The fan continues to run after the compressor shuts off to help dissipate heat from the system and maintain efficient cooling. This process, known as "post-cycling," allows the remaining heat in the condenser coils to be expelled, preventing overheating and improving overall system efficiency. It also helps to ensure that the indoor air remains evenly cooled, enhancing comfort in the space. Additionally, some systems are designed this way to prolong the lifespan of the components by preventing thermal stress.
The compressor continues to run after the condenser fan shuts off because it needs to maintain the pressure and temperature of the refrigerant in the system. If the compressor stops running, it can lead to an increase in pressure that could potentially damage the system.
The AC fan keeps running after the compressor shuts off to help distribute the remaining cool air throughout the room and prevent the system from overheating.
When alot of engine power is needed, the A/C compressor will be shut off to reduce engine load.
The fan motor may continue to run after the compressor shuts off to ensure that any residual heat is dissipated from the condenser coils, enhancing overall system efficiency and preventing overheating. This is a normal operation in many HVAC systems designed to optimize performance and maintain comfortable indoor temperatures. Additionally, the fan helps circulate air throughout the space, promoting even cooling. If the fan runs for an extended period, it may indicate a potential issue with the thermostat or control system.
The engine cooling fan will continue to run because the engine is hot. Once the engine has cooled down the fan will shut off. If it never shuts off you may have a bad temp switch or relay.
If you have the selector knob on defrost it will also run the air conditioner compressor.
Main components of AC are compressor & fan motor. The louvers are operated by fan motor which is powered separately. When the louver is off, it doesn't affect compressor work. - Be-Cool Expert <><><> possibly a stuck contacter in the outdoor unit. or your indoor fan is overheating and shutting off <><><> could be many different things. Depends on what system you have. Some of the newer machines are controlled by integrated circuit boards. Its a possibility that your indoor blower could be tripped off on thermal overload but honestly I doubt it. Possible contact could be stuck on compressor. T stat could have a problem but would need to know if the compressor ever turns off after the "fan inside the house clicks off"
runs for 4 min or whatever the limit switch is set at
Only if you shut it off. :)
It comes on long enough for the shocks to fill up and then shuts off. Is your car raised when it shuts off? If the shocks are in good shape without leaks, that's usually the time the compressor takes to pump up the shocks.
Your fan relay is stuck or you have a bad tstat. Check your auto fan (summer fan switch ) on your furnace if equipped. Mostly older oil furnaces.
The fan should run for about 3-5 minutes after the furnace shuts off to help distribute the remaining heat throughout the house.
