HI ALL,
I have an air conditioner with removed electronics. I can manually control the compressor and blower easily enough, but there is a little freeze sensor that changes resistance as the temperature changes. I need to use that to interrupt the compressor relay.
I'm thinking there must be a way to use a simple transistor based circuit so when resistance reaches a threshold, it stops the relay trigger power. Pretty simple but I dont know enough to design something, so looking for some suggestions.
Thank You!
