my zanussi tumble dryer has had all new parts fitted by an engineer but is still not drying properly,
i have noticed that the heater comes on for a few seconds then goes noff again this is repeated throughout cycle... all heaters have been replaced even sensor .. any ideas?

Is the engineer aware of this fault?.Get him back in and explain your findings.providing the dryer is not clogged with lint,he can bypass the thermister to check its operation.Even new T/stats can be faulty,.He will now know if there is a problem with the heater relay on the pcb.A new pcbcosts around £100 or you can by a reconditioned unit for around £40 its a exchange service.
