Common Questions

Is the HK70EZ017 plug compatible with universal control boards?
This plug is specifically keyed for Carrier OEM control boards. While some universal boards may accept the pin layout, we recommend verifying the specific pinout and keying against the HVAC manufacturer specifications to ensure a secure lock.

Does this plug include the wire leads or is it the plastic housing only?
The HK70EZ017 is typically provided as a pre-wired harness assembly to ensure factory-spec crimp tension and path resistance, which is vital for furnace diagnostic sensors.

Why is my furnace generating a communication error even with a new plug?
Always inspect the board-side pins for corrosion or thermal stress. If the circuit board plug is secure, the issue may stem from lead wire continuity or the control board's logic processor.
