I installed a new patio light outside my carport door and it works but it feels a little too hot and right next to it is laundry room which has no power. I tried reset breaker nuthin and checked fuses they were fine. What could be wrong?

Heat is a normal by-product of electricity running through a light bulb. The worst offender is an incandescent light bulb.

The incandescent bulb heats a Tungsten filament which gives off heat.

That said, what type of bulb are you using? What is the amperage of the circuit and what is the AWG of the cable that connects to the lamp?

Where is the heat ?

You may have disconnected a circuit wire or interrupted it to get power for the light. How did you wire the light? New install or replacement?
