Jack error codes for all models<\/a> help you tell a board fault from a motor fault.<\/p>\nSewing Machine Motherboard FAQ<\/h2>\nWhat is the price of a sewing machine motherboard in India?<\/h3>\n
Main PCB control boards in our catalogue cost between \u20b91,500 and \u20b94,650, depending on the machine. Jack A2B is \u20b92,900, Jack 781G is \u20b94,650 and Qi Xing QD8633 is \u20b93,100. Display panels and pedal boards cost less, from \u20b9300. Prices on this page are live catalogue prices and COD is available.<\/p>\n
How do I know which PCB fits my sewing machine?<\/h3>\n
Match the part number printed on your old board, not the machine's looks. Then compare the connector layout and the voltage rating, and check whether your board is an old or new type. Our stock list above shows the part number for each board, so you can compare it before ordering.<\/p>\n
Can I use a universal or generic PCB instead of the original?<\/h3>\n
A universal board works only where its connector layout and functions match your machine, for example the direct drive servo control board for servo motors. For machines with auto trim and sensors, a model-specific board is safer, because a generic board may not drive every function.<\/p>\n
How do I know if the PCB is faulty and not the motor?<\/h3>\n
If the motor runs only at full speed, stops at random, or ignores the pedal while the pedal and wires are good, the board is the usual cause. If the machine has no power at all, check the plug, fuse and power cable first. When in doubt, send us the symptoms and the machine model.<\/p>\n
Are Jack A2B and Jack A2C PCBs the same?<\/h3>\n
No, treat them as different boards. Jack A2B uses part number 19510031200, while the A2-CZ board uses 9950014900. Both are in stock here, so compare the number on your old board before you order. Do not swap them just because both belong to the A2 range.<\/p>\n
Do you deliver sewing machine motherboards across India with COD?<\/h3>\n
Yes, we ship pan-India and COD is available on these boards. Check the product page for the live price and stock status before you place the order, since stock changes through the day.<\/p>","parent":0,"count":40,"filter":"raw","image":""}],"product_tag":[{"term_id":3350,"name":"5V_PEDAL_V1.1","slug":"5v_pedal_v1-1","term_group":0,"term_taxonomy_id":3350,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2129,"name":"direct drive sewing machine parts","slug":"direct-drive-sewing-machine-parts","term_group":0,"term_taxonomy_id":2129,"taxonomy":"product_tag","description":"","parent":0,"count":10,"filter":"raw","image":""},{"term_id":3353,"name":"foot pedal sensor board","slug":"foot-pedal-sensor-board","term_group":0,"term_taxonomy_id":3353,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3358,"name":"Hall sensor pedal PCB","slug":"hall-sensor-pedal-pcb","term_group":0,"term_taxonomy_id":3358,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3169,"name":"industrial sewing machine spare parts","slug":"industrial-sewing-machine-spare-parts","term_group":0,"term_taxonomy_id":3169,"taxonomy":"product_tag","description":"","parent":0,"count":15,"filter":"raw","image":""},{"term_id":3357,"name":"lockstitch machine spare part","slug":"lockstitch-machine-spare-part","term_group":0,"term_taxonomy_id":3357,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3349,"name":"Maqi Q3 pedal board","slug":"maqi-q3-pedal-board","term_group":0,"term_taxonomy_id":3349,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3348,"name":"Maqi Q3 Pedal PCB","slug":"maqi-q3-pedal-pcb","term_group":0,"term_taxonomy_id":3348,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3354,"name":"Maqi Q3 spare part","slug":"maqi-q3-spare-part","term_group":0,"term_taxonomy_id":3354,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3355,"name":"Maqi Q5 PCB","slug":"maqi-q5-pcb","term_group":0,"term_taxonomy_id":3355,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3359,"name":"pedal controller board","slug":"pedal-controller-board","term_group":0,"term_taxonomy_id":3359,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3352,"name":"pedal speed controller PCB","slug":"pedal-speed-controller-pcb","term_group":0,"term_taxonomy_id":3352,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3356,"name":"Q3-M pedal PCB","slug":"q3-m-pedal-pcb","term_group":0,"term_taxonomy_id":3356,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3288,"name":"sewing machine electronics","slug":"sewing-machine-electronics","term_group":0,"term_taxonomy_id":3288,"taxonomy":"product_tag","description":"","parent":0,"count":2,"filter":"raw","image":""},{"term_id":3351,"name":"sewing machine pedal PCB","slug":"sewing-machine-pedal-pcb","term_group":0,"term_taxonomy_id":3351,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""}]},"yoast_head":"\n
