Dryer no Heat. New Thermostat Burnt Out.

I've been having a problem with my dryer not producing heat. I tracked it down to a faulty thermostat. After replacing the thermostat the heat worked fine, for about 10 minutes and then stopped again.

I checked the newly replaced thermostat and it had burnt out again! Is the fuse not doing it's job? What can I do to track down what's causing this thermostat to short out like this?

    pkaiser74 - Thanks for the suggestion. I have replaced both the hi limit thermostat and the cycling thermostat. Immediately after this was done the dryer was producing heat like normal, but once my wife tried to do a load of laundry the dryer started blowing only cold air again.



    I bypassed the cycling thermostat by connecting the red and purple wires to each other wrapped in electrical tape and the heat is back. So, it looks like the cycling thermostat has gone bad AGAIN. What could be causing this thermostat to go bad again? I don't want to buy another cycling thermostat and put it in just for it to go bad again. Any ideas?

Troubleshooting heating element on samsung steam dryer


DRYER OVERHEATING:

Heating Element
A defective heating element can make a dryer too hot or not heat at all. . If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.

Other Causes and Conditions
Air Flow Problem
Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.

Cycling Thermostat
Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.

Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.

Blower Wheel
A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer.

I have a Samsung dv220aew xaa dryer that does not produce heat. I've replaced the heating element, the thermistor, and the thermostats with the problem remaining, what could be the problem?


ARE U GETTING THE RIGHT AMOUNT OF VOLTAGE AT THE CONNECTION,? i VE SEEN IN SOME CASES WHERE THE MACHINE ONLY GETTING 120 AND WILL RUN BUT NOT CREATE MUCH HEAT? THE DRYER USES 120 TO RUN THE CYCLE BUT NEEDS A FULL 220 FOR THE HEAT CYCLE TO WORK, THUS IF UR MISSING VOLTAGE IT WILL NOT HEAT? ANOTHER CULPRIT COULD BE A BAD TIMER STUCK ON COOL DOWN OR FLUFF CYCLE AND WILL PRODUCE NO HEAT?

I have a Whirlpool electric dryer MOD WED5540S!) SER MU2124790 TYPE DWJR-ELE-2406026-FM54 the dryer runs good, but will not heat. I have checked the air flow and its clear. I've checked all...


Limit thermostat , heres how you check thermostats Set your multimeter to the R X 1 setting. Take each of your meter's probes and touch one to each terminal. You are testing for continuity, and you should receive a reading of either zero or infinity. At room temperature, testing the thermostat should produce a reading of zero. But if a thermostat is tested when it is heated to its limit, a reading of infinity should be produced. I strongly recommend that you test your thermostat at room temperature.

Welcome jessegonzales
Check the outside vent leaving your house does not have a screen on it.
Take the screen off. Even half blocked and the dryer will not dry well.



Possible solutions

1. Defective Heating Element

The heat produced from heating elements is measured in watts and a normal heating element will produce about 4500 watts of heat. If the heat element is shorted to the case, this will cause the heating element to operate on 110v and use only about 1/2 of the element wire. In effect, the heat produced will be only about 1/4 of the amount that should be produced and the end result is an increased drying time.
The normal method for checking a heating element is to check it continuity. With the element unplugged you can check the continuity from one wire post to the next. If the circuit is open, thent he heating element is faulty.
However keep in mind that the element could be shorted to the case as described above. In this situation it is possible to have continuity, but the element still be the source of the problem.
Let me know.

3.Defective Thermostat
The thermostats are responsible for maintaining the proper temperature in the dryer. Check the exhaust temperature of the dyer and if the temperature is above 150 degrees, you will most likely need to change the operating thermostat.

The thermostat can also fail in the opposite mode. It can prevent the element from heating at all. A failed continuity check at room temperature will verify this condition.

There are some special thermostats that are single pole double throw. These thermostats are often used to control the timer when set to the Automatic Dry cycle. If the dryer timer will advance in the Timed Dry cycle but not the Automatic Dry cycle, then the thermostat could be the problem.

4. Defective Gas Valve Coil (Gas Dryer Only)

If the gas dryer will light once but will not relight until it cools down, it is likely the gas valve coils are faulty. These coils loose some strength when subjected to heat. When they become old, the addition of heat may be enough to prevent them from opening the gas valve when hot. However the coils still work when when cool.

An easy way to diagnose the coils when the burner is not lighting, watch the ignitor. If the the ignitor glows for 10 to 15 seconds but no flame is created, then the coils are faulty. If the ignitor is not glowing the problem is elsewhere.

Recent Customer Symptoms:
The dryer burner doesn't always come on when starting. If the burner does come on, once it goes off if won't come on again until the dryer cools down.

One of these will solve the problem!
Thank You
