7.2 The soleplate does not heat
If an iron doesn’t work, it may be due to the following causes:
7.2.1 Cut heater
In order to detect if the resistance is cut or not, the method to follow
involves the use of a tester between the two contacts of the resistor to
measure the continuity. If the heater is cut, change the base.
7.2.2 Defect in the bimetal or the thermostat
These irons don’t have an independent thermal fuse, but a re-settable
bimetal that is integrated in the thermostat. Check for continuity
between the terminals of the thermostat/bimetal and if there is no
continuity at ambient temperature, adjust the thermostat set or change
it.
7.2.3 Dirt between contacts
It might be the case that, by use, the iron will accumulate dirt in the lid
of the chamber. This dirt can enter between the thermostat contacts
and cause connection problems staying without closing the contacts
and therefore the iron doesn’t heat.
To check the problem, should close the thermostat and tested with a
tester the continuity between the terminals. If there is no continuity,
the problem is dirt and to alleviate it, clean the thermostat or replaced
it by another.
7.3 Fabric stuck to the soleplate
Fabric stuck to the soleplate is a symptom that the soleplate of the
iron has been at excessive temperature for this kind of fabric. This
excessive temperature can be due to two reasons: bad adjustment of
the thermostat, or wrong temperature selected by the user. To check if
it's a defect in the iron (thermostat), measuring the temperature in the
geometric center of the soleplate to position the regulator "max":
- If the max temperature is between 170-240ºC, the
behavior of the iron is correct. In this case, inform the user
that the clothes you must sort by type of fabric for ironing
them in different positions, as indicated by the labels.
Especially the synthetic and delicate materials must not be
ironed at high temperatures.
- If the max temperature is above to 240ºC, change the
thermostat and adjust correctly.
To remove fabric stuck to the soleplate, try to remove the residue with
a cloth fabric, with the sole hot. If this is not possible, change the
soleplate.
