The original Miele 5432491 safety thermostat is a Klixon type temperature limiter that protects the heating element in the tumble dryer from overheating. The component operates at 175°C and is suitable for conventional tumble dryers and heat pump dryers. The part replaces part numbers 5432490, 5126720 and 4710950.

The dryer stops heating in the middle of a cycle? The laundry comes out damp even though the dryer has been running? The safety thermostat may have tripped due to overheating and burned out. This is one of the most common parts to replace in Miele dryers – and with a genuine part, the dryer will be back to normal.

A moment before ordering – safety above all! To ensure a successful repair and maintain the longevity of the device, it is mandatory to use only original parts. Non-original parts may disconnect at the wrong temperature and endanger the device. Now click the 'Check Model Compatibility' button at the top of the page and our system will immediately confirm that the part is suitable for you.

What are the signs that the safety thermostat needs replacement?

A tripped safety thermostat permanently disconnects the heating circuit. The dryer continues to operate – the drum is spinning, the program is running – but with no heat at all. The laundry comes out just as damp as it went in.

Common signs:

✅ The dryer works but does not heat on any program ✅ The laundry comes out damp after a full cycle ✅ The dryer stopped in the middle of a cycle due to overheating ✅ A heating-related fault code appears on the control panel

From the experience of our technicians, approximately 70% of cases in which a Miele dryer stops heating end with replacing the safety thermostat only - without further repairs.

Why was the thermostat turned on in the first place?

A tripped safety thermostat is always a sign that something has caused the overheating. Common causes: a clogged Malamute filter, a blocked exhaust pipe, or poor ventilation. Before replacing the thermostat – it is imperative to locate and resolve the original cause , otherwise the new thermostat will burn out again in a short time. A qualified technician will diagnose the cause and replace the part in one visit.

Why only a genuine Miele part?

A non-original thermostat may cut off at the wrong temperature – too low will cause unnecessary frequent cut-offs, too high will allow overheating and endanger the heating element. The original part is precisely calibrated to 175°C exactly as Miele requires.

Where is the model sticker on a Miele dryer?

🔧 Can I replace the thermostat myself?

⚠️ No. Replacing a safety thermostat requires partial disassembly of the dryer and access to an internal electrical component that operates on mains voltage. Installation by a person who is not a qualified technician is life-threatening and voids the warranty.

In addition – as noted above – before replacing, it is necessary to locate the cause of the heating. A qualified technician will perform:

1. Diagnosing the cause of thermostat activation – filter, exhaust pipe, ventilation
2. Cleaning or repairing the original cause
3. Dismantling the panel and locating the thermostat on the heating element
4. Disconnecting and replacing the new component with Faston connections
5. Checking for integrity before reassembly

💡 Tip from the experts

Based on thousands of service visits we have made: The number one cause of a safety thermostat tripping on Miele dryers is an uncleaned Malamute filter. A clogged filter prevents proper airflow – heat builds up in the drum and trips the thermostat. Cleaning the filter after each cycle can completely prevent this problem.

💡 Insight from the field: The dryer's exhaust pipe also requires an inspection once a year. A long or folded pipe adds resistance to the airflow and doubles the risk of overheating. A technician who comes to replace a thermostat always checks the pipe route as well - it's worth asking for it explicitly.

❓ Frequently Asked Questions

Can the thermostat be reset instead of replacing it?

No. The Klixon thermostat with a normally closed (NC) is a one-time component. Once activated, the electrical circuit is permanently open and cannot be reset. The entire component must be replaced.

What is the difference between SKU 5432491 and 5432490 and 5126720?

The three part numbers are different versions of the exact same component – ​​a 175°C safety thermostat with 6.3mm Fastons. 5432491 is the most updated part number that replaces the previous ones. If you have the old one on your parts list, order 5432491 – it sits in the exact same spot.

After replacing the thermostat, the dryer still doesn't heat - what's the reason?

If the thermostat has been replaced but the dryer still does not heat, the cause is probably one of three: the heating element itself has burned out, the control board is faulty, or the cause of the overheating was not addressed before replacement and caused the new thermostat to burn out. Contact a technician for re-diagnosis.
