Fan Only Comes On When Ac Is On

Look for where a sensor or a switch is located on the high pressure line rises over an operative threshold.

Black ceiling fan with glass light. Also the fan may be on continuously when the ac is operating. Test to make sure you are getting 24 to 28 volts ac between the g green and c com terminals on you fan center or control board. As for the engine coolant temp sensor if the coolant is not hot enough to make the fan come on then there is no need for the fan yet and there is no problem.

Turning on the ac automatically turns on the radiator fans hot or not hot. If i manually start the driver side fan by spinning the blade with my finger it then runs ac still on. In order for the ac condensor to do its job it must stay as cool as it can.

The fan mode and switches are one such example. A qualified technician such as one from yourmechanic will be able to diagnose your overheating problem and perform any repairs required. It may seem logical to think that a fan for an air conditioner is the same as a fan that you use in a room thought this is not the case.

Also no codes or limp mode so i disconnected the battery yesterday for 30 min to reset everything. Anyway when i turn on the ac only the one on the passenger side starts. I noticed my cooling fan stopped working and would only come on when i had the ac on.

The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units. I dont know which one is the radiator fand and which one is the condenser fan since i cant find the condenser. The condenser fan if it has a dedicated fan or the radiator fan most always comes in with ac on when the compressor discharge pressure or alternatively the liquid line one.

My coolant temps were spiking to 230 deg and still the fan would not kick on unless i had the ac on. Fan will not come on in the on position or your fan will not come on when you turn the thermostat down in the air conditioning mode. One note on the fans.
