Dryer not heating...everything seems OK

So I've done research on how dryers work, how to test, etc.  The dryer will tumble, but will not heat.
I went straight to the heating element. It passes continuity test, so I looked at it live. The element actually has 240V across it, but still is not heating.  If it has continuity and voltage across it, why won't it heat?

    The testing I have done should bypass all of this, but yes, all these items are in check.  I even have voltage across the element, only it still does not heat. Before checking that, I shorted the thermal fuse and eliminated that possibility.  The only solution I can think of is that the element is shorted, so it passes continuity, but it's not heating because the current isn't passing thru the entire coil?

Y'ou are zeroing in on your problem. Read the info below and hopefully you will have your answer:
If your dryer doesn't heat, check these:

Power from the house
Heating element
Thermal fuse
Wiring
Power from the house Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.

Heating element Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.

Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)

Wiring A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

    You are correct. Often an element will pass the continuity test and still be shot. I would replace the element. good luck.

A tumble dryer that isn't heating up at all needs checking with a continuity test meter. The most common cause is a heating element failure, or t.o.c's going open circuit. It depends on which make and model of tumble dryer you have as to how easy it is to get to the relevant parts. Some tumble dryers have heating elements that are easily accessible by removing the back panel, and can be tested for continuity or checked for obvious breakage. Others though have their heating elements inside, which aren't accessible without stripping the dryer down. Tumble dryer heating elements are always protected by thermal fuses which are usually simple devices with 2 wires connected. They can be tested for continuity with a test meter
or
If power is getting to the tumble dryer and the socket is definitely OK, then the most common problem with tumble dryers not working is when the door micro switch fails, or the catch on the door that operates the switch either breaks or no longer activates the door switch. Check for broken door catches. There is usually a plastic peg on the door that pushes through a hole in the tumble dryer's casing where the door catch is. Closing the door should operate a simple micro switch. If the plastic peg is broken or bent it might not operate the switch properly

In your case it is better that y ou call in an engineer to test it. Also overloading and blocked filters can cause the thermostat to cut out and they can also go with simple wear and tear. Check your service manual for spare parts etc

There is no heat


Disconnect power and access your dryer fuses. Check and test your fuses for "continuity". Most likely, a white thermal fuse. Can possibly be your ignitor or heat element as well. Is your dryer gas or electric?

No heat to tumble dryer


Check the thermal disc with an OHM meter. One will be next to the heat element (high limit) and another on the air exhaust area which is the low limit.

Dryer tumbles won't heat


The problem could be related to one of the following; Not enough power from the house, a bad or broken heating element, a bad thermal fuse, or a brake in the wiring.

Solution
Check the house voltage for 220-240
Do a continuity test on the heating element.
Do OHM reading on thermal fuse.
Check wiring to heating element.

theordis:

When you say electrical power is working Ok ,I would assume you are saying this because the dryer is tumbling.
Which could mean you are only getting 120 volts to the unit but it will not heat with out 240 volts.

If you are getting 240 volts.
You could have an open thermostat, an open heating element. A bad timer contact or a open switch on the motor.

All these can be tested with a Volt-Ohm meter.

((((The Electrical supply must be turned off and at least one wire dissonnected from the component being tested.
