  • The HN51KB024 contactor is recommended to replace the old outdated Honeywell contactor part numberDP1030A5014. Honeywell quit making the DP1030A5014 contactor. The low voltage wiring is different and in my response email below in the “FYI” section I tell how to make make the wiring changes from the Honeywell DP1030A5014 to the HN51KB024. Also, below we have an email from one of our customers who asked m

FYI: This is a question that has been asked by many of our customers when trying to change from the old Honeywell DP1030A5014 to the new HN51KB024.

Question from one of our customers: Hi, I want to purchase this HN51KB024 contactor, however, my contactor is an older one ( photo attached) and is slightly different. Can you direct me as to how the smaller wires would be connected to the terminals that are on opposite sides on the newer model? Thanks,  Jeff

Answer: I have had this question asked many times. Great question! I have been asked this question so many times that I need to make a post about this question as soon as possible. I had to replace my contactor on my Bryant unit with the HN51KB024 a couple of weeks ago and our unit had the older style Honeywell DP1030A5014 contactor installed in it like the old contactor you want to replace. The high voltage wiring would line up the same, but the low voltage wiring would be a little different. I try to explain in the pictures that I copied below. If you have any other questions please let me know.  I recommend making sure that you are getting a minimum of 24 volts AC to the contactor coil when your thermostat/AC system is calling for cooling.  If you are not getting at least 24 volts to the contactor coil then the contacts will chatter (vibrate) the contacts and burn the contactor up quickly. I hope this helps you out and I hope that you have a great day! Steve
