Increase knowledge! Common faults and basic troubleshooting methods for gas stoves

Everyday, three meals a day can not be separated from the kitchen, but in the kitchen cooking can not be separated from the gas stove, if the gas stove has a problem, what should we do? What should I do with some common problems? Below we summarize the common faults and troubleshooting methods for gas stoves. I hope that after seeing this article, consumers will not be so blind after encountering the problem of gas stoves.
       Increase knowledge! Common faults and basic troubleshooting methods for gas stoves
       Common faults and troubleshooting methods for gas stoves are:
       1. Gas stove leaks or smells gas
       The cause of the failure: the rubber tube aging is broken or not connected; the gas cooker does not burn when it is ignited; it is blown out by the wind or drained by water during use; the igniter gas pipe leaks, the cylinder valve, the pressure reducing valve or the gas furnace leak gas.
       Maintenance method: the rubber tube should be replaced or re-connected; the gas should be re-ignited after the gas is blown away; if the flame of the gas stove is blown out by the wind or is extinguished during use, the switch should be closed, and then the gas is blown off and then ignited; Replace the igniter gas pipe; find that the gas cylinder valve, pressure reducing valve or gas furnace leak should be sent to the professional maintenance department for repair or replacement of new products.
       2, the gas stove does not catch fire
       The cause of the failure: the combustion gas in the liquefied gas cylinder is used up or there is no combustion gas in the pipeline; the air is mixed into the gas pipeline; the rubber hose of the gas transmission is twisted, flattened and blocked; the igniter electrode or the air guide of the gas stove Too dirty; the ignition nozzle or the burner nozzle is clogged; the distance between the discharge needle and the air guide groove is improper; the piezoelectric ceramic is damaged.
       Maintenance method: the gas cylinder should be replaced or the gas supply should be inquired; the ignition can be repeated several times to eliminate the air inside the tube; correct or replace the gas hose; wipe the igniter electrode or air guide with a dry cloth; In the burner, use a 0.4MM thin wire to insert the nozzle hole to remove the dirt; adjust the distance between the discharge needle and the bracket to the appropriate position, generally 3-4MM; if the piezoelectric ceramic is damaged, replace the new piezoelectric ceramic.
       3, the flame burning of the gas stove is not normal
       Cause of the malfunction: improper air conditioning; the stove or the cooktop is not covered; the burner flame is blocked or improperly installed; the air supply pressure is insufficient or excessive; it is disturbed by the environment or convective air.
       Maintenance method: use qualified liquefied petroleum gas products or adjust the gas volume to prevent tempering; try to maintain normal gas supply pressure; often clear the nozzle and adjust the amount of combustion air; if the temperature of the burner head increases, the flame The propagation speed increases and causes tempering. It can be suspended for a while, and then used after the burner is cooled. Correct the gas nozzle center line or replace the nozzle; often clear the fire hole and mixing tube; replace the old burner on schedule.
       4. During the working process of the gas stove, the flame leaves the burner exit and burns outside a certain distance (also known as the flame).
       The cause of the failure: the gas pressure is too high; the amount of combustion air is too large; the air around the burner flows too fast, causing the flame to float away from the fire orifice.
       Maintenance method: adjust the gas switch to reduce the flow rate to reduce the gas pressure; adjust the combustion air flow, seal a part of the air inlet with a tape; use the windshield to control the surrounding air flow interference.
       5. When the gas stove is working, the flame is yellow and black, and the bottom of the pot is carbon.
       The cause of the failure: insufficient oxygen content in the surrounding air; the air around the gas stove is flowing too fast; the gas stove nozzle and the mixing tube are not centered; the gap between the inside and outside of the burner of the gas stove is blocked, and the gas stove is insufficient when working; the gas stove The burner design is unreasonable.
       Maintenance method: strengthen the kitchen ventilation; control the air circulation around the gas stove; correct the position of the gas stove nozzle and the mixing tube; remove the blockage of the flame ring inside and outside the gas stove burner; replace the burner of the gas stove.
       6. When the gas stove is ignited, there is no spark or spark, but there is no point.
       The cause of the failure: The ignition device of the gas stove is a piezoelectric ceramic. After being used for a long time, the metal rod in the ignition device is contaminated and rusted, resulting in poor contact, resulting in a "beep" sound during ignition, but no Sparks are produced.
       The maintenance method extracts the metal core rod in the piezoelectric ceramic, polishes it with fine sandpaper and inserts it into the piezoelectric ceramic to ensure that the core rod and the piezoelectric ceramic are in good contact, and the normal ignition can be resumed. If the positive electrode of the piezoelectric ceramic is broken, connect the wire.
       7, gas stove automatic ignition device can not emit sparks
       (1) Cause of failure: The circuit of the gas stove has a broken circuit. Because the connection of the piezoelectric anti-theft intermediate metal round bar of the gas stove is to use the gap between the metal filaments of the inner core of the wire, the metal circle is inserted into the pointed shape. Baton. The connection method is easy to loose, causing the resistance value of the contact point to increase and heat, and the high temperature generated by the piezoelectric ceramic inherently high temperature, easily burns the plastic outer skin of the wire, and the thin wire of the inner core of the wire is naturally loose due to lack of fastening force. Then, the connection with the piezoelectric ceramic intermediate metal round bar is loosened, causing an open circuit.
       Maintenance method: If the original length of the gas stove has a sufficient length, the burned line segment can be cut off and inserted, and it can be repaired.
       (2) Cause of failure: The metal round bar is in poor contact with the piezoelectric ceramic. If the gas stove is used for a long time, the metal round bar can not be sparked when the contact is poor due to dirt, rust and the like which are overflowed on the gas stove.
dimension        Repair method: Pull out the metal round rod in the piezoelectric ceramic, and clean the dirt with the zero-number sandpaper before inserting it, so that it can be in good contact with the piezoelectric ceramic.
