OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model CP48P248P206010CP

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier CP48P248P206010CP packaged heating and cooling unit. The DSI control board serves as the central command module for the ignition sequence — managing the spark igniter, gas valve timing, flame verification, inducer motor operation, and safety lockout logic. When this board fails, you'll typically experience symptoms such as a no-heat condition, repeated ignition lockouts, failure to initiate the ignition sequence, or erratic furnace cycling that cannot be resolved by resetting the thermostat. Replacing the board with the correct OEM part restores factory-programmed timing and safety thresholds that aftermarket alternatives often cannot replicate precisely.

Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter, phone or camera to photograph all wiring harness connections prior to removal.
