Locate the electrical panel in your home. It is the panel that contains the circuit breakers and is likely located in a storage area of your home, such as the basement or garage.
Open the panel door and locate the delay circuit breaker. If it has been tripped there could be a red color on the switch.
Flip the switch to the "Off" position.
Flip the switch to the "On" position. If the delay circuit still isn't functioning it is likely faulty and will need to be completely replaced.
