Review on 🔴 Efficient Cooling Solution: Derale 16795 PWM Fan Controller in Vibrant Red by Chad Delgado

I installed this product using the supplied wiring diagram in combination with a powerful 2 stage Derale fan. In the original configuration, the fan turned on immediately after starting the car, and not at operating temperature as expected. Initially, the air conditioning lock worked as intended. Then one day, for no known reason, the fan stopped working. I was lucky enough to get a replacement from Revain as the 30 day refund period had expired but it was still under the manufacturer's warranty. The rewiring and installation was identical to my original wiring. However, this time the fan turned on at high speed immediately after connecting the negative cable of the fan controller to the negative terminal of the battery and kept the fan running continuously even when the car was not driving. After troubleshooting the sensor and wiring with tech support, I was told that the replacement unit was probably defective. I finally gave up after receiving two defective parts, returning both original and replacement parts and switching to another brand. Derale's technical staff was difficult to reach on the phone and responses to emails were slow or non-existent. I would think twice before spending money on this part.
