What s going on with the induction cooker function key not being able to adjust the gear?

Generally, in this case, the integrated circuit section of the touch button is broken and needs to be replaced.

But before you finally determine whether the induction cooker is broken, 1: Please check the power interface and socket first to see if it is normal;

2: The bottom of the induction cooker is ventilated before and after when it works, so the plastic film must not be padded below, and the induction cooker generally has automatic protection, that is, the ventilation is not normal and stops working, and the key function can not be switched at this time;

3: Send it to the maintenance point for inspection to see the real problem.

The induction cooker will often get water into the vegetable soup, and it will also malfunction after a long time. For example, the function keys are flickering and jumping, so what is the reason for this problem? Let's take a look with the home appliance expert Xiu Dada.

First, the function key of the induction cooker jumps randomly.

Phenomenon: The function light jumps randomly, the buzzer beeps, and the function buttons fail.

Second, the reason for the function key of the induction cooker to jump randomly.

Reason 1: The main reason is that there are deteriorated or virtual welded components in the machine.

1. Check whether the negative temperature detection resistance deteriorates, the thermostat on the furnace surface is 200 kohms, the heating resistance of the resistance can be smoothly reduced, the resistance value of stopping heating can return to 200 kOhms, and the IGBT tube thermistor is also normal 200 kOhms;

2. Check the comparator LM339 again, and the resistance value of each pin is measured on the road, and there is generally no abnormal phenomenon;

After repairing the welding of the components, the machine is turned on, and the fault is manifested as the constant temperature and firepower, the two display lights jump alternately, the functional temperature indicator is 120 degrees, and it jumps to 180 degrees for a while, and the buzzer follows the chirping, heating for nearly 10 minutes, and the induction cooker dies.

Cause 2: Caused by leakage of components.

1. Remove the control board pair, test several micro switches with buzzer stops, and find that SW4+ and SW3- are in poor contact, and the others are normal;

Replace the SW4+ and SW3- buttons, the fault still exists after powering on.

2. Soldering SW5, no abnormality with R 1K block measurement, abnormal when changing R 10K block measurement, the watch hand quickly points to 90 thousand ohms below and unstable, with the hand holding part of the temperature induction, the watch needle slides down to about 70 thousand ohms, with a soldering iron to add a little temperature to 50 thousand ohms, the watch needle is always unstable, but the button can be turned on to 0 ohms, and the watch hand is loose and the watch hand swings between 50 and 90 thousand ohms.

3. After replacing the new SW5, wait for half an hour to observe and turn on, all functions are normal, troubleshooting.

After powering up, stay in the fort soup key.

Bad contact, take it and fix it!

It should be broken, just find someone to fix it.
