Question about Ruud Central System Air Conditioner
When thermostat is shut off, squirrell cage fan keeps running. faulty thermostat or motor? thank you. RT
Ensure you don't have a short in your therm wires. Disconnect them, if the furnace continues to run, you have a lockout problem at your furnace. When the motor on the fan fails, it wont run. Check for led codes on the control board. If you don't have led codes, turn off the power to the furnace at the breaker, and watch the unit. If nothing happens, connect the thermostat. If nothing happens still call for heat. Let the therm run through it's cycle, and if the bower runs continuous again, let me know we can walk through that situation.

Probably the fan switch stuck on the fan combination control or improperly adjusted. Turn power off, remove red wire on the relay from the fan motor. Isolate so no short will happen and turn power on.The motor should not run. The fan relay could stick also. You will have to use a volt meter and see if there is voltage on the coil terminals on the fan relay. Put 1 lead to ground and touch only the terminal for the coil on the relay with the other meter lead.It should not have 120volts. If it does it is not the fan relay but possibly a limit sending power to the relay. Try that first thank you J
