So I bought my parents a new microwave (old one was 23 years old, no turntable, burned half of everything with other half frozen), that I had to fit in the old trim kit. It's a close fit, but there's about a 2 inch gap + about 2 or 3 inches of trim kit.
I tested the microwave for ventilation by running it for 10 minutes to cook my lunch. Steam was coming out the cracks on the bottom and I could feel the high heat sticking my hand into the gap on top, so I figured the best solution would be to build a custom grille with some 60mm fans to help pull the hot air out. I need it to do this:
-Fans turn on only after a certain temperature is reached at the microwave exhaust.
-Microwave remains plugged in 24/7.
My thoughts on equipment:
-Temperature sensor switch that provides power to fans after a set temperature is reached
-System uses standard electrical outlet
What kind of equipment would I need to achieve this?
