Tip & How-To about Dryers

Electric dryer will not heat?

If the electric dryer does not heat at all then there are some possibilities that have to be checked to confirm the fault.
1)check whether you are getting power to the dryer from electric out let to which the dryer is connected. The power problem can also occur if the fuse is blown or the circuit breaker is got tripped.
2) Other possibility for dryer not heating is the blown thermal fuse. The thermal fuse is located to the exhaust duct inside the back cover panel. This fuse blows out if the dryer gets overheated or any short circuit occurs in the house when dryer is in working.
3) The other possibility if the power is ok and if the thermal fuse is ok. Then the problem can be due to fault in the heating element. The heating element looks like a long coil of special wire. You can check heating elements continuity with an ohm meter. If there is no continuity that means the element is bad and you need to replace it. The heating elements cannot be repaired it should be replaced if faulty.
4) But if all the above mentioned possibilities checks out OK, and still the same problem, then there is a fault in the wiring. Check the main power cord of the dryer which you connect in the electric out let. If the power wire is got internally burned out or got cut in between the dryer will not get proper power and will not work Due to partial power.
This will help. Thanks.

No heat. I have checked the resistance on all three thermostats and got a reading of .1 on all of them. Any ideas on what to do next?

The OHMS reading confirms that all the coils/elements are in good condition and the fault is relative to a loss of voltage to the element. So when the dryer works there is no feed voltage to the element to heat and so this must be traced from the controller unit. It can be a fault in switching check for failure of relay or line break in wiring to the element.
Please take care when working with live power circuits and attempt ONLY if you can trace the supply voltage feed from the mains supply to the controller and to the element.

Electric dryer will not work at all?

Usually this is due to a thermal fuse being blown. To check for a blown thermal fuse: 1. MOST IMPORTANT, unplug dryer. 2. If this is an older model, pry up front of top cover of dryer using a flat head screw driver. Cover should be hinged on back side of dryer. 3. Lift up cover and look towards back of dryer near heating element (coils). 4. You should find a small metal part mounted near the heater and about the size of a bottle cap with two wires plugged into it. 5. Take a multimeter and set it to read continuity (the horseshoe symbol). It should read "ovrflo". 6. Test the meter by touching the meter probe tips together - the reading should change to zero or close to zero. If so, the meter is reading correctly. Many meters will also beep. 6. Take the multimeter test probes (2) and touch one probe to each plug on the back of the fuse at the same time - make sure to touch the bare metal plugs where the wires are attached. 7. If the meter reading changes to zero again, the fuse is good and this is not the problem. If not, the fuse is blown and probably is the problem. 8. If the fuse is blown, unplug the wires from the fuse and remove the fuse - may need a flat head screw driver and needle nose pliers to help remove the fuse. 9. Again, repeat steps 6 and 7 to verify if the fuse is blown. The meter should read about 0 if the fuse is good, if it still reads "ovrflo" then it needs to be replaced. 10. Get on the internet and do a search with the brand and model number / serial number of your dryer to get the thermal fuse part number. 11. Do another search for appliance parts stores in your area and start calling to see who has the part. Could also give band / model number to parts store to see if they have the part. 12. Go get and install the new fuse. Make sure to mount the fuse just as the original was mounted and remember to reconnect the wires to the fuse. 13. Push down the dryer top cover, should pop in place. 14. BEFORE YOU RESTART THE DRYER, CHECK THE EXHAUST DUCTS AND EXHAUST HOSE FROM YOUR DRYER ALL THE WAY TO WHERE IT EXHAUSTS OUTSIDE OF THE HOUSE. THERE IS LIKELY A BLOCKAGE OF LINT SOMEWHERE IN THE LINE. THIS IS WHY YOUR DRYER OVERHEATED AND YOUR THERMAL FUSE BLEW IN THE FIRST PLACE. IF YOU DON'T SEE A BLOCKAGE, AND YOU HAVE AN ELECTRIC LEAF BLOWER, HOOK IT UP WHERE THE DRYER CONNECTS TO THE EXHAUST HOSE AND THOROUGHLY BLOW OUT THE EXHAUST LINE TO OUTSIDE THE HOUSE. 14. Once you are satisfied the exhaust is clear, plug the dryer back in and start it up.

Control panel lights are on, but when you push the on button, nothing happens.


There can be many reasons why your dryer will not start or turn...

The most common causes are the belt breaking or jumping off, or the motor goingbad...

Here are a couple of tips that I wrote will help you to figure out why yourdryer will not run...

The appliance is operating without heat. Is there a standard heating element I can replace or could it be a number of possible faults. Thanks 4 your help

It is just one possibility of several as to why the dryer is not heating.
You nreally need a test meter to check the various components involved in the heating process.
Hope this is of some help to you.

Could it be the heating element/coils?

From the info you've given, I'd suggest confirming whether the electrical circuit breaker arrangement for the dryer is single-pole (one wire and handle, 120V) or two-pole (2 wires and handles, 240V).  The heating element requires 240V.  Also, you mentioned a "fuse box". Hopefully you meant circuit breaker panel.  The wiring in any house old enough to have fuses instead of breakers would be a major concern unless you're into indoor barbeques in the middle of the night.
