Kenmore Dryer Not Heating — Causes & Fixes
1. Tripped or Partially Failed Circuit Breaker
Electric dryers run on a 240-volt double-pole breaker; if one leg trips, the drum may still spin but the heater loses power entirely. This is the quickest and cheapest thing to check before touching any internal parts.
- Go to your home’s electrical panel and locate the double-pole breaker labeled for the dryer.
- Even if it doesn’t look tripped, switch it fully OFF, wait 30 seconds, then switch it firmly ON.
- Run a timed dry cycle and feel for heat at the door opening within two minutes.
- If the breaker trips again immediately, stop and call an electrician—there may be a wiring fault.
2. Blown Thermal Fuse (Most Common Cause)
The thermal fuse is a one-shot safety device that permanently opens when the dryer overheats; once blown, it cuts power to the heater and must be replaced. Restricted airflow from a clogged vent is almost always the root cause, so clean the vent at the same time.
- Unplug the dryer from the wall outlet.
- Remove the back panel (typically 6–8 quarter-inch hex-head screws).
- Locate the thermal fuse—a small, oblong component mounted on the exhaust duct or burner housing.
- Set a multimeter to the continuity or resistance (Ω) setting and probe both terminals of the fuse.
- No continuity (open circuit) = blown fuse. Replace it with an identical-rated part.
- Before reassembling, disconnect the vent hose and clear any lint buildup from the hose, wall duct, and exterior cap.
- Reassemble, plug in, and run a test cycle.

3. Failed Heating Element (Electric Models)
The heating element is a coiled resistance wire that generates heat; a single break in the coil stops all heating while the drum continues to spin normally. Visual inspection or a multimeter test will confirm a break.
- Unplug the dryer and remove the back or front panel depending on your model.
- Locate the heating element housing—a metal box near the bottom-rear of the cabinet.
- Disconnect the two wires and test across the element terminals with a multimeter set to continuity.
- No continuity, or a visible break/burn in the coil, means the element is bad.
- Remove the two or three mounting screws, slide out the element, and install the new one.
- Reconnect the wires, reassemble the panel, and run a full cycle to confirm heat is restored.

4. Faulty High-Limit Thermostat
The high-limit thermostat sits near the heating element and shuts off heat if temperatures exceed a safe threshold; unlike the thermal fuse it can cycle, but it fails open and mimics a blown fuse when it goes bad. Always test it any time you replace a thermal fuse, because both often fail together.
- Unplug the dryer and access the heating element housing as described above.
- Locate the high-limit thermostat—a round disc-shaped component mounted to the element housing or exhaust duct.
- Disconnect its two wires and test for continuity with a multimeter.
- A good thermostat shows continuity at room temperature. No continuity = replace it.
- Install the new thermostat, reconnect wires, and reassemble.

5. Defective Gas Valve Coils (Gas Models) — kenmore dryer not heating
Gas Kenmore dryers use two or three electromagnetic coils to open the gas valve; when one coil fails the valve stays closed, the igniter may glow briefly but the burner won’t light. This is a common repair on gas dryers that are a few years old.
- Unplug the dryer and shut off the gas supply valve behind the unit.
- Open the front cabinet panel—remove the lint screen housing screws, then the lower toe panel, then tip the front panel forward.
- Locate the gas valve and the coil pack mounted on top of it.
- Inspect the igniter: plug the dryer in briefly and watch through the burner opening. If the igniter glows orange-white but no flame appears, the coils are the likely culprit. Unplug before continuing.
- Unplug the wire harness connectors from the coils and pull the coil pack off the valve.
- Snap the new coil pack onto the valve, reconnect the harness, and reassemble.
- Restore the gas supply, plug in, and run a cycle to confirm ignition.

6. Worn or Broken Cycling Thermostat
The cycling thermostat regulates operating temperature by cycling the heater on and off throughout a drying cycle; when it fails open the heater never turns on, producing a no-heat symptom identical to other causes. It is inexpensive and worth testing if the parts above check out fine.
- Unplug the dryer and remove the back panel.
- Find the cycling thermostat—usually a small disc mounted on the blower housing or exhaust duct, separate from the high-limit thermostat.
- Disconnect its wires and test for continuity at room temperature.
- No continuity = replace the thermostat.
- Install the new part, reassemble, and run a test cycle.

Frequently asked questions
How do I know if my Kenmore dryer’s thermal fuse is blown without a multimeter?
Without a multimeter, it’s difficult to confirm definitively, but a strong clue is that the drum spins normally while producing zero heat. You can temporarily bypass the thermal fuse (connect the two wires together) for a single short test cycle—if heat returns, the fuse was blown. Do not leave a fuse bypassed permanently; replace it immediately, as the fuse is a critical safety device.
Why does my Kenmore dryer keep blowing the thermal fuse?
A thermal fuse that blows repeatedly is almost always a symptom of restricted airflow, not a defective fuse itself. Check the full exhaust path: the flexible vent hose behind the dryer (replace accordion-style plastic hose with rigid or semi-rigid metal), the wall duct run, and the exterior vent cap. Also verify the interior lint screen is cleaned after every load. Overloading the dryer can also contribute to overheating.
My Kenmore gas dryer igniter glows but won’t ignite — what’s wrong?
If the igniter glows bright orange but the burner doesn’t light, the gas valve coils (radiant sensor coils) have almost certainly failed. The igniter reaching full temperature is supposed to signal the coils to open the valve; if the coils are open-circuited, no gas flows. Replace the coil kit as described in Cause 5 above. Confirm the gas supply shutoff valve is fully open as well.
