People also ask, where is the blower motor reset button?

Examine the exposed components in the furnace cabinet to locate the blower motor; look for a small silver box positioned toward the top of the cabinet. Mounted just above this box you should see a small round component with a raised red or white button at the center; this is the blower reset switch.

Subsequently, question is, how do I know if my blower motor is bad? Symptoms of a Bad or Failing Heater Blower Motor

  1. Weak airflow from the vents. One of the first symptoms of a potential problem with the vehicle's heater blower motor is low airflow from the vents.
  2. Fan only blows at certain speeds. Another symptom of a bad or failing heater blower motor is a motor that only functions at certain speeds.
  3. No air from the vents.

Similarly one may ask, what can cause a blower motor to stop working?

In a situation where the motor doesn't work on any speed, the most likely causes are: a blown power supply fuse, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely. Start by checking the blower fuse and HVAC controller fuse.

How does a reset button work?

Hardware reset buttons on PCs work by causing a momentary power interruption to the CPU, which resets it and causes the computer to reboot. Unlike Ctrl+Alt+Del, pressing the reset button causes the BIOS to perform the POST check.

There are several different reasons why the flame might go out. They are usually related to an interruption in the fuel supply.

How do I reset my thermostat?

Here are the steps you need to take to reset your AC thermostat.
  1. Shut Down Your AC at the Thermostat. The first step in resetting your AC thermostat is to turn it off at the AC unit.
  2. Find Your Circuit Breaker Box.
  3. Reset the Circuit Breaker for Your AC Unit.
  4. Wait 30 Seconds.
  5. Turn the AC Thermostat Back On.

Why is my furnace not blowing hot air?

Furnace overheating can be the cause of your cold air dilemma. Changing the dirty air filter can solve this problem. The dirty air filter blocks the airflow, causing the furnace to run longer to heat your home until it overheats. It is important to note that constant overheating can damage your heat exchanger.

Why is my heat not coming on?


If your furnace does not heat at all. Thermostat malfunctions cause most heating system failures. Other causes include a tripped circuit breaker or blown fuse, or—in the case of combustion furnaces—a pilot light that has gone out. 2 Be sure the furnace's circuit breaker is on or that its fuse has not blown.

How do you reset a overload switch?

Resetting a Breaker After An Overload
  1. Identify your tripped breaker. Open your breaker box door and look for the breaker in the off position. Most breakers come with an orange or red marker indicating an overload.
  2. Flip the switch. Push the switch into the on position to reconnect your circuit and restore power.

What fuse is for the blower motor?

The blower motor pushes the warm or cold air through your vehicle's ventilation system. The blower motor is powered by a fuse-like device called a relay. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown.

What are the signs of a bad blower motor relay?

Symptoms of a Bad or Failing Heater Blower Motor Resistor. Common signs include the car's heater not working or getting stuck on a certain speed, or something getting jammed in the blower motor.

How much is a blower motor relay?

The average cost for a blower motor relay replacement is between $74 and $85. Labor costs are estimated between $38 and $49 while parts are priced at $36.

What does a bad blower motor sound like?


You might hear this as a noise coming from directly behind the vent, perhaps a light slapping, or a sudden pop before you notice a problem with airflow. Whirring noises might also result from a bad bearing in the motor.

Why is there no air coming out of my car vents?

Common reasons for this to happen: Blown fuse: Like many electrical units in your car, the ventilation system relies on a fuse for overcurrent protection. If the ventilation system's fuse blows, then the circuit will stop working, and there will be no power for the vents. Bad relay: A bad relay can also be responsible.

Why does my blower motor work sometimes?

If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn't working. Blower resistors are small parts that can become corroded or just burn out, and a new one often costs less than $50.

How much does it cost to fix a blower motor in a car?

Know what price you should pay to get your vehicle fixed.

How do I test a blower motor resistor?

Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.

Can a blower motor get weak?


Weak Airflow from the Vents
This is usually the first indication that you may have a faulty blower motor. If the airflow coming out of the vents is weak, it can mean that your blower motor is having a hard time pushing enough air through the ducts to achieve your desired temperature.

Is it the blower motor or resistor?

The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. It is responsible for controlling the blower motor's fan speed. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system.

Where is the AC blower motor?

The blower fan is located inside a horizontal air conditioning unit in many home air conditioning systems, especially when the air handler is located in an attic or crawl area.
