How to test a tumble dryer that is not heating and change a thermostat that is faulty
This video is on a compact Zanussi but the testing and repair is very similar on most makes.
Your tumble dryer is not heating? Could Be One Of The Following:
If you have a Tumble Dryer that is not heating up but the drum is turning ok, then the chances are the thermal overload cut-out has tripped or the heater might have blown. Some older dryers have a red reset button on the back of the casing, just press the reset until you feel it click and you should have heat again white knight, creda and some other makes have this. Neff, Bosch dryers have a reset button but you will have to remove the heater cover panel to access it, you will find it just above the heating element (a black stat with small red button) simply press the red button and if it clicks you've fixed it or you can test it as in the video.
Why do Tumble Dryer Thermostats Fail?
In most cases it´s a fault generated by use or failure to use and maintain the tumble dryer correctly. A little care could prevent the hassle and cost on these repairs:
1 - The Tumble Dryer Filters must be cleaned!
If the air doesn't flow, the machine can overheat and the safety will trip. Any obstruction to the rate of airflow will affect the operation of the dryer and almost certainly cause a failure of the thermostat or, the safety thermostat to trip. If you don't clean the fluff or lint filters, don't fit them back properly or use the tumble dryer with damaged or broken filters it will affect the efficiency of your tumble dryer and as the temperature is no not kept down by cooler air being drawn into the tumble dryer. This increase in temperature can and does, rise high enough to trip out safety thermostats. Any obstruction to the rate of airflow will affect the operation of the dryer and almost certainly cause a failure of the thermostat or, the safety thermostat to trip.
2 - Tumble Dryer Vent Hose!
A blocked vent hose, with fluff or bended in the back of the machine stops the air flow from the machine, tripping the thermostats.
3 - Overloading your Tumble Dryer!
Putting too much clothes in your tumble dyer will affect the airflow, and almost certainly cause a failure of the thermostat or, the safety thermostat to trip.
4 – Always keep Tumble Dryer Condenser Unit Clean!
The aluminum plates at the bottom of condenser tumble dryers, to prevent any blockages caused by the fluff build-up.
5 - Opening The Door During The Drying Cycle!
The dryer has been switched off before the end of the drying cycle and not allowed the dryer to cool down correctly. ALWAYS LET THE DRYER GO THROUGH THE COOLING CYCLE.
i have a creda condenser tumble dryer t622cw model only the low heat on it was working so ive fitted a new heater element and now it keeps tripping the thermostat and it is cold air what can i do please

Hi I have a beko dc6130 w condenser tumble dryer it’s only 6 months old and all of a sudden no heat everything else is fine. We took the back of found reset button and when we pressed it , it wouldn’t budge like it wasn’t a button at all ? Any help would be appreciated . Thank you
Running costs are one of the most important things. During our tests we use an electricity meter to measure how much power the tumble dryer consumed. This lets us work out our own cost-per-cycle, letting us compare the difference in each drying mode.
My candy grand condensor dryer has stopped heating up does it have a cut off switch and where can the heating elements be found cleaned all filters emptied water tank

My candy grand condensor dryer has stopped heating upbitcstill spins does it have a e set button
Why is it taking so long (26 days???) to moderate a perfectly normal question?
I really need to know if this dryer is fixable or not or if I have to spend $1000 on a new one (yes the cheapest condenser model I can find in New Zealand is a fiver short of a grand or 500 quid UK).
I have a hoover VT580 which started blowing cold air. I replaced the heater element unit, and that didn’t work. I’ve just replace the ntc probe, and it is still blowing cold with both remold & the new heating element. Am I missing somethingk
That was supposed to read “still blowing cold with both the old and the new heating element. Am I missing something?”
How can I tell if the thermostat is not working or if it is the heater element
Hi Paul, I have a bosch WTA4408 tumble dryer.
It was failing to turn sometimes and the safety thermostat tripping due to this. Bought a capacitor off you guys and all good, setting away fine now even with heavier loads. I did suspect there was a second underlining fault as the heater seams to cycle in and out, more off than on. When on, the heater is at full temp (element has been replaced in the past). The red button on the safety thermostat hasn’t tripped. What do you recon mate? Has the earlier overheating due to the faulty capacitor cooked the safety thermostat or one of the remaining other two thermostats? If one of the thermostats were blown and producing an open circuit then surely the heater would never come on would it? Any guidance would be greatly appreciated Paul….best regards, Mark.
Hi, hope you can help me I have a Hoover condenser dryer model VTC791NB, the dryer will not heat up the filter condenser unit was covered in fluff, I have cleaned it out with an air hose and water is empty have I tripped it and if so is there a reset button, the drum goes round but the heater isn’t heating?
Many thanks Vanessa
