A relay is just a switch in what way it is faulty? Better check with a technician as to measure coil voltage, resistance, continuity. It can be anything from oxidation, a bad transistor, bad cap, bad diode, bad joint. Relays are cheap (labour is not) if you want to replace but inspect all other things first.
