How to check a solenoid coil with a multimeter?

You can check solenoid coil resistance using a multimeter by following these simple steps:

1. Remove the solenoid coil from the system if possible.
2. Connect the solenoid to a power source. You should hear a click of the valve plunger moving in response to the current. If you don’t, the valve is broken.
3. Set your multimeter to ohms (­ꭥ) to measure the resistance of your solenoid coil.
4. Touch the multimeter’s red cable to the positive terminal of the solenoid, and the black cable to the negative terminal.
5. Check the reading on the multimeter. It should read between 0 and 1ꭥ. Any other reading indicates that there is too much resistance in the solenoid coil system, impeding the current’s flow.
6. The solenoid will need replacing if resistance is higher than 1ꭥ.
