Query: Fan thermostat

This control is easy to install and adjustable. Alot of cars fry their motors because the owners are not aware of their fans not working. If your fan is not working and it checks out electrically good and it is too hard to diagnose why it isn't working, then install this control and ,or add, a new Hayden fan if the fan is bad. The instructions are easy to follow and you can call Hayden for help if need be.
