Hotpoint tumble dryer not heating but drum still turns
Hotpoint NTM1192SK condenser dryer runs fine and the drum spins, but clothes come out cold and damp after a full cycle. Emptied the water tank and cleaned both filters. Could this be a thermal cut-out or the heater element gone? Roughly what should a repair cost?

If the drum is turning normally but there’s no heat, your checks so far are the right starting point. On this Hotpoint condenser model it could be a heater circuit fault, but it’s also worth ruling out airflow and control issues first.
1. Isolate the dryer from the mains before removing any panels or inspecting internal parts.
2. Check airflow thoroughly: - Clean the door filter and condenser/filter assembly again, including any fluff packed behind it. - Make sure the condenser area isn’t blocked and that air can move properly. Poor airflow can cause overheating and trip a thermal safety device.
3. Confirm whether there is any heat at all: - Run a timed cycle for 10–15 minutes and check if the air inside is even slightly warm. - If completely cold throughout, the heater circuit, thermal cut-out, wiring, or control side becomes more likely.
4. Thermal cut-out or heater: - Yes, a failed heater element or an open thermal cut-out/thermostat are common causes. - On some dryers the thermal device trips because of restricted airflow, so replacing it without fixing the cause can lead to repeat failure.
5. Also check for signs of water/condensation issues: - If it’s a heat pump variant rather than a standard condenser heater setup, diagnosis is different and may involve sensors, compressor, or control faults.
6. Rough repair cost in the UK: - Thermal cut-out/thermostat fault: often around £90–£160 fitted. - Heater assembly fault: commonly £120–£220 fitted. - If it’s a heat pump/refrigeration system issue, costs can rise significantly and may not be economical.
If you’re not confident with electrical testing, it’s best to get a qualified appliance engineer, especially for mains wiring or any sealed refrigeration work. If you can confirm whether the machine is completely stone cold or slightly warm, that would narrow it down further.

Safety first — read before actioning advice
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional — do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts are full of sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you're not confident testing or working inside the appliance, STOP and call a professional.
