Can a relay cause AC not to work?
If the relay gets stuck in one position, it can prevent the air conditioner from turning on or cause it to turn off unexpectedly since the ac fan and blower motor won’t receive the necessary power to operate. A faulty relay is the main cause of electrical power problems with your HVAC unit.
What happens if AC relay goes bad?
Another indication that your AC relay has probably failed is that there will be no cool air supply at all from the air conditioner unit. If the compressor relay fails, the compressor responsible for circulating cool air will not function. Hence, the air conditioning system will be incapable of producing any cool air.
