Check the blower motor capicator. It should be mounted close to the motor with 2 wires to it (brown,brown/white). Turn the blower on the thermostat and spin the squirrel cage by hand and see if it runs after by itself. If it does then definitely the capicator is bad .If it still doesn't run then check to see if there is voltage going to motor. If thermostat is calling for fan and there is voltage present at the motor terminal then the motor is bad
Hello, air conditioners will freeze either due to low airflow.....such as dirty filter, dirty evaporator coil, weak or not running blower motor. Also, a low refrigerant charge can cause the unit to freeze up.
The best way to really clean the squirrel cage is to remove the entire indoor blower motor housing assembly out of the furnace then remove the squirrel cage from the motor shaft and pressure wash the squirrel cage. Make sure you don't use to much water pressure as you might knock off any balancing weights that may be attached to the one or more of the vanes. Make sure the cage is completely dry before you re-install it back on the motor shaft.
outdoor fan if it hit your condenser coil your toast, if its indoor blower (squirrel cage) lets say about $500- $700 if you have pro do your work. have a pro do it NATE certified
If the blower is made of plastic it does not have a set screw. You most likely need a new squirrel cage. They are formed to the shaft and have a compression ring that holds them in place.
