broken vaginalsitila Usually a stuck switch in the motor itself. I would take the motor out (usually really easy job- Make sure that power to motor is off!!) Take it to your local motor shop and usually it will cost anywhere from 25 to 75 bucks to repair, as opposed to the 150 to 300 bucks for a repairman to do it. I used to own a laundromat and did this on a weekly basis. If the weather is to cold to have it out of service for long ask the motor shop if they could possibly fix it at once. For a few bucks more they'll probably do it.
To adjust the blower speed on your furnace, locate the blower motor and find the speed control switch or dial. Turn the switch or dial to the desired speed setting, typically indicated by numbers or labels such as "low," "medium," or "high." Make sure to consult your furnace's manual for specific instructions on adjusting the blower speed.
It should not run continuously. Typically, the fan (sometimes called a blower) will continue to run for a minute or so after the flame is out. This does not consume much energy; it does flush the residual heated air from the ducts. Make sure the fan is set to "AUTO" on the thermostat, to ensure proper cycling.
A blast furnace runs continuously, and input materials are continually dumped in at the top to make their way down through the furnace. Shutting down a blast furnace for relining or other work is a major event in its life.
If the blower is not working on your furnace, you should first check the power supply to the furnace and make sure it is turned on. If the power is on and the blower still isn't working, you may need to check the thermostat settings, the air filter, and the circuit breaker. If these steps don't solve the issue, it's best to contact a professional HVAC technician for further assistance.
Your furnace may make a loud noise when it turns on due to issues such as a malfunctioning blower motor, loose components, or a clogged air filter. It is important to have a professional inspect and repair the furnace to prevent further damage.

A rattling noise from your furnace could be caused by loose components, a malfunctioning blower motor, or a problem with the heat exchanger. It is important to have a professional HVAC technician inspect and repair the issue to prevent further damage.
There could be any number of reasons for this. Perhaps, depending on your make and model of furnace/and stat, perhaps the "fan" terminal is energized to circulate the air. That is a simple programming issue. Another would be a short between (normally) the red and green low voltage wires (where red=24v and green is "Fan" (G) terminal at the furnace. Another would perhaps be a problem with the circuit board at the furnace. If you have an older furnace, where there is (normally a honeywell "silver/galvanized enclosure box mounted normally above the gas valve and attached to the furnace) where there is an insertion type combination fan limit switch (you should be able to remove the honeywel coer using just your fingers and find a wheel/dial underneath), this part could be "going out" and would require replacement. If the fan comes on after about 5 minutes after shutting down after a call for heat, perhaps not all of the heat was removed from the furnace and warms up the comb. fan/limit switch again which in turn cycles the blower motor. This too would be a sensitive comb. fan/limit switch and requires replacement. If you have a circuit board, I would try removing all of the 24 volt wires from the (r,g,y,w,c) terminals, just to eliminate any possibility of the stat, or stat wire to be the problem. make sure to put the blower door back in place to ensure the "blower door safety" switch is "closed".
A common problem is this situation is the thermostat itself, though it also depends on the make and model. A proper 'diagnosis' would be found by a professional, especially if it's been awhile since the unit has been serviced.
To properly wire the furnace blower motor for safe and efficient operation, follow these steps: Turn off the power to the furnace before starting any work. Identify the wires for the motor, typically labeled as high speed, medium speed, and low speed. Connect the corresponding wires from the motor to the appropriate terminals on the furnace control board. Make sure all connections are secure and properly insulated to prevent any electrical hazards. Test the motor to ensure it is running smoothly and efficiently before closing up the furnace. If you are unsure about the wiring process, it is recommended to consult a professional HVAC technician for assistance.
Check breakers first. Then check to see if there is a disconnect switch on furnace (usually a 2" x 4" silver box attached to furnace) and see if fuse is blown or switch is off. Also if you have had your blower door off there is a safety switch for door. Make sure door is secure. There are multiple reasons that it might not come on but this can narrow it down a bit
