My tumble dryer only blows cold but the drum rotates. I think this could have happened because the filter was not cleaned for 3-4 loads and; therefore, the dryer may have over-heated. I have looked for some kind of obvious reset switch but can't find one. I have also purchased a new heating element and fitted it but still get cold air only. My latest theory is that the last 5 mins of the cycle are for airing, i.e. cool air only, and that the timer switch maybe sticking in this mode somehow? Any ideas?

    Same problem here as of yesterday. The dryer seems to work fine--it tumbles and air blows but the air is cold. Not sure what happened.

    I just discovered my dryer isn't heating, but everything else seems to be working properly. It is a Whirlpool MOD# LEN2000PG0. Is there a reset that will fix this problem in the short term? The vent and lint trap are both clean, but my sons have been drying their wet boots in it recently (we got our first snow of the year) , Maybe the drying time is too long and caused the "tco" to go out? Or would it have been more likely that the lint trap wasn't cleaned out properly at some point?

It's call a bad thermal cut-out. You should have a thermal cut-out and a high limit thermostat located adjacent to the heating element (usually mounted right on the heating element housing). They both should read a short or fairly low resistance in the case of the thermostat. If the thermal cut-out is blown it is not a resettable device and must be replaced. The tco is usually sold along with the high limit thermostat. It is HIGHLY recommended that you replace BOTH at the same time. DO NOT attempt to bypass any of these devices either. They are there as safety devices to prevent overheating. You could end up with a fire if you do. Now...with all that said, the tco will blow for a reason. Not cleaning the lint trap will contribute to it, but the big item is the ducting. If the vent ducting is clogged you will experience longer dry times and eventually the tco will trip again. Take the time to THOROUGHLY clean and/or replace your vent ducting from the wall all the way to the vent opening outside. In addition, while you have the dryer open THOROUGHLY clean the inside as well. This includes the air baffle where the blower fan is located. Rule of thumb: if you have lint INSIDE the dryer, it's clogged somewhere. Good luck and I hope this helps you.

Tumble dryer isblowing cold air only?

Your dryer is called smart dryer and in this case should have to generate familiy code E60 (or any of exactly fault code E61,62,63,64,65,66,67) if blowing cold air, as you explain. Means something is wrong with heating phase (drying).
So, in this case could be: Heater unit faulty; Wiring faulty; NTC sensor faulty/out of position; Electronic board faulty;
Thermostat faulty; and finally fun motor - but considering that it blows cool air I guess that is correct.

Whirlpool Clothes Dryer AWZ 121

It sounds like it is the belt. When the dryer heats up the belt expands a little and when it gets wore out, the tensioner doesn't have enough spring to keep it tight. It might work a little when it's cold before the belt expands.
This belt should work for your dryer but verify the length.

Here is a helpful Youtube video on how to do the repair.

Here is a link to the Service Manual

The bottom of this link shows some typical ways a belt runs past a tension wheel and links for your dryer. If you replace yours I would recommend taking a couple pictures before removing the old one so you can refer to them when installing the new one.

Simpson Dryer only blows cold air

It's either the fuse, heating element, thermal cut-off or thermostat

My Bosch Exxcel tumble dryer will only blow cold air

My whirlpool AWZ2303 only seems to be blowing cold

If your not getting heat from the machine its probably due to a faulty heating element. You can get the part at an appliance parts shop by bringing them the model number or you can call in a pro repairman to have a look and replace it. Do it yourself is cheaper by far but can be difficult on newer machines like this one.

Whirlpool not blowing or tumbling

check to see if belt is still on drum. might have broke. thats the only thing that would cause the drum not to rotate but still should have air flow. the blower wheel is hooked up to the motor itself. your problem might be the motor itself has gone bad. if belt looks good then your motor is not turning.

Will not heat, it only blow cold air, how do I change the heating element inside the unit

If the drum turns, it could be as simple as a blown fuse or breaker. The dryer has doule breaker or fuses at fuse panel. If the one blows, the heater will not work but motor willturn as motor rums on 110volts. It may be cut out thermostat or could be element, but check the power to the plug of dryer out let and make sure you getting 110 volts on from neutral to both sides and 220 between two live lines.

Whirlpool Ultimate care ii Dryer wont tumble

If your dryer doesn't tumble, check these:
Door switch.

Your dryer can't operate at all if the door switch is defective. It's inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. If it's defective, you need to replace it.
Dryers have a drive belt that turns the clothes drum. If the belt breaks, the drum stops rotating. Then you need to replace the belt, and often the idler pulley, because the pulley tends to wear out at the same time.
If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor:

Remove the belt,
Check for obstructions in the blower fan housing,
Manually rotate the shaft of the motor.

If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor.

If the motor rotates freely, run the motor momentarily with the belt removed and the blower in place. If the motor runs fine with the belt removed, there may be a problem with the idler pulley or the clothes drum. Try to rotate the drum by hand. If it is very difficult to move, correct any problem with the rollers or pulley, and then reassemble the dryer and try it again.

Go here to see a diagram for your model:
one of two types. "H" or "J"
