1, the machine power on the electricity, but the machine as a whole no current. This may be due to the operation of the electric cake pan is too frequent, affected by high temperature, so that the machine inside the fuse melted, generally commercial electric cake pan is more often such a problem. We can go check to check the power supply, and then the fuse is replaced again.
2, the machine is on, but the heating speed is very slow, making snacks when the temperature is not uniform. It may be that some electric heaters inside the electric cake pan burned out, we have to remove the machine switch, change the heaters, and then adjust the voltage to keep the voltage in the most appropriate state, not too much voltage, the heaters burned out.
3, the machine will not operate after power on, other parts are no problem. Such a situation may be due to our use of electric cake pan did not pay attention to the standard operation, so that the switch inside the electrical components soaked in water, caused by the short circuit phenomenon. At this time we need to remove the electrical components of the natural air drying, so that the moisture completely dry and then put back to use.
4, after turning on the power, can not enter the working state, the indicator does not light
According to the analysis of the failure phenomenon, may be the power supply circuit failure. Check whether the power plug and socket contact is good, check whether the fuse is intact, and then measure the AC power supply for 220V, but measure the primary voltage of the power transformer for 0V. thus judging that the switch has a problem. Then check the relevant components, found that the switch contacts broken, resulting in the transformer can not access the AC power supply. Replace the switch, turn on the power supply, check the electric cake pan work normally, troubleshooting.
5, the temperature loss of control, can not be used normally
The cause of the failure has a variety of reasons, such as relay contacts sticking, transistor collector and emitter breakdown, dare to ask the element is damaged, thermostatic components are damaged or disconnected, diode internal breakdown of the short-circuit, the integrated circuit is damaged internally. The correct repair method is to repair according to the situation, otherwise, the situation may go wrong. If the circuit has been pierced, replace the same type of tube, etc..
6, power on, the function of the indicator is normal, but can not be heated
Analysis based on the failure of the phenomenon, may be the relay and heater circuit failure, first unplug the power supply, open the bottom cover of the electric cake pan, use a multimeter to measure the value of the upper and lower heaters of the DC resistance value, should be in the normal 45 megabytes or so. Measured no abnormality, indicating that the fault has nothing to do with the heater. Then check the DC relay, if there is a failure to repair in time. It is best to find a professional home repair, otherwise, the fault has been there, will cause adverse effects.
