Iron not heating
Iron turns on but stays cold, only reaches a low temperature or no longer produces steam? The most common culprits are a bimetallic thermostat with welded contacts, a broken nichrome heating coil, a blown thermal fuse, a limescale-clogged steam-station boiler, or an internal cord break where the lead enters the iron. We measure every point in the heating circuit, compare the readings against factory resistance values, and agree the estimate before ordering any parts.
An iron is one of the most frequently used household appliances, and inside it high temperature, water and electricity come together — which is exactly why faults can be both inconvenient and dangerous. We work with all popular brands — Philips, Tefal, Braun, Bosch and Rowenta. Every iron is diagnosed methodically: we measure heating element resistance, check thermostat and fuse contacts, test the power cord from plug to terminal block, and visually assess limescale deposits in the steam generator. We always agree on the cost before starting work, and if you decide not to proceed we return the appliance with no obligation. All repairs carry a 3-month warranty.
Likely causes
- Thermostat failure — The bimetallic thermostat regulates the heating element temperature. If the thermostat contacts have burned out or fused together, the iron either does not heat at all or heats uncontrollably. A faulty thermostat can be detected with a multimeter by measuring contact switching.
- Heating element burned out — The nichrome heating coil oxidises over time and can break. The iron turns on, the indicator light is on, but the soleplate stays completely cold. A resistance measurement shows infinity — the element is open-circuit and needs replacing.
- Thermal fuse blown — The safety thermal fuse blows if the iron overheats due to a thermostat malfunction. Once blown, it completely breaks the heating circuit — the iron will not turn on or turns on without heating. Replacement is mandatory, and the thermostat must also be checked.
- Steam generator boiler calcified — In steam station irons, the boiler gradually fills with limescale deposits that block the heating element and reduce steam output. The boiler can overheat and trip the thermal fuse. Professional descaling or boiler replacement is needed.
- Power cord internal break — An iron cord is constantly flexed and pulled. The internal copper conductor can break at the entry point into the iron or at the plug, creating an intermittent connection. The iron works erratically or does not turn on at all. Cord replacement restores stable power.
Try this first
- Test the wall outlet with another appliance — make sure the problem is in the iron, not the mains.
- Set the temperature dial to maximum and wait 3–5 minutes — sometimes the thermostat does not engage at low settings.
- Gently wiggle the power cord where it enters the iron — if the iron starts and stops, the cord is damaged.
- For steam stations — check that there is enough water in the boiler tank and that the leak indicator is not active.
When to bring it in
If the iron does not heat even on the maximum setting, gives off a burning smell, the cord is visibly damaged or the steam station has stopped producing steam — bring it in. Do not attempt to open an iron yourself unless you are a qualified technician — exposed mains-voltage parts inside present a serious shock and fire hazard. We will diagnose and repair it with a 3-month warranty.
