Before assuming that your kitchen cupboard light is broken, make sure to check the power source. The light may not be working because it is not receiving power. Start by checking if the light switch is turned on and if the circuit breaker has not tripped. If everything seems to be in order, try plugging in another appliance to the same outlet to see if it is working. If not, then the problem lies in the power source and not the light itself.1.
