How the cooling fan relay works in low speed and high speed?
During low speed operation, the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.
Do both cooling fans run at the same time?
The answer to your question is yes both fans will run when your at 230 degrees, if you have the parking lights on and your at 212 degrees one fan will come on, and when you have the air conditioning on you have one fan on as well.
Does radiator fan affect AC?
Likewise, does radiator fan affect AC? Yes, a broken radiator fan can cause the air conditiong to stop working. The AC system depends upon being able to dissipate heat into the engine coolant. You really need to have the fan replaced, or at least, have a diagnostic check to see what is causing the fan to stop working.
Will AC work without cooling fan?
In conclusion, you can run the indoor fan without running the “Outdoor Unit” (Outside fan unit), with the understanding that the Air Conditioning will not function until the thermostat calls for cooling. Of course, the same is true for the heating cycle.
Does running the AC fan use a lot of electricity?
Most fans are quite energy efficient, especially in newer systems. The fan itself runs about as much energy as a refrigerator would. This can still add up to $50 a month, or $600 a year. This cost can be even higher if you consider the AC unit working harder to counteract the effects the fan may have.
Should I leave my fan on auto or on?
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
How much does it cost to run a fan 24 hours?
A contemporary DC fan typically costs less than a penny per hour to run at its highest speed. Leaving such a fan on high speed 24 hours a day for a month costs about five dollars.
