Your Condenser tumble dryer is not heating? It Could Be One Of The Following:

  1. Heater fault.
  2. Cut out Thermostat faulty (TOC Thermal Overload Cut-out)
  3. Cycling Thermostat faulty
  4. Ntc fault if fitted faulty
  5. Air flow temperature thermostat faulty
  6. Pcb if fitted

Condenser dryers can be installed without the requirement to have a vent to the outside. However, it should be noted that these cannot be installed just anywhere and there are restrictions on temperatures and that cleaning filters regularly becomes essential. The moisture removed from the clothing during the drying process is condensed internally and the water vapour either drained to the house drainage system or collected in a container which has to be manually emptied.

low heat can be caused by one side of the heater not working or air flow problems

Thermostats & heater elements can be simply tested for continuity using an electrical meter. If the heater is open circuit it will require to be replaced, bearing in mind that many are in fact two elements for the different levels of heat, so check both circuits. If the heater is not open circuit and you have continuity then you should then look at the thermostats. Normally there are one of possibly two mounted around the heater housing but there are also often another one, possibly two, hidden on the vent or front of machine as you will see in this video there is one hidden in the drum, this is commonly known as the "exhaust stat" Air flow temperature thermostat.

Ntc sensors can be tested by using charts to measure resistance compared to the temperature see other videos on this.
