Symptoms of a faulty relay board include:  

• Intermittent or unpredictable power level adjustments
• Magnetron fails to turn on or fluctuates excessively
• Light not illuminating properly  
• Fan speed irregularities
• Microwaves not properly heating foods

Causes can be damage from liquid intrusion, heavy usage over time stressing the relays, or component failures within the board itself.
