HEATING COIL
Outer part of the heating coil is made of stainless steel and inner part is made of heating coil wire and magnesium
oxide insulation. Heating coil flange includes heating coil, thermocouple pipe and anode bar mounting bracket. It can
be in different shapes and powers depending on the model. Mechanical thermostat, electronic thermostat and limit
thermostat thermocouples installed in thermocouple pipe must be secured to the deepest section and a rubber plug
must be mounted at the end to prevent them from falling.
Heating coil measurement method;
Move the level of your measurement device to Ω (ohm) position and measure the resistance. If you can read the
circuit as illustrated, then you need to check if there is any leakage to the body. Contact one of the probes to one
of the ends and other probe to flange gasket. If the value is shown, it is defective, if not it is intact.
