What are the relays on a John Deere blower motor?
You should have three fuses and one relay controlling the fans. Fuses F05/1, F05/13, and F05/14 all provide power to the blower motor circuit. The K10/1 relay is the primary relay.
Why does my blower not work at high speeds?
Blower works on slow speeds, but not on high speed. Check for bad fuse or bad high speed relay. Swap the high speed relay with another relay with the same part number. Also, check the fuse for the control side of the high speed relay. Make sure the ground side of the high speed relay is working. Blower works on some speeds but not others
How can I tell if my blower motor is failing?
On all systems, a failed blower motor is least likely. Blower motors generally don’t fail out of the clear blue. In most cases, they start to fail by making a high pitched squeal or screeching noise that indicates the bearing is failing.
How to test the blower motor on a John Deere?
You will see both blower motors and the fan speed resistor once you have the cover off. Turn the key to run and the blowers on low and give each blower a spin to see if it reacts. You can test for power input and output at the blower motor resistor. Please let me know if I can be of any further assistance. Thanks, Kevin
Why is my blower motor relay blowing fuses?
Thus, blown fuses could be a sign of relay issues. Blower motor relays handle a large amount of current. Malfunctioning relays aren’t able to distribute their load properly.
What should I do if my blower motor is not working?
The blower motor is crucial to the proper functioning of your HVAC system. This video will show you how to properly diagnose your blower by using the multimeter to perform an AMP draw as well as replacing the blower motor relay. Loading…
What to do if your AC or heater is not blowing?
If your Blower Motor for the AC or Heater suddenly stopped blowing, look here first, it might save you several dollars. Situation, we have a friend that owns a 2017 Chevy Trax LT, she is a nurse who works with my wife, single mom and on a single mom budget.
Can a TDR be used on a blower motor?
A normally closed delay-on-break TDR can be used to hold the blower motor in operation for a specified time after the cooling compressor has been turned off by the thermostat. This allows the residual cooling effect in the evaporator coil to be used to provide additional BTU’s of cooling after the compressor has stopped.
