When I turn on the air conditioning the light in my house goes out.
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?
Is the "lights" fuse blowing (or "lights" circuit breaker tripping) in the house power box?
Was the A/C properly connected to its' own fuse in the power box?
Does the A/C also cut out when the lights cut out?
