1炸炉
Gas Fryer		小火留不住/
小火突然熄灭
the small flame cannot be retained or suddenly extinguished		热电偶
Thermocouple		万用表
multimeter		1.排查气压是否在规定范围（液化气：1600-1800Pa；天然气：2400-2600Pa）；Check if the gas pressure is within the specified range（LPG：1600-1800Pa；NG：2400-2600Pa）
2.小火火焰是否完全包裹探头；Check if the small flame completely covers the probe
3.热电偶表面是否脏、氧化；Is the surface of the thermocouple dirty or oxidized
4.打开安全阀连续按住 30–60 秒再松手，让热电偶充分受热；万用表打到600毫伏档，万用表正负极分别接触限温器两个螺丝，查看读数，数值在450-580毫伏，热电偶正常，低于200毫伏为不合格；Open the safety valve and hold it continuously for 30-60 seconds before releasing it to allow the thermocouple to fully heat up，Set the multimeter to 600 millivolts, with the positive and negative poles of the multimeter touching the two screws of the temperature limiter respectively. Check the reading, and if the value is between 450-580 millivolts, the thermocouple is normal. If it is below 200 millivolts, it is considered unqualified.
5.检查线路的接触点是否有松动或者是否有脏污氧化现象，有以上现象要及时拧紧与清洁。Check if the contact points of the circuit are loose or if there is any dirt or oxidation. If there are any of the above phenomena, tighten and clean them in a timely manner.

安全阀
Safety valve		木棍 wooden stick如热电偶正常，小火还留不住，就是安全阀接收到电信号没有打开，有可能是阀卡滞导致无法正常打开，用木棍轻敲安全阀壳体后松开按钮，观察小火是否能正常保持，如不能就证明安全阀坏，需更换。If the thermocouple is normal and the small flame cannot be retained, it means that the safety valve has not received an electrical signal and has not opened. It is possible that the valve is stuck and unable to open normally. Use a wooden stick to lightly tap the safety valve housing and release the button to observe whether the small flame can be maintained normally. If not, it proves that the safety valve is broken and needs to be replaced.

限温器
Temperature limiter		万用表
multimeter		万用表打到蜂鸣档，万用表正负极分别接触限温器两个螺丝，查看是否导通，如导通则限温器提前介入需更换，反之，限温器正常；Set the multimeter to the beep mode, and contact the positive and negative poles of the multimeter with the two screws of the temperature limiter to check if they are conductive. If they are conductive, the temperature limiter will be activated in advance and needs to be replaced. Otherwise, the temperature limiter is functioning properly.

visual inspection		1.检查温控探头是否有油污覆盖或者温控探头接触到火管，如出现上述现象刮除探头表面油垢、焦渣，重新卡紧固定，保证探头悬空；Check if the temperature control probe is covered with oil or if it comes into contact with the fire tube. If any of the above phenomena occur, scrape off the surface oil and coke residue of the probe, re tighten and fix it, and ensure that the probe is suspended.
2.从最低温→最高温来回拧十几圈，把阀芯内部卡滞的油泥、杂质磨松；Twist back and forth from the lowest temperature to the highest temperature for more than ten turns, and loosen the oil sludge and impurities stuck inside the valve core.
3.上述操作都以完成，大火还是无法打开需更换温控器.All the above operations have been completed. If the fire still cannot be opened, the thermostat needs to be replaced
