What happens if condenser fan goes out?
What happens if condenser fan goes out?
When the condenser overheats, all of the components of the AC system will begin to overheat until they eventually get hot enough to burn and emit an odor. A failed fan will not only fail to produce cold air, but can even result in damage to the AC system due to overheating.
Can a car run without radiator?
It can absolutely be started without a radiator. You will not cause any damage as long as the engine does not overheat. If you don’t run it long enough for the engine to get too hot, it’s not an issue.
How do you know if your condenser fan motor is bad?
5 Signs Your AC Fan Motor Is Bad
- The cooling fans won’t turn on.
- The fan turns on when the AC is running, but the blades rotate slowly.
- You can hear a rattling noise coming from the condenser unit.
- It smells like something’s burning.
- Blown fuse.
When does the condensor fan and radiator fan stop running?
Bingo, after a while BOTH radiator fan and condensor fan stopped running (high speed or low), and then for 30 sec of so, they will try to spin up for a split sec and stopped again and so on… It is at this moment the air becomes warm. This problem is not easily duplicateable.
Why does the radiator fan not run at highway speeds?
At highway speeds, when there’s sufficient airflow over the condenser and radiator, the switch stays open and the fan doesn’t run. When the vehicle slows or stops, the a/c pressure rises and the fan runs, regardless of engine temperature. In this arrangement the diode is not needed.
How are the fans on a radiator powered?
The fans are powered by the battery bus and each fan is individually fused by F2 (main fan) and F4 (subfan)—except for low-speed operation! There are no temperature or pressure switches. ECT and a/c pressure are supplied to the ECU from threewire sensors (not shown in the figure) on the ECU’s 5V reference circuit.
How does the heat go out of the radiator?
Of this waste heat on a liquid-cooled engine, about half goes out through the cooling system via the radiator. The term radiator is a misnomer, as almost all of the heat it transfers to the atmosphere is via forced convection.
