Maintenance of common faults in electric heating industrial cooking mixers
 
Common faults of the electric heating industrial cooking mixers are that after the electric cooking mixers is connected to the power supply, the temperature rises very slowly, and the dishes are difficult to cook. After the electric heating industrial cooking mixers is energized and the knob is turned, the inside of the pot is always not hot and the indicator light does not light up. The most common failure of the electric heating industrial cooking mixers is the damage of the electric heating element in the electric heating plate. Next, let's take a look at the troubleshooting methods of the electric heating industrial cooking mixers.
 
[Example 1] Trouble phenomenon: After the electric heating industrial cooking mixers is connected to the power supply, the temperature rises very slowly, and the dishes are difficult to cook.
Maintenance: The reason for this failure is that for the bimetallic temperature-regulating electric frying pan, except for the low temperature regulation or poor contact of the heating wire, the temperature regulator failure is more common, and it should generally be replaced at this time. In this case, it is a thyristor temperature regulation type. It has been investigated that the insulation of the capacitor c has decreased, which causes the charging to be slow and the vs cannot reliably trigger the conduction, and the heating is very slow. The heating is normal after replacing c. If the potentiometer rp is in poor contact, this fault will also occur.
 
[Example 2] Fault phenomenon: After the electric heating industrial cooking mixers is energized and the knob is turned, the inside of the pot is always not hot, and the indicator light does not light up.
Analysis and maintenance: At first glance, it seems to be a phenomenon of power failure. First check the contact between the power cord and the power connector, etc., basically good, no disconnection. The electric heating industrial cooking mixers also uses thyristor to adjust the temperature. Check each device with a multimeter. It is found that the trigger diode is open and damaged, so that the thyristor cannot get the trigger voltage and always cut off. The electric heater does not generate heat and the indicator light does not. Bright. After replacing the trigger diode with 0.5w/20v, the electric heating industrial cooking mixers returned to normal. In addition, if the bulb is open circuit or: eh open circuit (more common), vs open circuit will cause this fault.
