Do you live above 3000 Feet
The cooling fan comes on when the engine reaches a certain temperature and is controlled by a sensor switch that kicks the fan on when the temperature reaches the preset temp.
Do you mean the switch that automatically kicks down the idle when the engine reaches proper temperature to drive and indicates with the red light going out on the dashboard? It is in the thermostat housing I believe.
Check the circuit breakers for both, doubtful both have simultaneously failed.
Not likely, could be hi temp limit switch or bad air flow.
a temperature sensor that detects when the car reaches a certain temperature before it overheats which kicks on the fan to cool the engine. the fan may not be grounded properly which causes the blowing of fuses to prevent a fire.
If it's a Mechanical thermostat it may be out of calibration or out of level.
Furnaces can get loud if they need service. Over time, they get clogged up and dirty, which is not only inefficient and loud, but can be dangerous too. Have it serviced by a qualified professional.
The reason for this is because the furnace has not warmed up yet. The blower kicks on the same time the burner lights. However the furnace does not go into "high fire" until after a period of about 10 min. After this stage is when you will really begin to feel the warm air.
The fan on mine kicks in at 100C
225 degrees
There probably is no problem. When the a/c first comes on the air in the ductwork is at room temperature, or warmer if the duct runs through an unconditioned space like an attic. Once the coil at the furnace has cooled down, it can begin to cool the air that is supplied into the rooms. Try letting the fan on the furnace run continiously while your in a/c mode. You change it at the thermostat. This will give you a more consistant temperature throughout the house and keep air in the ductwork the same temp as in the rooms.
