1, electric pressure cooker pot leakage around the repair

The emergence of such a failure, first check whether the liner flap deformation, resulting in poor sealing. If the liner flap is deformed, slight deformation can be corrected with tools, serious deformation requires replacement of the liner. If the inner liner flap is not deformed, then check whether the relative height of the liner and the inner cover is low, resulting in poor sealing (use vernier calipers to measure the height of the liner edge to the edge of the inner cover, if it is less than 12mm, it means that the height is not high enough, you can put a piece of spacer on the three feet of the disc spring on the heating plate, so as to achieve a relative height of 12 -13.5mm). If it is not low, check if the sealing ring is broken or if there is any foreign matter adhering to it. If so, check for uncleanliness or damage and replace the seal if found; if there is no damage or foreign matter adhering to the seal, check whether the steel ring is deformed, the seal is assembled in a shifted position, or the seal is not assembled in place and forced to close the cover.

This kind of failure, first check the pressure limiting valve, float valve, steel ring, the inner liner is deformed. If there is no deformation, then check whether the timer starts when the pressure switch is off. If the timer starts, use a thermometer to check whether the temperature inside the pot is within the specified range when it is kept warm. If the temperature is within the range, check whether the heating plate is deformed, resulting in high upstroke pressure. If there is no deformation, check whether the starting pressure is too high.

The emergence of such a failure, the first check whether the starting pressure is too low. If the pressure is not too low, then check the holding time is too short. If the holding time is not too short, check the inner liner for deformation. If the liner is not deformed, check if the heating plate is deformed. If the heating plate is not deformed, check if the temperature limit is too low.

4, the electric pressure cooker after turning on the power to keep warm, can not be heated repair

This kind of failure, first check whether the heating plate is damaged. If the heating disk is not damaged, then check whether the fuse is damaged. If the fuse is not damaged, check whether the internal wire is disconnected. If the wire is not disconnected, check for damage to the thermostat. If the thermostat is not damaged, check if the insulator is damaged. If the thermostat is not damaged, check if the pressure switch is damaged.

5, electric pressure cooker to open and close the lid of the difficult repair

This kind of failure, the first check whether the lid is deformed or the inner cover is deformed. If it is not deformed, check whether the sealing ring is well installed. If not, check the sealing ring to see if it is well installed. If it is well installed, check the height of the inner pot relative to the inner cover to see if it is too high. If not, check if the push rod screw is too long. If it is not too long, check whether the connecting plate pusher is deformed. If it is not deformed, check if the base screw is tight.

6, electric pressure cooker press the control panel button does not work properly or the work of the light does not light up the repair

The main causes of such failures are whether the display board is damaged, the display board button or indicator lamp damage and poor contact with the internal wiring.

First of all, use a multimeter to detect the display board internal connection line access, and then test the display board keys and indicators, such as bad, then replace the display board keys and indicators, such as the display board is damaged, then replace the display board.

7, electric pressure cooker power on the control panel without display repair

The main cause of such failures is the internal power supply path, the power plug socket is not in good contact with the thermal fuse FU and thermostat is disconnected.

These failures are mostly caused by the in-house power supply, using a multimeter to detect the power plug and socket and the thermostat is poor contact. If normal, it is the fuse FU fuse, confirm the circuit without a short-circuit after the replacement of the fuse FU.

8, electric pressure cooker overhaul should pay attention to matters

Electric pressure cooker overhaul should pay attention to the following matters:

1) Measurement of the pressure switch to remember to disconnect the two ends of the connecting wire.

2) The rotation of the timer of the electric motor type is controlled by the pressure switch. When the timer does not turn, watch for a pressure switch failure or a leak in the pot itself that makes the pressure inside the pot insufficient to trip the pressure switch.

3) Adjust the pressure temperature control knob. According to the principle of thermal expansion of the contact patch, the pot pressure is too large is not good, it is recommended to fine-tune the water after the test pressure, counterclockwise rotation to increase the pressure in the pot, clockwise is to reduce the pressure.

4) The circuit board welding surface are coated with moisture-proof oil, so in the measurement need to ensure that the measuring tool can be good contact with the measurement point. However, you can not use sharp instruments to scrape and scratch the circuit board, so as not to cut the circuit board on the copper skin alignment. After replacing the device you need to re-brush the moisture-proof oil at the soldering point.

5) Welding devices need to use anti-static soldering iron, with anti-static hand ring.
