Review on AP 4740 Aprilaire Replacement Humidifier Relay by Gabriel Tomato

My April Aire 700 has been running great for 7 years. That winter, the fan case began to hum heavily. I called April Aire Tech Support and they recommended this part. less than 10 minutes to replace the original, just removed the fairing, 4 screws to loosen the fan mount and then I swapped the wires one by one to make sure they all come back in the same order. Put everything back together and everything is now running smooth and quiet. I always take photos before I take things apart, it's always good to have a photo before I take them apart so I can see how everything is put back together, but it's really easy.
