Vented tumble dryer not heating

[Fed]

Hi, I have a Zanussi ZDE47200W vented dryer that runs but doesn’t get warm. After taking the back off I see that the heater element initially gets hot and glows red for a few seconds and then goes cold and stays off.

I have replaced the heater and the heater Element sensor but the same thing happens.

any help or suggestions would be appreciated!

what do you call a few seconds ?

there are thermostats and sensors on the element that cut it out if things get too hot. without the cover in place it will overheat

with it all back together does it heat in timed mode ?

Hi Dave,

it’s about 5 to ten seconds. I have put the covers back on and it seems to be the same, although of course I can’t check but it doesn’t heat the drum.

Thanks

Sorry, missed the second part of your answer. I don’t think there’s a timed mode, only degrees of dryness on the rotary dial. Am I missing something?

also most later dryers wont heat unless there are wet clothes in as an energy saving feature which is why i said timed dry as somtimes its exempt

I have been testing it with wet towels in. Do you have any other thoughts?

Thanks

and timed drying ?

Dave

I’ll try it when I get home, thanks

It doesn’t heat on timed drying

next then you need to check the front temp sensor
take off right side its mounted in the fan chamber

at 20 degrees C you should get a resistance around 6000 ohms

Thanks Dave. Is that a different sensor to the heater element sensor probe as I’ve already replaced that one?

[electrofix]

yes different one. senses the air leaving the dryer

Dave

[Fed]

Ok thanks, will take a look. Have a good evening.

Just a thought i think there is a thermostat fitted at the front as you open the door the plastic that the door closes into there should be one there this maybe your problem

Thanks, I’ll take a look.

cheers
