1. The knob itself (switch) is damaged or burnt out.
If the knob is damaged or burned out, it means that the circuit of the furnace cannot be connected and the temperature and power cannot be adjusted. Therefore, when the knob itself is damaged, it may be necessary to replace it with a new knob.
2. Circuit board failure
Commercial induction cooker's circuit board controls the operation of electromagnetic heating elements. If the circuit board is damaged or broken, the signal of the knob may not be transmitted effectively, resulting in the failure of the furnace. In this case, the circuit board needs to be repaired or replaced.
3. External connection failure of the line
The connection of line parts may also cause the knob to fail. Common causes include wiring errors and plug problems, such as poor plug contact. Correct wiring can solve these problems and restore the working state of induction cooker.
4. The power adapter is damaged
Power adapter is the power supply equipment of induction cooker. If the adapter is partially damaged, it may lead to unstable power supply or no power supply at all, thus affecting the operation of the knob. The solution in this case is to replace the appropriate power adapter.
When the commercial induction cooker knob fails, the following measures can also be taken to solve the problem:
1. Check whether there is a circuit switch tripping near the start switch, and reset it if it trips.
2. Check whether the line connection is reliable and the plug contact is good.
3. Check whether the rotating direction of the knob is correct. If the knob cannot be started when it is turned to the bottom, it may be necessary to replace the knob.
The best way is to seek the help of professional maintenance masters, so that they can detect problems and carry out maintenance. Commercial induction cooker is an important equipment, which is widely used in production and catering environment. Therefore, it is very important to keep it in normal working condition.
