How to check a solenoid valve?
Use the multimeter to check the impulse voltage and adjust the multimeter functional button to the AC gear, 50V. Use the black instrument testing pen to touch the N wire, and use the red instrument testing pen to touch the mainboard to output the signal terminal of the solenoid valve. Under general conditions, the mainboard will provide the solenoid valve with an impulse signaler at the 15th second (which is decided by the requirements of various refrigerator plants but mostly falls within the scope). The output length of the impulse signal is decided by the mainboard design app. When the signal is output, the multimeter hand will sway to the left for seconds. If the hand does not move, it means the mainboard has faults rather than the solenoid valve has faults.

What is the difference between a solenoid and an electromagnet?
For you not to mistake a solenoid for an electromagnet, the significant difference between both is that solenoids are wires coiled, but not around a metal core. Meanwhile, electromagnet’s wires are coiled around a metal core, in which the amount of current applied on them determines the strength of the magnetic field.

Why turn off the power when testing a refrigerator?
In this case, when you're testing a refrigerator start relay, you want to turn off the power both to prevent electrical shock and because the compressor could start at any time during the testing process, altering your results.
How to check if a relay is working?
Find the "s" and "m" plug-type terminals and the "L" slip-on terminal. Position the relay on the floor, counter or table so the "s" and "m" terminal are facing down. Insert the multi-tester with one probe on each of the "s" and "m" terminals. Set the tester to zero ohms. Turn over the relay and after a clicking sound, the reading should change to "infinity" if the relay is functioning. Turn the unit over again and place one probe from the "s" terminal to the "L" terminal. The tester should read "zero" again and when the relay is turned over, there should be no change in the reading if the unit is working properly. If it isn't, you'll need to replace it.
How to remove a wire-wound relay?
Inside the box is the overload protector, and the start relay. The biggest component is the start relay. A wire-wound relay can be tested by a do-it-yourselfer but a solid-state one will require testing by a professional. Pull off the wire-wound relay with needle-nose pliers.
