Relay if it does not stay energized the thing being controlled will not work properly
Energize the relay an a set of contacts within the relay change their state from either on/off to off/on.
1- Does the relay itself work when energized, look, feel the relay, there is a clicking noise when it mechanically moves.
2- Do the contacts work, are N.O. contact open, are N.C. contacts closed when the relay is not energized.
3- Do the contacts change their state from N.O to closed and from N.C to open when the reay is energized
4- When energized does the relay work or just hums or nothing happens
5- Are the wires connected
6- Are the contacts in good shape, or worn, burnt
