My dryer has no heat and the timer isn't advancing. The motor runs, lights on, timer and all sensors have been replaced along with coil reading infinite on ohm meter and fuse replaced. 240v at plug and at dryer. The no heat and timer not advancing problem started when a house breaker popped while I was running a welder on the same breaker.
Answer Hello J.H.,
I would first test the voltage to the unit with the unit on to see if there is a voltage drop when under load. If so, there could be an issue with the breaker or the associated wiring. This test should be done at the terminal block where the power cord connects to the unit. If the power supply checks out good and the prongs on the power cord prongs have no burned spots on them, the issue can only be the timer motor, the timer contacts, the heating element 279838, or the motors' 279827 centrifugal switch. Since the timer has been replaced, this eliminates the timer contacts and the timer motor.
Dryer comes on but switch will not move during cycle and dryer is not hot only cold air no matter which cycle it is on. Due to the timer switch not moving dryer run continuously with no heat.
Answer Hello Katherine. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. Also check the heater and thermostats and see if they are good. You can test these with a multi-meter TJMA-DM1. They should read closed for continuity. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
Dryer will come on for a few seconds, then will shut off. You notice a definate burning smell, but is hard to pinpoint. Thought it might be start switch, so I replaced that, but problem is still there. Although the burning smell seemed to be coming from the vicinity of the three switches, (start, cycle, and adjustable buzzer), I'm not so sure. The dryer shuts off whether it is on air fluff, or any of the three heat settings. Timer seems okay. Ran dryer with cycle switch disconnected. Same problem. Ran dryer with buzzer disconnected. Same problem. Seems a few of the wires coming off of (or going to) the start switch are hotter than others.
With the unit only running for a moment and then shuts off then the issue would be a bad centrifugal switch on the motor and the motor would need to be replaced.
Dryer will not come on. It was working and went off tried to turn it back on and when you push the start button it just makes a buzz.
Answer Hello Cindy,
You will want to start by checking the blower assembly to make sure that nothing got into the blower causing it to not allow motor to turn. Also check the belt to make sure that the belt has not come loose or broken.
My Kenmore electric dryer starts and heats up but on the timer once it reaches about a quarter of an inch before it should stop keeps running. Timer works well up to that point. The dryer will shut off if i open the door or manually turn the timer knob. i have replaced the timer already and still have the same problem.
Answer Fernando, Check the push to start switch circuit 3395385 it should have a "momentary"circuit, when the button is depressed. also check the buzzer 694419 it should have a rsistance reading of 1000 to 3000 ohms. In the timed dry selection, L2 power to the timer motor is supplied by the Wht/Blk wire from the motor switch. On auto dry selection, L2 power is supplied on the Orange wire from the heater element(only if or when the thermostat has reached temp.)and the timer motor advances. When the timer advances to the "cool down" cycle(the last five(5) minutes) the only closed circuit on the timer should be Black to Blue, all the other contacts should be "open" or shouldn't matter. At the end of the cycle the only "closed circuits at the timer should be TM to Orange, to advance the timer and Tan to blue , to operate the buzzer, all other circuits should be "open". If all the checks are proper, you'll need to check the red, white /black and orange wires from the motor to the heater and timer.
