Question about Kenmore Dryers

1 Answer

Thermal element failures continue...

Kenmore elite dryer model 110.66962500 heating element has been replace now twice in 3 months. Thermal cut out is working but heating element failed each time. I've checked to make sure that all the vents are free of lint and not clogged, made sure that the circuit breaker is working properly and that I'm getting the proper voltage across the connection. But the element has blown again for the 4th time! Any suggestions?

When you install the replacement heater, be very careful not to stretch or bunch up the heater wire. The metal is relatively brittle and cracks easily. Also, if coil turns are too closely spaced, that causes a hot spot that is more likely to burn out.

Also, make sure the terminal connectors are clean and free of corrosion. A poor connection can cause overheating right at the terminal.

Check all ductwork inside and outside of the dryer for lint or other blockage. In particular, check the outside vent damper to make sure it opens and closes properly.

Finally, make sure the blower is securely attached to the shaft, and that the motor turns freely without bearing slop or grinding. A loose fan will slip on the shaft, resulting in inadequate air flow. This can burn out the heater and leave the clothes damp or cause a prolonged drying time.

SOURCE: Dryer runs but doesn't heat up when sttings call for heat.

You may need to do some troubleshooting. This can be done with the machine unplugged - you may have to activate the start switch, belt switch (if it has one) and the motor centrifugal switch manually.
Tip for troubleshooting 220v systems - clip one lead of a ohm meter to either L1 or L2 on the terminal block. It doesn't matter which one. According to the tech sheet (under console) follow the path for current from your clipped terminal, through the heating element, to the opposite terminal. All the readings should be less than 100 ohms, until you reach the failed part. Confirm failure by disconnecting a lead from the suspected part, and test only that part.

Live troubleshooting is sometimes slightly easier, but much more dangerous than the procedure described above. - It is definitely not recommended for beginners, or for professionals, if it can be avoided.

SOURCE: kenmore elite elec dryer, 110.64972300. runs no heat

Pull one wire off the element and start the dryer in a heat cycle . Check power from that wire to the cabinet . Touch the meter to the terminal you pulled that wire off of , and check that voltage . You cannot get correct voltage by checking across the element . Trace the wire NOT getting 120 volts . It will either go to the timer or motor . It will lead you to the problem .

Kenmore dryer blows cold air. I replaced heat element still no luck? model 96263800


It doesn't necessarily mean the heating element is busted when an electric dryer stops heating. The heating circuit is not just composed solely by the heating element, it is composed by the thermal cut-off, high-limit thermostat, cycling thermostat, motor centrifugal switch, and the timer. The first thing to look at when an electric dryer stops heating is the thermal cut-off. It cuts power to the heating element when it blows most likely due to the failure of the high-limit thermostat. The thermal cut-off must be replaced, together with the high-limit thermostat, if found open. Click on the link below for the detailed instructions in troubleshooting this problem.

The dryer has power and works, but there is no heat?


If the heating element shorts to ground the unit will overheat while running until the thermal fuse trips cutting off power to the motor. I recommend replacing the heating element, and the thermal fuse. Be sure to check for a blocked exhaust vent before starting the dryer to prevent another failure. If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a appliance repair technician.

Dryer quit heating no power to element what is wrong?


The problem is most likely the thermal cut-off and the high-limit thermostat. The thermal cut-off blows when the high-limit thermostat fails and since these parts are wired in series with the heating element, power to the heating element is therefore terminated. Check the continuity of the thermal cut-off and if it reads open, replace it along with the high-limit thermostat.

You can bypass the thermal cut-off and the high-limit thermostat for troubleshooting purposes. Join together the wires of each part and insulate it properly then reconnect power. The two components indeed need to be replaced if the dryer heats up. If not and still no power to the heating element, check the continuity of the heating circuit. Check the continuity/resistance of the heating element if there's power to its terminals but doesn't heat. Replace the heating element if it reads open.

Let us know if you need further advice. Just indicate the exact model number of the dryer for accurate troubleshooting tips.

My kenmore dryer is blowing only cold air. What is wroge? We already checked the heating element and timer...???? This dryer is only 4 years old.


The heating circuit is composed not only by the heating element and the timer but also with a high-limit thermostat, a thermal cut-off, and a cycling thermostat. The high-limit thermostat and the thermal cut-off are both mounted on the heater housing to monitor and regulate the heater temperature while the cycling thermostat is mounted on the blower housing to monitor and regulate the temperature of the exhaust air.

All of these components are wired in series and a failure in any of them results in the dryer not heating. The proper troubleshooting is by checking the continuity of each of these components with a volt-ohmmeter and replacing the ones found without continuity (open).

A continuity check can also be done by bypassing each of the three components, never the heating element, and then starting the dryer. The dryer should heat, otherwise the problem is somewhere in the timer, the heating element, or the centrifugal switch within the motor. When the dryer heats up, unplug it then un-bypass one of the bypassed components and start the dryer. If the dryer stops heating then you have found the failed component; replace it. If the dryer does not stop heating, do the same to the remaining components until you find the failed one. Just make sure the dryer is unplugged before touching the components.

Replace both the high-limit thermostat and the thermal cut-off if any of them has failed. Indicate the exact model number of the dryer if you need further or more specific advice.

Kenmore elite , no heat


Check the following to address this issue.




1. No power to the dryer
Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.

2. Heating element
A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.

3. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Kenmore Elite dryer won't heat but otherwise operates normally


Make sure you have 220V. The dryer will work (no heat) if only getting 110V. Check your thermostats with your Ohm meter. Mkae sure plug is disconnected and you disconnect thermostat wires. Should have continuity. Just because you have checked your heating element and you have continuity that does not mean it is good. How can this be? Easy, sometimes they (coil in heating element) break and arch against the housing or ceramic insualtors (depending on model) and you will have continuity. This just happened to mine and without a visual inpsection of the heating element do not aaume it is good.

Kenmore HE4t Dryer - no heat


The usual suspect for a Kenmore HE that runs, but doesn't heat is a thermal cut-out or the thermal fuse. Although they are a bit more resilient, in some cases the heating element itself could be bad. The way to check: 1. UNPLUG THE DRYER, FIRST. 2. Remove the bottom kick plate on the front of the dryer. 3. Remove the blower fan cover directly under the lint screen. There should be a couple of 1/4" screws holding it on. 4. Directly behind the blower fan cover on top of the blower fan housing are two components. One is the operating thermostat, and the white one is a thermal fuse. The fuse is a one-shot fuse that must be replaced if it is bad. 5. To the right is the heating element housing. There are two additional components mounted on the side of the element housing. The component furthest to the back is the thermal fuse. The one one closest to you is the hi-limit thermostat. 6. Check the continuity of thermal fuse and the thermal cut-out. They both should read a short. Additionally, check the resistance of the the heating element. The element should read something low (less than 20 ohms). 7. If the thermal fuse reads open, replace it. If the thermal cut-out is bad, replace the hi-limit thermostat with it. They are usually sold as a set. If the heating element is bad, you will need to disconnect all electrical leads and remove one 1/4" screw holding the element housing to the bottom casing. Pull the entire element housing from the dryer. Depending on model, sometimes the element slide out of the housing, sometimes you will need to remove a few screws to open it up. I hope this helps you.
