Query: Almost started a fire

I use the timer for my air conditioner (the apartments all have old ones with no timers) so that my cats can stay cool during summer. Luckily, yesterday I was home and the air conditioner didn't come on. I checked the timer and the everything was frozen like cement. I pull it out of the wall socket and it is totally melted in the back. I had to pry the air conditioner plug out of it. I had a second one but it wouldn't work at all. I bought these things 2 years ago and they are only used for the 3 months of summer.Thinking of getting a heavy-duty outside timer and use it inside for the A/C. Perhaps one with a breaker switch inside of it if too much power is drawn. I check the A/c with Kill-A-Watts and it is within specs for this timer.
