Product ReviewsHayden 3653 Electric Fan Controller

Works great

I used this to bypass the computer that controls the AC in my car. My AC stopped working and after trying all the easy fixes I found a video on youtube by scotty kilmer where he uses an adjustable thermostat to get the AC compressor to come on. Low and behold it worked!Read full review...

Re-purposing ...

I have been searching for just the right adjustable thermostat for quite a while to use with my home hot water boiler heating system. Radiators in each room and I wanted to control a small fan to help circulate air through the radiators. These fan controls are working great!Read full review...

Don't bother with the cheapo copy

This is the one you want; it's adjustable from ambient temp and up. The cheap copy only comes on once the motor is already too hot. I've installed these on 4 of my vehicles and they are the best for reliability and adjustability.Read full review...

Good Quality For Price

Installed easily and looks quality. Ease of installation. Seems the thermo switch is strong enough to operate my fans without a relay. Time will tell!

Simply Works

I've used these before and they work well, last forever and have a wide range of temperature settings.
I use these to trigger a heavy duty 30 amp relay to run power to radiator fan.

Good unit for the price

Instructions were a little vague. It functions. Was easy to adjust. Jury is still out on long term dependability.
