If the steamer does not heat, you need to replace the heating strip or check for circuit problems. The heating strip is a wearing part, and it should be eliminated first if there is a fault. Then check whether the line and power supply voltage are normal, whether there are any virtual connections and breaks in the line, and whether there are any problems with relays and contactors.

Troubleshooting method for steamer not heating.

The steamer does not heat. It is estimated that the heating strip is malfunctioning. The heating strip is a wearing part, and it should be removed first when the bun machine is not heating. If it is normal, check whether the power supply voltage is normal and whether there are any virtual connections and open circuits in the line, such as whether there are problems with relays and contactors. There must be a short circuit in the line.

The electric steamer does not generate heat when it is powered on, and the heating tube is also good. If this happens, first turn on the power, and then use the AC voltage level to measure the voltage at both ends of the heating tube. If there is voltage, it should be hot. If there is no voltage, check whether the wiring under the switch is open.

Heating tubes are made by installing electric heating wires in seamless metal tubes, such as carbon steel tubes, titanium tubes, stainless steel tubes, and copper tubes. The gaps are filled with magnesium oxide powder that has good thermal conductivity and insulation. It is made and then processed into various shapes required by users.
