A dedicated printed circuit board assembly used in the Cleanstar B‑18 series dryer—likely an earlier revision of the main power board (EC‑1801E).

Functions as the primary electronic control module, governing inputs such as airflow speed and heater activation through integrated switching components.

Likely orchestrates power distribution, safety protections, and interlock logic between the variable speed control and the heating element, similar to other EC‑series boards (like EC‑1802E).

Designed as an OEM replacement, matching original Cleanstar’s connector layout, mounting configuration, and signal wiring for seamless installation.

Contains components such as relays or triacs, thermal protection cutoff, and possibly status LEDs or diagnostic traces.
