Question about Kenmore 63942 Dryer

Kenmore Dryer will not heat

Dryer stopped heating. Have used service instructions inside with multimeter...fuse looks ok, the hight limit thermostat shows good, and when I check the three resistances on the gas valve coil - terminals 1 to 2 read 1399 (1365 +/- 25 typ), terminals 1 to 3 573 (560 +/- 25) and terminals 4 to 5 read 1305 (supposed to be 1220 +/- 50. This made me think the coil was bad so I ordered a new one...but it reads the same. Does anyone know if the terminal 4/5 range is really 1270 max or if 1305 is ok. Next step - I think - is to order replacement machine control electronics ($170). Any other suggestions...help???

    Don't see any reset button. Checked the voltage coming out of the control board to the thermal fuse (ok) then the high limit thermostat (ok) and then it goes to the valve controls. There are five wires...the black wire which looks to connect to the motor centrifugal switch per the wiring diagram...is not reading voltage. The other connections are all live. Any way I can post the wiring diagram? Keep in mind the dryer runs - everything seems to work but the heat. (Julie)

Does the limit switch have a reset button on it or is it an auto reset? Have you tried depressing the reset button on it if it is a manual reset? Have you checked your voltages to the gas valve, ignitor to make sure they are being called to come on? Trace your electrical connections from your electronics to these items. If they are not being told to come on, then you know it is the electronics. Also, have you checked the continuity of the door switch, and the ignite? These are all suggestions that must be ruled out before replacing parts.

3-5 ACCESS TO THE BLOWER WHEEL OR THERMOSTATS

To get to the blower wheel, remove the back of the dryer.

The blower wheel is under the bottom of the lint screen duct to your left, as you look at the back of the dryer.

The operating thermostats are at the blower wheel outlet.

In electric models, the hi-temperature cutout thermostat is mounted to the heat riser.

3-6 TEMPERATURE CONTROLS AND HI-TEMP SAFETIES

These clothes dryer machines use operating thermostats to control the temperature inside the drum, and hi-limit thermostats to prevent overheating of the dryer drum.. Many machines also have extra temperature controls, such as bias thermostats and heaters, hi-temperature cutoffs, and thermal fuses.

Bias thermostats are just like regular operating thermostats, except that they are mounted inside a bias heater. When the bias heater is energized, it generates a small amount of heat, which causes the operating thermostat to open sooner, keeping the dryer drum cooler inside. Thus a bias heater allows a single operating thermostat to act like both a hi-temp and a lo-temp operating thermostat.

A thermal fuse is found on the blower outlet, right next to the operating thermostat(s.) This fuse will blow when too high a temperature is sensed at the outlet; usually when one of the operating thermostats has failed. If it blows, the motor may not start, or you may get no heat (no voltage to the burner.)

A thermal cut-off is mounted on the clothes dryer heater box. It is a back-up for the hi-limit thermostat. Whenever you replace it, you should replace the hi-limit thermostat, too. A high-temperature condition causes it to open, an overheated grounded heat element may also cause it to open.

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.

I have an older model kenmore 110.96529810 dryer. I just replaced the heating element and it still isnt heating up...whats next


You need to check the "Thermal fuse","thermal cut-off" and "high-limit thermostat". Check all three with a multimeter for continuity. Replace as needed.

The dryer is working, however it is not drying. THe air is room temperature. I beleive I need to replace the fuse. How do I know which to replace?


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.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse. To test the thermostats or fuse, set the multimeter to the ohms setting X1. Touch one probe to each terminal. You should get a reading of either zero or infinity. At room temperature, the thermostats should have a reading of zero. When the thermostats are heated to their limit temperature, they should switch off and you should get a reading of infinity. The fuse should be tested at room temperature for continuity.

My 700 series dryer 67741600 will not heat is it the heating element or could it be something elsse


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.

Additional Check points.

  • Test the centrifugal switch
  • Test the timer motor

I need to know where the time delayed fuses are on a kenmore 500 electric dryer??? anyone know?


the only fuse on a dryer might be on the electronic control panel there are no time-delay fuses inside the unit,do you have power to the unit? or does it stop heating or quit all together,if it quits heating its probably your hi-limit thermostat on the element case or cycling thermostat

My kenmore 70 series dryer is not heating up. At first it just took longer and longer to dry, but now it isn't drying at all. This happened after the dryer was moved in order for the washing machine to be...


Not funny at all, I suspect. It sounds like the problem originated due to a faulty high limit thermostat or a partially burnt heating element. I would replace the thermal fuse and the high limit thermostat. These two components can be purchased as a set. Also check the heating element. It can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity indicates a bad component. The thermal fuse is normally attached to or near the exhaust duct and the high limit thermostat is attached to the internal ductwork. The thermal fuse can be tested in the same manner. I will attach a photo of a high limit thermostat and thermal fuse for reference. Sorry for your trouble and I hope this helped. Best wishes.

Dryer does not heat ellement is good


If the dryer won't heat and the heating element is good, then check the thermal fuse and the high limit thermostat. The thermal fuse is located just inside the rear of the dryer and is mounted on the exhaust duct. Test it for continuity using a multimeter. A lack of continuity indicates a blown thermal fuse. '
The high limit thermostat is a small round, black device mounted on a metal plate and attached to the internal ductwork with two screws. It can be tested for continuity. It should have none. If it has continuity it is faulty. I am attaching a photo of the thermal fuse and high limit thermostat for reference. Hope this helped and best wishes.

Dryer won't heat, otherwise functions. we unplugged the dryer and reset the circuit breaker although it did not trip. is there anything else that we can do before we call to have it repaired?

Not heating


Hi


Things that could stop a electric dryer from heating:
  • house fuse or breaker ( needs two of them )
  • heating element, burnt wire
  • thermostat(s), thermal fuse ( not all models ),
  • motor heat switch, timer, selector switch,
  • burnt power cord/plug.
You can check these things using an ohmmeter/multimeter from here.


Things that could stop a gas dryer from heating:

  • glow bar igniter,
  • thermal fuse ( not all models ),
  • coils on the gas valve, gas valve, thermostats,
  • motor heat switch, timer, selector switch, sensor.

A page for checking gas dryers is here.
