Lockout

Blower HP / shared-data mismatch

Connected motor horsepower does not match the shared data set.

Walk b2 in Diagnose

4 plates — walk the one on the cabinet

First check

1 Read the plug / card on THIS cabinet

On Daikin DM80VC the model plug or shared-data card must match this cabinet size. A 100 kBtu plug in an 80 cabinet overfires and limits. A leftover memory card after a control swap throws d0/d4-class codes. Wrong replacement motor.

Expect: Plug / card part matches the rating plate and the replacement control bulletin.

The rest of the walkthrough is Diagnose.

On the plates

  • Wrong replacement motor.
  • Memory card / shared data for THIS DM96VC cabinet — a card from a different input or an AMVM97 will b2.
  • Do not load a DM96VC or AMVC96 card into this cabinet.
  • Correct memory card / learn for DM97MC0603BN-class SKU.

Plates that use b2

Same number, other makers
