Start with the dryer setting and the two house breakers when a Kenmore dryer is not heating. If both check out, read the first three digits of the model number. A 110 Kenmore is built by Whirlpool and a 417 by Frigidaire, and that decides which heat parts fit.
Kenmore never built its own dryers. Sears sold them, and other companies made them, so the fix for a Kenmore dryer not heating depends on whose dryer you actually own.
Most of my service calls were Whirlpool-family machines, and Frigidaire showed up on the list too, so when a Kenmore came up, the model number was the first thing I wanted. I checked the breakers and read the label before the back panel came off. You should too.
Kenmore dryer not heating: start with the free checks
First, prove there’s no heat. Whirlpool’s test is to pick a heated timed cycle, run the empty dryer for 5 minutes, then open the door and feel inside.
Cold inside? Work down this list before you buy anything for your dryer.
- The setting. Air Only or Air Fluff tumbles with no heat at all. Whirlpool and Frigidaire both warn about it. Pick a heated cycle and a heat setting.
- Both breakers. An electric dryer runs on a 30-amp circuit with two breakers, Whirlpool says. One runs the motor that turns the drum, and the other runs the heating element. If only the heat side trips, your drum spins and the air stays cold.
- The power cord. An electric dryer needs 240 volts. Unplug the dryer and make sure the terminal screws where the cord attaches are tight.
- The voltage. If the breakers are fine and you suspect the supply, Frigidaire’s advice is to have a qualified electrician check for 240 volts at the outlet.
Reset any breaker you find tripped. If you’ve got fuses, Frigidaire says to replace a blown one.
Find out who built your Kenmore dryer
Your Kenmore model number starts with three digits and a dot. Sears PartsDirect says those three digits identify who manufactured the appliance.
On a Whirlpool-built Kenmore, Sears PartsDirect puts the model label at the top of the door opening. Open the door and look along the upper inside frame.
- 110. Sears PartsDirect’s page for a Kenmore 110 dryer says the 110 prefix indicates a Whirlpool-built Kenmore dryer. Its parts lists carry Whirlpool’s WP part numbers.
- 417. Sears PartsDirect’s parts list for a Kenmore 417 dryer includes a Frigidaire blower wheel assembly, so that one’s a Frigidaire underneath.
- Anything else. Type the full model number into Sears PartsDirect and look at the brand names and part numbers in the parts list.
It’s the same method we use for a Kenmore oven that won’t heat, where the 790 prefix points to Frigidaire. Once you know the maker, follow that maker’s support pages: Whirlpool’s dryer not heating checks for a 110, and Frigidaire’s “My dryer is running, but does not seem to be heating” article for a 417.
Gas Kenmore dryers
Whirlpool’s checks for a gas dryer start with the house breaker or fuse too, so look there first.
Then look at the gas shutoff valve on the supply line behind the dryer. Whirlpool says the drum will turn but the dryer won’t heat if that valve is closed, and the valve is open when its handle is parallel to the gas pipe.
Frigidaire adds two more. If you run on LP, an empty tank means no heat, so refill or replace it. If the natural gas supply was interrupted, call your gas company.
That’s where I’d stop. Past the shutoff valve, the burner parts are gas work, and I’m not licensed for gas. Call a pro for anything beyond the valve handle.
The heat parts on each Kenmore
On an electric Kenmore that passes the free checks, the next suspects are in the heat circuit itself. One r/DIY commenter described that circuit well:
“Look up how to open your dryer and inside is going to be what amounts to a simple circuit with some thermostats, a heating coil, and some thermal fuses, all in series. Something in that loop failed. So with the dryer unplugged, one by one, check connectivity across each pair of connections with a multimeter.”

That’s the right order. Unplug it first, every time. I carry a multimeter on every call, and it’s the tool that saves you from buying parts you don’t need.
110 models (Whirlpool-built)
For a Whirlpool-built Kenmore, Sears PartsDirect lists these heat parts by name and number:
- Thermal cut-off fuse kit, 279816: listed for no heat, or a dryer that stops heating after a short time.
- High-limit thermostat, WP3977767: the safety limit that shuts off heat when the dryer runs too hot.
- Operating thermostat, WP3387134: regulates normal drum temperature.
- The heating element: Sears calls it a top suspect when the drum tumbles and the air is cold.
Those numbers are for one 110 model. Confirm yours against your own full model number before you order, so you don’t end up with a part your dryer can’t use.
417 models (Frigidaire-built)
The Frigidaire-built 417 parts list names different safety parts: a thermal limiter, part 134120900, and a high-limit thermostat, part 3204267. Same idea, different pieces. Don’t order a Whirlpool kit for a 417.
Owners do find the fault this way. The r/DIY poster with a spinning, cold Kenmore came back with an update: “it looks like it’s the thermal fuse.”
It heats but clothes stay damp
If your 5-minute test finds heat but loads still take forever, look at airflow, not heat. Whirlpool says the likely cause is the vent or restricted airflow, and that the vent line to the outside must be cleaned every one to two years, or sooner if drying slows down.
Fix the airflow before you replace a blown thermal fuse. Sears PartsDirect’s advice is to address venting first so a new thermal fuse doesn’t fail again. Sears notes that airflow restrictions commonly trigger safety parts like thermal cut-offs.
For the full list of slow-drying causes, see why a dryer takes longer than normal. The general dryer not heating but drum spins guide covers the same heat circuit on other brands.
Kenmore dryer not heating questions
How do I tell if my Kenmore’s thermal fuse is blown?
Unplug the dryer, take the wires off the fuse and check it with a multimeter set to continuity. A blown fuse shows no continuity. On a 110, Sears PartsDirect sells it as the thermal cut-off fuse kit 279816; a 417 uses a thermal limiter instead.
Why would only one breaker stop the heat?
Because an electric dryer uses two. Whirlpool and Frigidaire both say one side runs the motor and the other runs the heat, so a trip on the heat side leaves the drum spinning with cold air.
Is an old Kenmore dryer worth fixing?
A breaker reset costs nothing. For a bigger part on an older unit, our appliance age calculator compares typical lifespans and runs the 50% repair test.
