Why the Cooling Fan Relay Might Fail to Work?

It has been observed that cooling fans do not work as expected when the fan relay is bypassed. The relay is responsible for switching on the fan if the temperature reaches a particular level, and if this is bypassed, then the fan will not turn on even if the temperature reaches that point.

The problem with this is that the temperature rises to a high level. In some cases, the temperature might rise to a point where the machine overheats and stops functioning.

There are a number of reasons why the cooling fan relay might fail to work as expected.

1. Low power

This is one of the most common problems. As the temperature is raised, the fan relay tries to switch on the fan, but it does not get enough power to start working.

2. Circuit board failure

The fan relay is made up of a circuit board, and if this circuit board fails to work as expected, then it might stop switching the fan on.

3. Fan failure

If the fan itself fails, then the fan relay will not be able to detect that the fan is not turning on.

4. Fan overload

The fan relay might start to switch on the fan, but once the speed reaches a certain point, the fan will stop working.

5. Excessive load

If the fan is running too hard, then it will burn out.

6. Excessive heat

If the machine is working hard for a long period of time, then it will overheat and it will stop working.

7. Improper installation

The fan relay is usually connected to the motherboard, and if the installation is not done properly, then the relay might not work as expected.

8. Electrical interference

The fan relay is connected to the motherboard via a wire, and if there is any electrical interference, then it will stop working.

9. Faulty wiring

The fan relay is usually connected to the motherboard and if the wiring is faulty, then it will not work as expected.

10. Electrical shock

The fan relay is connected to the motherboard and if there is any electrical shock, then it will not work.

To bypass this problem, you need to disconnect the power supply and then turn on the fan. If you see that the temperature has started to rise, then you can turn the fan back on, and then reconnect the power supply.
