not likely the timer but it does control the heat circuit. suspect the fan-air flow is being blocked and the elements are cycling on a safety thermostat instead of the operating thermostat. check for blocked or restricted vent and plenty of air coming out the vent when running. check for a flapper on the vent not opening or only open part way.

KNOWING ABOUT THERMOSTAT.

A thermostat is a device for regulating the temperature of a system so that the system's temperature is maintained near a desired set point temperature. The name is derived from the Greek words thermos "hot" and statos "a standing".
What is a dryer thermostat?
A dryer thermostat is usually oval shaped and about an inch and a half in length. The thermostat contains a bimetal that opens and closes a pair of contacts depending on the temperature inside the dryer. The bimetal inside the thermostat is designed to bend at specific temperatures. When the bimetal bends, it pushes an actuator. The actuator then pushes on a contact, opening the electrical circuit and breaking the electrical connection to the related component. When the thermostat cools, the bimetal returns to its original shape and the contacts close, allowing the current to flow through the circuit.
Have you ever thought about how hot your dryer gets? Thermostats and thermal fuses are put in dryers for your safety and if you don't maintain them, you could be putting yourself, your house, and your family at risk.
Your dryer uses of a combination of heat and airflow to dry your clothes. The heat generated in your dryer is produced by a heating element controlled by a series of thermostats. If any of your dryer's thermostats are defective, the results can be disastrous.
Here's how it works: The dryer is turned on and heat begins to radiate from the heating element into the dryer's drum. The air in the drum passes by a thermostat. As the thermostat reaches its maximum temperature, the bimetal bends, cutting the power to the heating element. The circuit stays open until the bimetal cools. Because the heating element isn't providing additional heat, the dryer's temperature gradually falls. The bimetal returns to its original shape and the electric current flows to start the heating element again. This process happens many times throughout your dryer's cycle.
There are at least two thermostats in your dryer: cycling (operating) thermostat and hi-limit safety) thermostat. The difference between these two thermostats is their opening and closing temperatures.
The cycling thermostat is typically found in the path of the air leaving the drum. A cycling thermostat is usually found on the fan housing or just under the lint filter area, on the blower wheel housing or inside the venting/exhaust system.
Some dryers may have as many as five thermostats - one for each of the different heat cycles. The temperature setting or cycle selected determines which thermostat is used to control the heat. If your dryer is malfunctioning on the low heat setting, the thermostat for that particular setting is probably defective.
The thermostats for the high and medium temperature selections are not the problem. However, if the dryer isn't working properly for most of the heat settings, it's probably a problem with your vent rather than the thermostats.
The hi-limit thermostat protects your dryer from overheating. This thermostat is usually found on the heating element, housing, or cage assembly. If the airflow in the dryer becomes obstructed by a plugged or improperly installed vent, bad drum seals, or a defective blower, the high-limit thermostat cuts power to the heating element. This means there are other problems with your dryer.
In conjunction with thermostats, dryers use thermal fuses as a safety device. Some dryer models may have two thermal fuses to detect extreme heat. If the hi-limit thermostat fails to cut power to the heating element and the element gets too hot, the thermal fuse blows and cuts all power to the dryer. This could mean that a thermostat is defective or something is wrong with your venting duct, filters, seals, or blower. You cannot reset thermal fuses so once they blow they must be replaced. Get the proper replacement fuse for your model and replace the hi-limit thermostat as well. Never bypass a thermal fuse.
Have a look at your dryer's manual for the locations of its thermostats. It's unusual for a dryer's thermostat to continue operating at a different temperature than originally intended and the only way to test for this would be by checking the temperature of the exhaust. You can do this by placing a pocket thermometer inside the exhaust vent. This test is done with the dryer running, so be extremely careful.
Checking continuity is another way to test your thermostat. There's a wire leading to each of the thermostat's terminals. The wires are connected by metal slip-on connectors. Label the wires before you remove them so that you're able to correctly reconnect them later. To remove the wires use needle nose pliers to pull on the connectors - don't pull on the wires themselves.
Set your multimeter to the RX1 setting. With the thermostat at room temperature, touch one meter probe to one terminal and touch the other meter probe to the other terminal. You should receive a reading of zero. If a thermostat is tested when it's heated to its limit, a reading of infinity should be produced. You should replace your thermostat if it fails either of these tests.
The thermostat is attached to the dryer with two screws. Remove both screws and discard the faulty thermostat. Install a new thermostat, securing it in place with two screws. Reconnect the two wires, put your dryer back together, and restore power to the dryer. Run your dryer through a cycle to make sure it's working properly.
Safety Warning: Before performing any tests or repairs on your dryer disconnect the power source to eliminate the risk of electric shock. You can do this by unplugging the dryer, removing the related fuse from the fuse box, or flipping the appropriate switch on the breaker panel.
For better protection of your family and yourself - maintain your dryer regularly. But if you can't do it yourself, make sure you contact a qualify service technician to do it for you. www.victorwod1234.blogspot.com

Zanussi tumble dryer keeps cutting out


little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective or has a short if its grounding out? Which in turns causes blown fuses or thermostats or overheating.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

I need a new thermostat (or is it a safety cut-out) for the heater element on a Zanussi 910R


Thermostats are temperature  cut out devices. An advanced form of temperature control could be achieved using a RTD probe and a temperature controller. By this way operating temperatures fall in between maximum and minimum ranges that could be manually preset. Thermostats are the last line of safety for any heater coil / element.

Dryer powers up but won't start - smell of electrical burning. Is it the motor bushes? zanussi TC7103W


Electric dryers usually have a motor with a switch that prevents the heating element from being powered until the motor is spinning. In series with this are limit switches to prevent overheating if there is too much lint or too little air flow around the heating element. Also, the motors are induction or brushless. So the smell is coming from the heating element burning off some lint nearby as it reaches the high limit temperature and shuts off. This can be due to two conditions if we can assume the motor is running (has a switch that is closing to power the heating element). The most likely condition is that the drive belt is off the pulley or broken and the drum is not turning. You will be able to tell this easily by sounds or by opening the door to see the drum slowing down. If that's not it, examine the blower which forces air through the drum. There are a lot of variations, so look for air intake and drum exhaust ports that can be clogged with a sock, lint, etc.
