Kenmore elite elec dryer, 110.64972300. runs no heat
Kenmore elite elec dryer, 110.64972300. 10 ohms at heating element, 0 ohms at thermal fuse, thermostat + thermal cutoff. 17000 ohms on thermister at about 62 degrees. got my full 220ac. All vents are clean and free.
if i connect each leg of the heating element to frame i get 110 on each but if I put it on both legs when its running I only get 75 vac.

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 .

#1 reason of dryers going bad is woman's bra's....the medal sewed in the cloth itself for support comes out and goes into the small holes and hits the heating element on both sides and shorts it out...Change the heating element....It's in back of dryer.
in addation to checking the high limit t-stat have you checked the thermal cut off (the small t-stat) on the heater housing where the element fits into, the high limit t-stat and the thermal cut off BOTH shoud have 0 ohms (the thermal fuse is in the blower housing) the cut off is on the heater box, if you have checked those to be good, check that the heat relay on the control board is closing and sending power to the element, if not replace the control, if all above are good then the motor switch is bad and not sending power to the element(thats a built in safety feature so the dry would never heat when the motor isnt running)the element of course heats only when 240 volts ac is to the element ,120vac from the relay on control through the high limit t-stat then through the thermal cut off finally to the element and 120vac from the motor switch for a comined 240 vac
With a multimeter. It should ohm out at 0 on Rx1. But if your dryer is still running than it is not your thermal fuse it is one of your thermal cutoffs which should be attatched to the side of your element., or your element is bad.
for using FixYa. No Heat
issue in an electric dryer is usually caused due to three things mainly:
Thermal Fuse, Wiring Harness and/or Heating Element. Start with checking the
Thermal Fuse which is mounted inside the back cover panel to the exhaust duct
and is mounted in white plastic housing. If that’s fine then the Heating
Element should be checked. Please do rate the solution if the
issue is resolved or post a comment for further assistance. Thanks Rylee
There is a thermal sensor attached to the housing of the heating element, you can check the thermal sensor by jumpering the two wires to the thermal sensor together, and then run the dryer and see if the heating element is now working, if the dryer is now heating up then replace the thermal sensor.
limit switch stuck open should be behind motor housing is a tight fit to get to but there are two there on the element one on vent tube the other is thermal switch recommend chang the two on the tube ck element limits should all read continuityif not reolace
You probably have a bad thermal cut-off . This is the small thermostat , located at the top of the element housing . This " thermostat " should read infinate resistance ( no resistance ) . You can put the 2 wires togather , and see if heat comes on . pt # 3399848 . Both thermostats , should read 0 resistance . They are normally closed . The thermal cut-off , will not reset itself , if open . This is a safety t-stat , for when dryer gets too hot , and will have to be replaced .
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.
If all of the components are reading ok then you need a timer. Touch your 2 leads together. 0 ohms rght. That means you have a complete circuit.If you get the 0 reading then the element must be otay. Bad timer. Take that fancy meater of yours and atttach one of them leads to the timer leg marked RH. Yank the wire off the terminal beore you test. Move the timer around. You should get the famous 0 reading along the way. If you don't then that means you have the bad timer.
