Lennox Air conditioner fan not working. Lennox Air conditioning is a large part of modern life and there are many innovative ways to cool homes and offices.
You may have your home or office set up so that the temperature can be easily adjusted with a handheld control but what do you do if this suddenly stops working.
If the temperature controls are not working correctly, there could be an easy fix or they may need expert assistance.
Lennox Air conditioner fan not working
Many people assume that any problems with their air conditioner would require an expensive repair but this isn’t always true since it can be easier than you think to fix them yourself.
Here are some common Maytag oven problems and solutions.
Replace Main Control Board
The main control board provides voltage to all of the air conditioner’s components.
If there is a problem with the control board, it might stop providing power to the fan motor.
Control boards are often misdiagnosed, so be sure to check other components before replacing your main control board.
Make sure that all electrical lines are intact and that there are no loose connections or shorts in any lines leading from the main circuit board.
Faulty Temperature Control Thermostat
A faulty fan motor or capacitor is likely to be the cause of the compressor running but not the fan motor.
If both the fan motor and the compressor won’t run, use a multimeter to check the central air conditioner’s temperature gauge for continuity.
If the temperature gauge does not have continuity, it should be replaced. For more information, see your central air conditioner’s wiring diagram. Some temperature gauges may also control a heater.
Blower Motor issue
The blower motor may be burned out or worn out. First, check the fan blades for excess dirt or grime which can stop them from spinning freely.
If this is the case, you simply need to clean the fan blades with a dry cloth and then try again.
Second, make sure that power is getting to the blower motor.
If a hose connected to your vacuum has become disconnected from the motor itself or vice versa then first check that all electrical connections are secure before replacing any parts as they will not help with these problems.
The thermistor detects the air temperature through a sensor attached to the board. If the thermistor is disconnected, this causes a problem with the fan, as it would remain stopped.
To determine whether or not the thermistor has been dislodged, test it for continuity with a multimeter.
The operation of having continuity enables control over whether or not there is a continuous loop being made when electricity runs through it by allowing electricity to flow from one place to another (this circuit is complete).
A capacitor is burned out
A capacitor is found attached to the compressor by electrical wires. If the capacitor burns out, the fan in the freezer will cease to run.
The first step you should take when determining whether or not your capacitor has burned out is to use a multimeter to test its conductivity. If there is no conductivity present, replace it.
The rotary switch has no continuity
The rotary fan switch turns to activate the fan motor. Over time, electrical contact inside the switch can become pitted, preventing it from conducting electricity.
To determine if the rotary fan switch has continuity, use a multimeter according to your air conditioner’s wiring diagram to test the fan switch.
If there is no continuity in the rotary switch, then it will have to be replaced.
Dual Shaft Fan Motor problem
The dual shaft fan motor may be defective. It has two blades, one on either side. The fan blades have a purpose One draws in outside air over the condensing coil to dissipate heat.
The other draws in outside air over the evaporator coil, which tends to get warmer than the condenser coil.
If you notice that rotation on one side of the motor is significantly slower than on the other side then it is likely that bearings in your fan motor are defective and need replacing.
Fan motor won’t run
Try to spin the blade by hand. If the blade doesn’t move, then that’s a sign of it being well attached.
However, if an object is not properly attached, then you need to face the possibility that the assembly isn’t ideal and might will require replacement.
That said, assess whether or not power is being sent to the motor assembly.
If power is indeed reaching the motor but it simply can’t run at all, that also indicates that it will have to be replaced with a brand new one as opposed to just repairing.
