dryer and run a timed-dry cycle to confirm heat, then verify that airflow from the exhaust vent is strong and that the dryer does not overheat.

Parts You Might Need

Part	Notes
Thermal fuse	Amazon \| One-time safety device; test for continuity at room temperature (should read near 0 ohms).
Heating element (electric dryers)	Amazon \| Should measure about 10 to 12 ohms across terminals and show no continuity to ground.
High-limit thermostat or cycling thermostat	Amazon \| Snap-disc switches mounted on heater housing; test for continuity when cool.
Gas valve solenoid coils (gas dryers)	Amazon \| Replace both coils as a set if igniter glows but burner does not light.

When to Call a Pro

Call a qualified appliance technician if you are uncomfortable working with 240V electrical connections or if voltage testing reveals a supply wiring problem at the outlet or breaker panel. On gas dryers, any work beyond replacing the igniter or valve coils involves live gas lines and should be handled by a professional with LP or natural-gas experience. If you have replaced the thermal fuse and cleaned all vents but the fuse blows again immediately, an underlying short or control board fault requires a technician with a schematic and proper test equipment.
