Introduction

There is this great teardown guide for Philips Steam Iron:

Philips Pressurised Steam Generator GC8220 Teardown

If no Philips spare part is available to you, it can be replaced with a generic from electronics component shops.

My Philips GC 9245 after ironing found water on the shirts, and the iron heat is not like as hot as in the past, is this cause by the Temperature Sensor (NTC Thermistor) ?

With GC9220 model, résistance of boiler CTN : around 300k à 15°C, decreasing slowly to 160K at around 30°C, I didn’t test with other temperature.
