Solenoid coil inner diameter 14mm height 41mm engineering machinery accessories

Before servicing the solenoid coil, a preliminary diagnosis is required to confirm the fault. This includes checking whether the power supply is normal, using a multimeter to test whether the resistance value of the coil is within the normal range, and observing whether the coil has obvious physical damage, such as burning, breaking, etc. At the same time, it is also necessary to verify that the control signal is accurately transmitted to the coil. Through these steps, you can initially determine whether the coil itself is faulty, or due to the power supply, control signals or external environmental factors caused by the problem. Once it is confirmed that the coil is faulty, you can proceed to the next step of the repair process.
