A few weeks ago I bought an air conditioner, but if I have it on for several hours (8 hours on average), the light in the bulbs (not the sockets) cuts out. ¿What is the problem?

Was this a window unit? How many AMPS does it draw? Check the circuit breaker fuse for the rated amount of amperage. Hold the cord and see if it is warm or hot. What else is drawing current on the same circuit?
