ICM2807

Carrier HK42FZ017 two-stage HSI

Igniter

120 VAC HSI

Motor

Conventional two-heat-speed blower on HK42FZ017 — not Infinity serial VS

Replace list

  • Carrier HK42FZ017 (ICM — that is the list).

Will not replace

  • HK42FZ004–016/034 single-stage — ICM282B.
  • Infinity / Evolution UI plates.
  • 59TP6 / 926T variable-speed Preferred IFC unless the silk is actually HK42FZ017.

Field notes

  • Low-cost two-stage Carrier replacement. Continuous-blower speed jumper on the ICM sheet.
  • Read the silk. A 926T VS board is usually not this part.

Plates that name this carton

  • No universal

    Preferred VS two-stage. Not a 50A55. ICM2807 is HK42FZ017 only — this VS plate is usually not that silk.
